Diabetes


Diabetes mellitus is a condition in which the body either does not produce enough, or does not properly respond to, insulin, a hormone produced in the pancreas. Insulin enables cells to absorb glucose in order to turn it into energy in to the body. In diabetes, the body either fails to respond to its own insulin, does not make enough insulin, or both. This causes glucose to accumulate in the blood, often leading to various complications. There are 2 types of diabetes. Type 1: Results from the body's failure to produce insulin, and Type 2: Results from Insulin resistance, a condition in which cells fail to use insulin properly.The immune system is affected when levels of glucose (blood sugar) rise above normal.

Common symptoms of diabetes include:
Excessive thirst and appetite
Increased urination

Unusual weight loss or gain

Fatigue

Nausea, perhaps vomiting
