Diabetes is of three main types – insulin-dependent diabetes or the Type 1 diabetes, Non-insulin dependent diabetes or the Type 2 diabetes, and gestational diabetes mellitus. A person’s eating habits and viruses can cause Type 1 diabetes. Heredity, obesity, high blood pressure, and lack of proper diet cause Type 2 diabetes, which is very common. The gestational diabetes mellitus is caused as a result of heredity, increased maternal age, fatness and more reasons. It may cause the mother to develop permanent diabetes. This characteristic may get transferred to the child at a later age. There are certain symptoms with the help of which you can detect diabetes. Excessive urination, constant thirst, loss of weight, excessive starvation, nausea, extreme tiredness, infections, irritability and tiredness are some of them. The importance of insulin comes to light when a person suffers from diabetes. Insulin is a hormone that allows blood sugar or glucose to enter body cells. Diabetes affects a person’s capability to make insulin. Due to diabetes, the glucose remains in the blood itself. This high rate of sugar in the blood may cause harm to your eyes, nerves, kidneys, heart and blood vessels. Other than heredity reasons, you can easily avoid Type 2 diabetes by following some simple steps. For those people who are overweight, reduce the rate of consuming food. Overweight people have the risk of developing diabetes. Try to consume grilled or baked food instead of fried food. Cut down on fatty meals. While having food, check its Glycemic Index. While drinking milk, opt for the skimmed milk instead of the full-fat milk. Exercise is a very effective way, which ensures that you stay in a healthy way always.
