Diabetes is a metabolism disorder in which the pancreas in the human body fails to produce insulin, or is unable to use the insulin produced in an effective manner. Most of the food we eat is broken into glucose, which is a form of sugar in the blood. When the food we eat is digested, the glucose enters our blood stream and is the main source of energy for the human body. But this glucose cannot enter our cells without sufficient insulin being present in our body. Insulin is a hormone produced by the pancreas and is needed to convert sugar, starch and other food into energy.

After eating, the pancreas automatically releases the required amount of insulin to move the glucose present in our blood to our cells to regulate our blood sugar level. Insufficient secretion of insulin by the pancreas results in excess glucose levels in the blood stream, resulting in diabetes, which eventually damages various organs in the body. A person with diabetes has no control over his blood sugar as his body either does not produce enough insulin, or produces no insulin or has cells that do not respond effectively to the insulin produced by the pancreas. This leads to too much glucose level in the blood stream which eventually damages various organs in the body.

Persons suffering from diabetes show symptoms like fatigue, hazy vision, excessive thirst, weight loss, frequent urination and increase in appetite.
