How Short Walks After Eating Help Regulate Blood Sugar Levels

Posted on October 7, 2026 by Patrick Hercules

Blood sugar, or blood glucose, is the main sugar found in the blood. It is our body’s primary source of energy and comes from the food we eat. When your blood glucose goes up, it signals your pancreas to release insulin. However, when things aren’t functioning properly, you can develop high blood sugar, which means there is too much sugar in your bloodstream. You may have high blood sugar due to:

Your body isn’t using insulin correctly
Your pancreas doesn’t make enough insulin

Elevated blood sugar levels can cause blood vessel damage, which can lead to serious complications, such as:

Heart attack
Stroke
Diabetes-related retinopathy, which can cause blindness
Diabetes-related nephropathy, which can lead to kidney failure
Nerve damage

Our blood sugar naturally rises when we eat and is highest about 30 to 90 minutes after eating. However, frequent or especially high spikes in blood sugar levels can increase the risk of or worsen diabetes.

Fortunately, there are several ways to lower blood sugar levels into a healthy range, such as eating healthy, getting regular exercise, and managing stress. Another way to manage blood sugar levels is to take a short walk after eating.

Research shows that a short walk after a meal can:

Prevent your blood sugar from spiking as high as it would if you ate and remained seated
Keep your insulin levels stable

Walking for ten minutes, or as little as two to five minutes, can lower your blood sugar.

When walking after a meal, it is important to stay safe. Some safety tips to keep in mind when walking include:

Go slow and gradually increase your physical activity
Avoid environmental triggers, such as high heat and humidity, environmental allergens, cold air, and safety hazards
Fall prevention for those who are 65 years of age and older

Wellness Wednesday Tip: Healthy Eating

Posted on August 12, 2026 by Patrick Hercules

Eating healthy can be difficult, especially when you don’t have the time, and there is the convenience of fast-food restaurants and processed foods.

Most people in the United States need to eat more nutrient-dense foods and limit highly processed foods, added sugars, added sodium, and refined carbohydrates.

Healthy eating emphasizes protein, dairy, vegetables, fruits, healthy fats, whole grains, and limiting added sugars.

The best way to practice healthy eating is to aim for having a variety of colors on your plate. Fruits and vegetables such as oranges, tomatoes, dark leafy greens, and fresh herbs are full of vitamins, fiber, and minerals.

Too much added sugars in your diet, such as cane sugar, corn syrup, dextrose, fructose, maple syrup, and honey, can contribute to weight gain, obesity, type 2 diabetes, and heart disease. Sugary beverages are common sources of added sugar.

To limit added sugars, you can:

Drink water with berries or slices of lemon, lime, or cucumber instead

Read nutrition labels and choose foods with no or lower amounts of added sugars

Limit sugary snacks and snack on fruit or vegetable slices instead

Add fruit to your whole grain cereal or yogurt for sweetness

Avoid adding flavored syrups to your coffee

Eating too much sodium can raise your risk of high blood pressure, heart attack, and stroke. More than 70% of the sodium Americans consume comes from packaged or prepared foods. While sodium has several forms, 90% of the sodium we consume is from salt.

To cut back on sodium, you can:

Read the nutrition facts label to find foods that are low in sodium or lower-sodium options

Buy unprocessed foods, such as fresh or frozen vegetables, to prepare at home

Avoid highly processed foods, such as breads, pizza, and deli meats that are high in sodium

Fiber helps maintain our digestive health and helps us feel fuller longer. Fiber also helps control our blood sugar and lowers our cholesterol levels. Fruits and vegetables, whole grains, legumes, nuts, and seeds are good sources of fiber.

To increase your fiber intake, you can:

Start your day with a whole-grain cereal, such as oatmeal

Add fresh fruit with a meal or as a dessert

Slice raw vegetables for quick snacks

Top your whole-grain cereal with berries, pumpkin seeds, or almonds

Add a half-cup of beans or lentils to a salad to add texture and flavor

Protein is also an important part of healthy eating. Including protein-rich foods in your diet is essential for maintaining overall health and well-being.

Protein options include:

Eggs

Poultry

Seafood

Red meat

Beans

Peas

Lentils

Legumes

Nuts

Seeds

Soy products such as tofu

Good nutrition is about choosing healthy foods and beverages on a consistent basis. Eating healthy, whole, nutrient-dense foods can support longevity and vitality, and lower your risk of heart disease, certain cancers, and chronic illnesses, such as diabetes and obesity.

Legionnaires’ Disease

Posted on July 18, 2026 by Patrick Hercules

Legionnaires’ disease is a serious, life-threatening type of pneumonia caused by breathing in mist or getting water that has been contaminated with Legionella bacteria in the lungs.

You can also get Legionnaires’ disease from:

Hot tubs

Shower heads

Faucets

Humidifiers

Decorative water features

Heating and cooling systems, usually only in large buildings

Intubation during surgery

Dirt

Legionnaires’ disease is not contagious. Most people don’t get Legionnaires’ disease, even if they have been around Legionella bacteria. But some people are more likely to get sick with Legionella infection than others. You can have an increased risk of getting Legionnaires’ disease if you:

Are older than 50 years old

Smoke or used to smoke cigarettes

Have a weakened immune system caused by certain medical conditions, such as HIV, diabetes, cancer, and kidney or liver disease, and medications that can compromise your immune system

Have a long-term respiratory illness, such as chronic obstructive pulmonary disease (COPD) or emphysema

Live in a long-term care facility

Have stayed in a hospital recently

Have had surgery requiring anesthesia recently

Have received an organ transplant recently

Legionnaires’ disease causes pneumonia-like symptoms that start two to 14 days after exposure to Legionella. It can also cause neurological and gastrointestinal symptoms.

Symptoms of Legionnaires’ disease include:

Fever (often over 104⁰F/40⁰C)

A dry cough

Shortness of breath

Diarrhea

Muscle aches

Headache

Nausea

Confusion

Coughing up blood

Abdominal pain

The most common way to diagnose Legionnaires’ disease is with urine and sputum tests. A healthcare provider may use imaging tests, such as an X-ray or CT scan, to get pictures of the inside of your chest. They will also take a physical exam and ask you about your health and travel history.

Other tests used to diagnose Legionnaires’ disease can include:

Blood tests

Bronchoscopy

Thoracentesis

The treatment for Legionnaires’ disease is antibiotics, either intravenously or in pill form. If you are having trouble breathing, a healthcare provider may give you treatments to help you get enough oxygen. You will probably have to stay in the hospital while you are being treated.

You can reduce your risk at home by making sure shower heads, faucets, hot tubs, and humidifiers are properly cleaned.

If you are experiencing any symptoms of Legionnaires’ disease, you can schedule an appointment with a doctor at Jamaica Hospital Medical Center’s Ambulatory Care Center. Please call (718) 206-7001.

Common Vaccines That Can Prevent Chronic Diseases or Some Cancers

Posted on July 16, 2026 by Patrick Hercules

Vaccines don’t just protect you from specific infectious diseases or help reduce the severity of symptoms if you get sick. They also play a significant role in preventing you from developing common chronic diseases, including certain cancers.

What’s more, there is an increasing amount of research that has shown that vaccines can reduce the risk of developing dementia and heart conditions.

Here are some common vaccines that can prevent chronic diseases and some cancers:

HPV Vaccine

Human papillomavirus (HPV) is a common infection spread by skin-to-skin contact, often through sex, and is responsible for most cervical cancers. It can also cause a large number of lower genital cancers and certain head and neck cancers.

Studies have shown that rates of HPV infection, early signs of precancer, and cervical cancer have fallen since the HPV vaccine was introduced. A 2024 study of an estimated 3.5 million participants found fewer cases of HPV-related cancers in people who were vaccinated. Another study found that cervical cancer deaths among women younger than 25 years old dropped more than 60 percent in recent years, with researchers suggesting that the significant decline was most likely the result of vaccinations.

The HPV vaccine should be administered to all young people between the ages of nine and 26. It can be given to people up to the age of 45; however, the vaccine is less effective the older you are. Two doses of the vaccine are recommended for most people younger than 15 years old, and three shots for people between 15 and 26 years old and those who are immunocompromised.

Shingles Vaccine

Shingles is caused by the same virus that causes chicken pox. Unfortunately, the virus doesn’t leave your body after you have recovered from chicken pox and stays dormant in your nervous system, and for some people, it can reactivate and cause a painful rash. In the U.S., an estimated one million people get shingles each year, and for certain people, it can sometimes also cause lifelong chronic pain conditions or other serious complications, such as vision loss.

According to the Centers for Disease Control and Prevention (CDC), the shingles vaccine is 97 percent effective in preventing shingles in adults between 50 and 69 years old.

Additionally, many large-scale studies have reported a connection between the shingles vaccine and reduced risk of dementia. There is also research that suggests the vaccine could reduce the risk of cardiovascular events such as stroke, heart failure, and coronary artery disease. The CDC recommends two doses of a shingles vaccine for adults 50 and older, or people 19 years or older with weakened immune symptoms. The chicken pox vaccine for children can help prevent shingles when they’re older.

Hepatitis B Vaccine

The hepatitis B virus is a leading risk factor for liver disease and cancer later in life. It can be contracted through sexual contact, needles, and childbirth, and can be passed from person to person through blood, semen, or other bodily fluids.

Acute hepatitis B can be a short-term illness that happens within the first six months of exposure to the virus. It can cause people to have no symptoms or only mild sickness. However, the illness, which is a liver infection that can become a lifelong chronic condition if left untreated, could lead to cirrhosis and liver cancer. It is recommended that all infants receive the vaccine at birth, with the series of shots to be completed in the first 15 months of their life.

Flu, Coronavirus, and RSV Vaccine

Vaccines that help prevent infections from respiratory viruses are important because they protect us against serious disease, as well as flare-ups or worsening of existing chronic health conditions.

A study done in 2020 found higher rates of severe flu infections among adults with certain chronic medical conditions, such as diabetes, kidney disease, congestive heart failure, coronary artery disease, chronic obstructive pulmonary disease (COPD), and asthma. Additionally, a study of 46 million adults observed that the incidence of heart attacks and strokes decreased after people received coronavirus vaccinations.

The CDC recommends that everyone six months and older should get an annual flu shot.

It is also important for those who have chronic conditions to get the coronavirus and RSV vaccines.

RSV can be devastating for children and elderly people. Getting the RSV vaccine is recommended for babies, pregnant women to protect their babies, adults ages 50 to 74 with chronic health conditions, and all adults 75 and older.

Bacterial Vaccines

Bacterial infections such as meningitis and pneumonia can also lead to chronic disabilities or even death.

The longer a person has a meningitis infection, the greater the risk of the infection causing serious complications such as hearing loss, vision troubles, memory issues, learning disabilities, brain damage, seizures, and kidney failure.

Pneumonia can have long-term effects, such as depression, heart disease, and blood vessel diseases that worsen. According to the National Heart, Lung, and Blood Institute, pneumonia could cause kidney, liver, and heart damage due to the organs not getting enough oxygen to function properly, or because of the immune system responding negatively to the infection.

Both bacterial meningitis and pneumonia can lead to sepsis. If treated early, a person suffering from sepsis can recover completely; however, others might experience long-term effects, including insomnia, nightmares or hallucinations, panic attacks, joint and muscle pain, decreased cognitive function, and organ failure.

The CDC recommends all preteens and teens, as well as children and adults who are at an increased risk, receive the meningococcal vaccine, as it protects against the disease that causes meningitis. Children five years and younger and adults 50 or older should receive the pneumococcal vaccine, which helps prevent pneumonia and other infections, including meningitis and sepsis.

It is important to remember that getting vaccinated is the best way to protect against worsening or serious symptoms of illness and developing chronic diseases and cancers.

Managing Diabetes In The Summer Heat

Posted on July 14, 2026 by Xavia Malcolm

How Does Hot Weather Affect Diabetes?

Extreme summer weather can negatively affect our health. The combination of high temperatures and humidity can be dangerous, especially for those living with diabetes.

People with diabetes are at a higher risk of developing heat-related illnesses than others. They are more vulnerable because high temperatures can change how the body uses insulin. High temperatures can cause blood vessels to dilate, accelerating insulin absorption and therefore leading to a drop in blood glucose.

Furthermore, high heat can lead to dehydration. The Centers for Disease Control and Prevention (CDC) reports that people with diabetes get dehydrated more quickly than those who do not have the condition. This risk is driven by the following factors:

Having high blood sugar levels leads to frequent urination, causing dehydration
Diabetes can affect the body’s cooling system (Diabetes may damage the nerves that control sweat glands and blood vessels, making it harder for the body to regulate temperature, increasing the likelihood of overheating and dehydration)
Many people with diabetes also take medications such as diuretics for high blood pressure; these medications increase fluid loss and the risk of dehydration.

Lastly, extreme heat can also damage diabetic medications, such as insulin, as well as medical devices, including insulin pumps and blood sugar monitors.

Safety tips for managing diabetes in the heat

Following these precautions can help protect your health this summer, so you can enjoy the weather:

Stay hydrated- drink plenty of water (even if you don’t feel thirsty) and avoid or limit sugary drinks, alcohol, and caffeinated beverages
Keep medications, supplies, and devices out of the heat and store them in a cool place
Check your blood glucose levels regularly
Avoid outdoor activities during peak heat hours
Dress for the weather by wearing clothing that keeps you cool
Wear sunscreen

Most importantly, pay attention to the signs of heat-related illnesses and diabetic complications. Look for symptoms such as hot, dry skin with no sweating, rapid breathing, dizziness, nausea, extreme thirst, blurred vision, and headaches. If you notice any of these symptoms, take appropriate action, and when in doubt, seek immediate medical attention.

How to Improve Your Gut Health and Balance Your Gut Microbiome

Posted on June 19, 2026 by Patrick Hercules

There are trillions of beneficial bacteria living in your gut, or gut microbiome, that are essential to your health and well-being. The gut microbiome plays an important role in strengthening your immune system and regulating daily bodily functions, including hunger signals and mood fluctuations.

The gut contains 95 percent of the feel-good hormone, serotonin, which means what you eat can impact your ability to respond to stress, reduce anxiety, and help the body fight off germs, viruses, and bacteria that could make you sick.

When you have an unhealthy gut, it can cause several diseases and conditions, including:

Inflammatory bowel disease

Obesity

Small intestinal bacterial overgrowth

Insulin resistance and other endocrine disorders

Mental health conditions and neurological disorders

Asthma

Various cancers

There can be several signs of an unhealthy and imbalanced gut, including:

Intolerance to certain foods

A frequent upset stomach

Intense cravings

Skin irritations

Autoimmune disorders

Intense cravings

Migraines and frequent headaches

Difficulty sleeping or excessive fatigue

Irritability or other mood changes

Changes in bathroom habits

The most direct and effective way to improve your gut health is through your diet by getting enough dietary fiber. Dietary fiber is the key nutrient for maintaining the diversity of gut microbiota. Having low gut microbiota diversity is associated with many chronic inflammatory diseases, such as:

Obesity

Diabetes

Irritable bowel disease (IBD)

Several foods are high in fiber, including:

Fruits

Vegetables

Nuts

Whole grains, such as:

Barley

Bran

Quinoa

Oatmeal

Brown rice

Seeds

Legumes, including peas, beans, and lentils

Other recommendations for improved gut health include:

Increasing consumption of whole foods by adopting the Mediterranean diet

Limiting processed foods

Eating smaller meals

Eating more slowly and chewing food thoroughly

Managing stress

Exercising more

Setting a gut bedtime

Gut health can also be improved by taking probiotics and prebiotics.

Probiotics are “good” bacteria and other microorganisms that reside in the gut and are believed to support a healthy immune system and good digestion. Probiotics can be found in fermented foods, including:

Yogurt

Kefir

Sauerkraut

Kombucha

Pickles that are salt-based

Tempeh

Kimchi

Miso

Prebiotics are dietary fibers that probiotics feed on. They can be found in several high-fiber foods, including:

Leeks

Asparagus

Garlic

Onions

Bananas

Chicory root

The Academy of Nutrition and Dietetics recommends that women aim for 25 grams of fiber per day and men for 38 grams per day.

If you would like to improve your gut health and balance your gut microbiome, you can consult a physician by visiting Flushing Hospital Medical Center’s Ambulatory Care Center. To schedule an appointment, please call (718) 670-5486.

Glucose Tolerance Test

Posted on June 15, 2026 by Xavia Malcolm

A glucose tolerance test is a medical lab test used to measure how effectively our bodies process sugar after a meal. It helps healthcare providers screen for or diagnose conditions such as insulin resistance, prediabetes, type 2 diabetes, or gestational diabetes.

The most common and standard glucose tolerance test is an oral glucose tolerance test (OGTT). However, other screening methods can include a glucose challenge test, used during pregnancy to screen for gestational diabetes, or an intravenous glucose tolerance test, primarily used in research and rarely used as an alternative to OGTT when a patient is unable to process oral glucose.

The Centers for Disease Control and Prevention (CDC) explains that a typical oral glucose tolerance test (OGTT) involves measuring your blood sugar levels before and after consuming a sweet liquid that contains glucose. You will need to fast overnight before the test, after which your blood will be drawn to measure your fasting blood sugar level. Then, you will drink the glucose solution, and your blood sugar levels will be checked again. These measurements typically occur at the 1-hour, 2-hour, and possibly 3-hour marks after drinking the solution.

After testing, you may resume your normal daily activities. Your physician or healthcare provider should receive your lab results in the next few days. Your test results may fall within the following ranges.

Normal – where blood sugar returns to an expected normal range after drinking the glucose solution
Prediabetes – where blood sugar is higher than normal but not high enough to determine a diabetes diagnosis
Diabetes -where blood sugar levels remain highly elevated

If your results show that you have diabetes, your doctor may determine next steps based on how high your blood sugar levels are. They may want to test again to confirm their findings, request additional testing to check for related conditions, or create a treatment plan that may involve lifestyle changes or medications.

Men’s Health Month- Health Screenings for Men

Posted on June 10, 2026 by Patrick Hercules

June is Men’s Health Month. This observance aims to raise awareness about preventable health problems that affect men and boys.

Statistics show men are less likely than women to seek medical attention when something affects their health. Men are also less likely to have preventative screenings and checkups with their healthcare providers. This is a problem as early detection of a medical condition is the best way to effectively treat and manage it.

Additionally, avoiding or delaying checkups or screenings could result in a treatable condition becoming severe and/or fatal.

The U.S. Preventative Services Task Force (USPSTF) publishes a list of recommended, age-specific screening guidelines for men to help them manage their health:

Screenings guidelines recommended for men ages 18-39 include:

Physical examinations

Blood pressure screenings

Cholesterol screenings

Colon cancer screenings

Dental examinations

Prediabetes and type 2 diabetes screenings

Eye examinations

Immunizations

Skin examinations

Infectious disease screenings

Screenings guidelines recommended for men ages 40-64 include:

Physical examinations

Blood pressure screenings

Cholesterol screenings

Colorectal cancer screenings

Prostate cancer screenings

Osteoporosis screening

Lung cancer screening

Infectious disease screening

Immunizations

Eye examinations

Dental examinations

Skin examinations

It is important to visit your healthcare providers regularly, even if you are feeling healthy. These visits can help:

Screen for any medical issues

Encourage a healthy lifestyle

Assess your risk for any future medical problems

Update vaccinations and other preventative care services

Help you get to know your healthcare provider in case of an illness

If you are experiencing any medical problems or would like to receive health screenings, you can schedule an appointment at Jamaica Hospital Medical Center’s Ambulatory Care Center, by calling (718) 206-7001.

Cataract Awareness Month

Posted on June 3, 2026 by Patrick Hercules

June is Cataract Awareness Month, a month that recognizes the importance of educating the public on an eye disease that is the leading cause of vision loss in the United States and the world’s leading cause of blindness.

Most cataracts occur when aging or injury changes the tissue that makes up the eyes’ lens, and proteins and fibers in the lens begin to break down, causing it to become cloudy. Most cataracts develop slowly and don’t disturb eyesight early on, but with time, they will eventually affect a person’s vision.

There are several symptoms of cataracts, including:

Clouded, blurred, or dim vision

Trouble seeing at night

Sensitivity to bright light and glare

The need for brighter light for reading and other activities

Seeing “halos” or streaks that form around lights

Frequent changes in eyeglass or contact lens prescription

Fading or yellowing of colors

Double vision in one eye

There are many types of cataracts, including:

Nuclear cataracts

Cortical cataracts

Posterior subcapsular cataracts

Congenital cataracts

Several factors can increase the risk of cataracts, including:

Increasing age

Diabetes

Getting too much sunlight

Smoking

Obesity

Family history of cataracts

Previous eye injury or inflammation

Prolonged use of corticosteroid medicines

Drinking excessive amounts of alcohol

Ophthalmologists and optometrists diagnose cataracts through a comprehensive eye exam. A healthcare provider will closely examine your eyes for signs of cataracts and assess their severity. They will also ask about your vision, medical history, and if you’re having trouble with everyday tasks because you can’t see as well as before. Tests used to diagnose cataracts include:

Slit lamp exam

Visual acuity test

Cataract surgery is the only way to remove cataracts and restore clear vision. During this surgery, an ophthalmologist removes the clouded natural lens and replaces it with an intraocular lens (IOL). An IOL is an artificial lens that permanently stays in the eye.

No studies have proven how to prevent or slow the growth of cataracts. However, healthcare professionals think several strategies may be helpful, including:

Getting regular eye exams

Quitting smoking

Managing other health problems

Choosing a healthy diet that includes plenty of fruits and vegetables

Wearing sunglasses

Reducing alcohol use

If you’re experiencing cataract symptoms, you can schedule an appointment at Jamaica Hospital Medical Center’s Ophthalmology Center by calling (718) 206-5900.

American Diabetes Alert Day

Posted on March 23, 2026 by Xavia Malcolm

American Diabetes Alert Day is observed each year on the fourth Tuesday in March. The observance was created by the American Diabetes Association to raise awareness of the seriousness of diabetes and highlight the importance of understanding your risk.

According to the Centers for Disease Control and Prevention (CDC), diabetes is the seventh leading cause of death in the United States. Furthermore, the CDC reports that, “More than 40 million Americans have diabetes, and more than 1 in 4 adults with diabetes don’t know they have it.”

Diabetes is a chronic disease that occurs when blood glucose (or blood sugar) levels are too high. This happens because the pancreas does not produce enough insulin to help regulate the amount of sugar that enters the body’s cells. As a result, excess sugar accumulates in the bloodstream.

If diabetes is not managed properly or is left untreated, it can lead to complications and increase the risk of serious health problems. Diabetes complications include:

Damage to the nerves in the body
Kidney problems
Skin problems
Bladder problems
Eye diseases that can lead to blindness
Gum disease
Foot complications that can lead to limb loss
Cardiovascular disease, potentially increasing the risk of hypertension, heart attack, or stroke

Some people are more at risk of developing diabetes than others. You may have an increased risk if you:

Are overweight or obese
Are physically inactive
Have non-alcoholic fatty liver disease
Have a parent or sibling with diabetes
Have ever had gestational diabetes
Are age 45 and older
Are a Hispanic or Latino, African American, American Indian, or Alaska Native person. (The CDC states that some Pacific Islander and Asian American people also have a higher risk.)

Diabetes Alert Day serves as a “wake up call” to pay attention to these risk factors and properly manage your health. If you are at risk of developing diabetes, you should speak with your doctor about ways to improve your health and lower the chances of complications occurring. To schedule an appointment with a doctor at Jamaica Hospital Medical Center, please call 718-206-7001.
