It is important to sort out prediabetes, because, most people with prediabetes are likely develop type 2 diabetes within 10 years if adequate measures are not taken.

Causes of type 2 diabetes

Heart and blood vessels: Cardiovascular complications like chest pain (angina), heart attack, stroke, high blood pressure are two to four times more common in people with diabetes.

Nervous system (neuropathy): It can cause tingling, numbness, burning or pain that usually begins at the tips of the toes or fingers and gradually spreads upward. For men, there may be chance of erectile dysfunction.

Kidney (nephropathy): In diabetes, the filtering capacity of kidney is lost which may lead to kidney failure or irreversible end-stage kidney disease.

Eye: Diabetes is one of the most common cause of blindness. There is also increased risk of cataracts and glaucoma in diabetic patients.

Foot: Diabetic foot develops as a result of nerve damage or reduced blood flow to the lower extremity. It is a very severe complication. If proper care is not taken, severe damage may lead to toe, foot or even leg amputation.

Skin and mouth: Diabetic patients often develop bacterial and fungal infections of skin and mouth.

How to diagnose

Random blood sugar test: A random blood sugar level of 200 mg/dL (11.1 mmol/L) or higher suggests diabetes.

Fasting blood sugar test: A blood glucose level of 126 mg/dL (7 mmol/L) or higher on two separate occasions indicates diabetes mellitus.

Oral glucose tolerance test

Glycated hemoglobin (A1C) test: This blood test reflects average blood sugar level for the past two to three months of the patient.

I am a physician by profession. I dream to work on medicine in the near future. I have completed my residency three years back. Now, I am planning to obtain MRCP. This is very hard exam and surely, I am always scared of it. I have also decided to do my specialization on cardiology. Before medical school, I never thought that our heart could be so complex! So pray for me. I usually don't have enough time to write due to my studies. But whenever I get time I love to write. I write on medical related issues. I try to make it simple for you.
