Diabetes Q & A

What is Diabetes?

Blood sugar (glucose) is used by your body as a source of energy. When you consume sugar and foods that turn to sugar inside your body, your pancreas releases the insulin hormone to ensure your blood sugar levels remain in a safe range. Your pancreas is a small organ located near your stomach that secretes the insulin hormone to help direct excess blood sugar out of your bloodstream and into your cells to be used for energy.

When your body can’t produce insulin or when your cells can’t properly respond to it, your blood sugar levels rise. High blood sugar levels can turn to Diabetes over time.

What are the symptoms of Diabetes?

Diabetes can come along with many problematic symptoms, including:

  • Fatigue
  • Irritability
  • Frequent urination
  • Vision complications
  • Unexplained weight loss
  • Excess thirst and hunger

Many diabetics are more prone to getting infections, such as skin, vaginal, or gum infections.

What are the different types of Diabetes?

Diabetes is categorized into different types.

Type 1 Diabetes

Type 1 Diabetes isn’t as common and is often referred to as an autoimmune condition. Your immune system usually attacks and fights off harmful viruses and bacteria, but if you have type 1 Diabetes, your immune system starts attacking the cells of your pancreas that produce the insulin hormone necessary to keep your blood sugar levels in check.

Type 2 Diabetes

Type 2 Diabetes is more prevalent and happens when your body doesn’t produce enough insulin or doesn’t respond correctly to insulin, leading to high blood sugar levels.


PreDiabetes is essentially a warning signal, like a beacon, indicating that your blood sugar levels are higher than average, but not high enough to be considered Diabetes. Over time, preDiabetes can cross the threshold into type 2 Diabetes.
