Type 2 Diabetes - Causes, Prevention & Treatment

Type 2 Diabetes is a chronic and lifelong condition that is characterized by the inability of the cells in your body to respond adequately to insulin; the hormone that brings glucose from the blood to the cells where it is used for energy. Due to the inability of the cells to utilize the sugar in the insulin, blood sugar levels rise and the body is forced to rely on alternative energy sources in muscles and internal organs, and other parts of your body.

How is Type 2 Diabetes Caused?

  • The Pancreas is responsible for the production of a hormone called insulin that plays a crucial role in the conversion of glucose into energy.
  • Glucose is a type of sugar that is obtained from the food consumed and when the cells are not able to properly harness this energy from the insulin, blood sugar builds up leading to a variety of problems.
  • Scientists have offered several explanations for why this happens and a genetic factor might be present in some cases.
  • The Primary Causes of Type 2 Diabetes include the body’s development of insulin resistance where the cells do not respond properly to the hormone or the body’s inability to produce enough insulin to break down blood sugar.

How is Type 2 Diabetes Diagnosed?

There are several diagnostic tests with the help of the symptoms, if any, can help in the detection of Type 2 Diabetes.

  1. Glycated Hemoglobin (A1C) Test : Type 2 Diabetes diagnosis is usually done with the help of this blood test that indicates a person’s average blood sugar levels calculated for a period of around two or three months.
  2. Random Blood Sugar Test : Regular checkups to measure sugar levels in the blood can also help diagnose Type 2 Diabetes if the results are abnormally high and especially when there are accompanying symptoms.
  3. Fasting Blood Sugar Test : A blood sample is taken after the individual fasts for at least eight hours overnight to negate the influence of recent meals and food intake. Two tests usually needed to diagnose Type 2 Diabetes.
  4. Oral Glucose Tolerance Test (OGTT) : A liquid is administered to the individual and blood sugar levels are monitored over the next few hours. It is not very common except in the cases of pregnant women.
    Routine screening is recommended for all those over the age of 45 and especially those who are overweight.

Type 2 Diabetes Treatment

Diabetes mellitus treatment is often a mix of both lifestyle changes as well as medication. It is best to consult an Endocrinologist to ascertain the best course of treatment.

  • Lifestyle Changes : Treatment for Type 2 Diabetes must necessarily include weight loss and healthy eating habits.

  • Medication : When lifestyle changes do not achieve the desired results, medication is a must. Metformin is usually considered the best medicine for Type 2 Diabetes which helps the body respond better to insulin. Other medications also include Meglitinides that boost insulin production, insulin shots, and also DPP-4 inhibitors that directly lower blood sugar levels.
