Type 2 diabetes is the most common form of diabetes. It is a condition in which the body is unable to make enough insulin, and the insulin produced by the body does not work well. When this happens, the glucose level in the blood rises and leads to serious medical problems. Symptoms of high blood sugar include frequent urination, increased thirst and increased hunger. Diabetes, if not treated properly, can cause long-term complications like neuropathy (nerve damage), nephropathy (kidney damage), eye damage (retinopathy), foot problems and also a higher risk of developing heart diseases.
