Diabetes is a chronic metabolic disorder in which the body cannot metabolize carbohydrates, fats, and proteins because of defects in insulin secretion and or action. The criteria for diagnosis is casual plasma glucose 200mg/dl or greater or fasting plasma glucose 126mg/dl or greater or a two-hour plasma glucose oral tolerance test of 200mg or greater.
Diabetes develops when the body cannot produce or use insulin, an essential hormone made in the pancreas. Insulin helps move glucose (a form of sugar) from the blood into the cells of your body.
When glucose builds up in the bloodstream, blood glucose (or blood sugar) rises, causing a condition known as hyperglycemia. When blood glucose goes too high, people experience a variety of symptoms.
The most common symptoms include:
1. Increased thirst
2. Frequent urination
3. Weight loss
4. Increased hunger
5. Blurred vision
