WHAT IS DIABETES

A disease which occur by high levels of sugar in the blood is called Diabetes. To know about diabetes, it is important that we first understand the normal procedure by which food is broken down and used by the body for energy. Many process occur when food is digested:
Sugar which is called glucose enters the blood. It is a source of fuel for the body.
An organ that we called the pancreas makes insulin. The work of insulin is to send glucose from the bloodstream into muscle, fat, and liver cells, where it can be used as a fuel.
People with diabetes have high blood sugar. This is because:
Pancreas of these peoples does not make enough insulin
Muscle, fat, and liver cells of these people do not respond to insulin normally
There are three major types of diabetes:
Type 1 diabetes is usually diagnosed in childhood. Most patients are diagnosed when they are older than age 20. By this disease, the body make little or no insulin. Injections of insulin are necessary.We do not know the exact cause of this disease. Genetics, autoimmune, and viruses, problems may play a role.
Type 2 diabetes It is more common than type 1. It makes up most cases of diabetes. It mostly occurs in adulthood, but youngblood people are increasingly diagnosed with this disease. The pancreas of these people does not make enough insulin to keep the glucose level of the blood normal, because the body does not respond good to insulin. Most people with type 2 diabetes do not know they have it, although it is a very serious condition. Type 2 diabetes is more common due to failure of exercise.
Gestational diabetes It is high blood glucose which develops at any time when thewoman is pregnant who does not have diabetes.Those women who have gestational diabetes are at high risk of cardiovascular disease and type 2 diabetes later in life.
