Diabetes Q & A

by John A Berger, M.D.

What is type 1 diabetes?

Type 1 diabetes was once called juvenile diabetes. Type 1 diabetes is typically diagnosed in early childhood, although it can also be diagnosed in young adults in rare cases. When a patient has type 1 diabetes, they don't make the insulin that their body needs. Type 1 diabetes isn't preventable.

What is type 2 diabetes?

Type 2 diabetes is most often diagnosed in adults, although it can occur in children as well. It's the most common kind of diabetes by far. Type 2 diabetes occurs when the body does produce insulin but that insulin isn't processed effectively. This leaves type 2 diabetes sufferers with high glucose levels. Although type 1 diabetes can't be prevented, type 2 diabetes is very much preventable in many cases.

What are the signs of diabetes?

Some of the most common signs of diabetes include:

  • Increased hunger
  • Increased fatigue levels
  • Increased thirst
  • Increased frequency of urination
  • Changes in vision, namely blurry vision or trouble focusing the eyes
  • Dry mouth
  • Itchy skin
  • Yeast infections
  • Slow healing cuts on the skin
  • Numbness in the feet
  • Foot pain
  • Strange sweet odor to the breath

What causes type 2 diabetes?

Type 2 diabetes can result from several things. In most cases, a combination of factors come together to cause type 2 diabetes. The uncontrollable risk factors for type 2 diabetes include:

  • Family history of diabetes
  • Race: African-American, Hispanic, Native American, and Asian patients are more likely to develop type 2 diabetes
  • Age: as you age, your risk for type 2 diabetes increases

There are also a number of fully controllable risk factors for type 2 diabetes. These include:

  • Hypertension
  • High cholesterol
  • Obesity
  • Inactive lifestyle
  • Poor eating habits

What is the treatment for diabetes?

Type 1 diabetes patients must take regular insulin, usually through either an insulin pump or through injection therapy. Type 2 diabetes patients may not require a full insulin regimen, especially if their diabetes is in the early stages and is diagnosed quickly. Lifestyle changes are important for diabetes patients. Type 2 diabetes patients may need to make some major changes such as losing extra weight, changing their eating habits, and increasing physical activity levels. There are also medications that can help keep blood sugar levels under control.
