The Difference between Type 1 and Type 2 Diabetes

Diabetes is a chronic disease that occurs when the body doesn’t produce enough insulin or can’t use the insulin it produces effectively.

There are two main types of diabetes: type 1 and type 2.

Type 1 and type 2 diabetes have similar names, however, they are different diseases with distinctive causes.

A key difference between type 1 and type 2 diabetes is type 1 is caused by an autoimmune reaction and develops early in life. Type 2 diabetes develops over several years and is related to lifestyle factors such as being inactive and carrying excess weight, and is usually diagnosed in adults.

Type 1 diabetes is believed to be caused by an autoimmune reaction where the immune system attacks and destroys the insulin-producing beta cells in the pancreas, mistaking them for foreign invaders. After the beta cells are destroyed, the body can no longer produce insulin.

Researchers are unsure why the immune system attacks the body’s cells. They believe it may be due to genetic and environmental factors, such as being exposed to viruses.

People who have type 2 diabetes have an insulin resistance. The body can still produce insulin but is unable to use it effectively.

Researchers aren’t sure why some people become insulin-resistant and others don’t, but several lifestyle factors may contribute to it, such as being inactive and carrying excess weight.

Other genetic and environmental factors may also play a role. When a person develops type 2 diabetes, the pancreas will overcompensate by producing more insulin. Because the body can’t effectively use the insulin, glucose accumulates in the bloodstream.

Risk factors for type 1 diabetes are less clear than risk factors for type 2 diabetes.

The known risk factors for type 1 diabetes include:

  • Family history
  • Age

Risk factors for type 2 diabetes include:

  • Having prediabetes or slightly elevated blood sugar levels
  • Carrying excess weight or having obesity
  • Having a lot of belly fat
  • Being physically active less than three times a week
  • Being over the age of 45
  • Having had gestational diabetes
  • Giving birth to a baby weighing more than nine pounds
  • Being Black, Hispanic or Latino, American Indian, or Alaska Native due to structural inequities contributing to health disparities
  • Having an immediate family member with type 2 diabetes
  • Having polycystic ovary syndrome (PCOS)

If not managed properly, type 1 and type 2 diabetes can lead to symptoms that can include:

  • Urinating frequently
  • Feeling very thirsty and drinking a lot of fluids
  • Feeling very hungry
  • Feeling very fatigued
  • Having blurry vision
  • Having cuts or sores that don’t heal properly
  • Having very dry skin
  • Having more infections than usual

People with type 1 and type 2 diabetes can also experience irritability, mood changes, and unintentional weight loss.

Unfortunately, type 1 diabetes can’t be prevented. However, it is possible to lower the risk of developing type 2 diabetes through lifestyle changes that include:

  • Maintaining a moderate weight
  • Working with a healthcare provider to develop a healthy weight-loss plan, if you are overweight
  • Increasing activity levels
  • Eating a balanced diet and reducing the intake of sugary foods and overly processed foods

If you are experiencing diabetes symptoms, you can call to schedule an appointment with an endocrinologist at Jamaica Hospital Medical Center’s Ambulatory Care Center at (718) 206-7001.

What is Pediatric Diabetes?

Approximately 10% of all Americans have diabetes, with an increasing number of these cases occurring in children and teenagers under the age of 20. Diabetes that occurs within this age range (referred to as pediatric diabetes) usually presents as type 1 diabetes, which causes the body to stop producing insulin. However, type 2 diabetes, which causes insufficient insulin production and causes cells to absorb less sugar from the bloodstream, has begun to account for more of these cases over time.

According to Dr. Hariram Ganesh, a pediatric endocrinologist at Forest Hills Pediatrics, increasing rates of obesity and economic factors are largely to blame for the increased prevalence of pediatric type 2 diabetes.

“Rising obesity rates have caused rates of type 1 and type 2 diabetes in children to even out,” said Dr. Ganesh. “Junk food is much cheaper and more accessible than healthy options. Many families would rather spend a dollar on fast food than 60 dollars on something healthy at the grocery store. “

Children with prediabetes may exhibit certain signs, such as excessive thirst and the frequency with which they need to use the bathroom. Additionally, black marks may occur around the neck, armpits, groin, or other parts of the body due to abnormally high insulin levels. Some other signs you may notice include:

  • Yellow, brown, or red patches of skin
  • Hardened or thickened skin on the fingers or toes
  • Blisters (in rare cases)
  • Skin infections or rashes

If you notice any of these signs, you should bring your child to your primary physician as soon as possible. They can help determine whether your child’s symptoms warrant a referral to an endocrinologist or are indicative of a less severe problem.

While neither type 1 nor type 2 diabetes has a cure, both are treatable. For children with type 2 diabetes, an initial plan of three to six months of dietary changes and exercise coupled with medication may help manage the condition. In cases of type 1 diabetes, however, treatment options are more limited.

“Type 1 primarily involves insulin dependence and cannot be managed with diet and exercise alone,” said Dr. Ganesh. “Even if a child loses weight, they’ll continue to need insulin. Otherwise, they may end up in the hospital.”

Still, Dr. Ganesh emphasizes the importance of diet and exercise, regardless of any diabetes diagnoses your child may or may not have received.

“Diabetes is just one problem among many related to childhood obesity, and in many cases, a diagnosis may only be a matter of time. Parents should make a point to emphasize a healthy diet and physical activity for their children, whether that involves playing with them or finding a local place for them to regularly participate in physical recreation,” said Dr. Ganesh.

If your child is exhibiting signs that may be indicative of prediabetes, schedule an appointment at Jamaica Hospital Medical Center’s Ambulatory Care Center now by calling (718) 206-7001.
