What is Diabetes?


When should we check for type 2 diabetes when we have no symptoms?

Diabetes is a chronic disease in which sugar levels are elevated in the blood. There are many types of diabetes, the most common ones are:

  • Type 2 diabetes – in which there is a resistance to insulin
  • Type 1 diabetes – in which there is an autoimmune deficiency of the hormone insulin.

There are no good and bad types of diabetes; what is important is to have a control individualized to each person.

  1. Age
  2. BMI
  3. Waist circumference
  4. Sedentary lifestyle
  5. Unhealthy eating habits (low in fresh vegetables and fruits)
  6. Other complications such as hypertension, as well as some conditions (such as PCOS)
  7. A previously elevated blood sugar (including gestational diabetes in women)
  8. Having at least one close relative with type 2 diabetes.

Tip: If you have one or more of these factors, consult your physician to evaluate your risk for type 2 diabetes.

You have abnormal sugar levels or HbA1c on your routine blood exam. Now what?

We diagnose diabetes based on three readings: a fasting blood sugar, a sugar level 2 hours post meal and an HbA1c.

Normal people should have an FBS < 100 mg/dL, a sugar 2 hours post meal <140 mg/dL, and an HbA1c <5.7%

People with prediabetes (meaning they are insulin resistant) show FBS between 100 and 125, sugars 2 hours post meal between 140 and 199, and an HbA1c between 5.7 and 6.4%

Diabetes is diagnosed with a fasting blood sugar > 126 mg/dL, a post meal or random sugar > 200 mg/dL, and a HbA1c more than 6.5%

Tip: If one or more of these values are abnormal, consult your doctor for management, and follow with an endocrinologist for individualization of therapy
