Diabetes Mellitus is a chronic and complex disease, which can affect the entire body. Diabetes is caused by having too much glucose or sugar in the blood.
How Carbohydrate metabolized?
Carbohydrate is broken down in stomach and glucose is separated and realized in to the blood stream and it is consumed by the body cell once insulin is secreted by pancreas. And the excess of glucose is stored in the liver by converting glucose into glucogen.
If in-fasting and no food consumed then there will be shortage of glucose in blood. Low glucose level means low level of insulin in blood, on seeing this liver convert stored glucogen into glucose and realized into the blood stream to maintain blood glucose level.
The above said all conversions are controlled by insulin secreted by the pancreas. Insulin is a hormone and it is the controlling or commenting signal that controls carbohydrate metabolism and helps to maintain normal blood glucose level in blood.
Any defect in the carbohydrate metabolism causes an increase in blood glucose level in the blood called as diabetes. Diabetes is caused by shortage of insulin secretion or in-effective utilization of insulin (insulin resistance).
Diabetes sign and symptoms
Body system tries to normalize high level of glucose in blood by different means causing some unusual symptoms called as diabetes symptoms.
Some of the most common diabetes symptoms are:
Frequent urination - Frequent urination does not means two or three time urination than normal, but it means doubled or tripled urination than normal.
Frequent or too much thirsty - Frequent thirst means even after drinking enough water, there will be thirst with very short time.
Sudden weight loss or gain - Sudden weight loss or gain will be noted within few day, may be within a month.
Blurred vision - Even after a good night sleep, there is a blurred vision and difficult to concentrate.

Increased fatigue – Even if having the meals in time and have rest as usual, there is a feeling of tired and fatigue.
Poor wound healing – If having hurt which heals very slowly than normal.
Irritability – Mentally feel tired and irritable.
If have many of these diabetes symptoms, then it is advisable to have a blood test to measure glucose level in blood. And if proved positive then it is must to maintain the blood glucose level near normal, because long term of badly maintained blood glucose level may lead to many diabetes complications such as; nerve damage, eye damage, kidney problems, heart attack, brain stroke, erectile dysfunction, depression and amputation.
