What is a type 2 diabetes?Type 2 diabetes – Also know as non-insulin-dependent or adult-onset. The body produces insulin but the cells fails or becomes ineffective to use insulin leading to increase in the blood sugar level of the body causing diabetes. The high level of glucose in the body slowly destroys the body’s organs such as eyes, kidneys, nerves and blood vessels. Obesity and lack of physical inactivity is the main cause of type 2 diabetes. Diagnosis of this type is very difficult; symptoms are same as that of Type 1 diabetes. To prevent type 2 diabetes and its complications, people should maintain healthy body weight. Physical activities should be included in the daily routine. Regular exercise for at least 30 minutes will help to control weight and diabetes. How is Type 2 diabetes treated? In Type 1 diabetes people need insulin whereas people who are suffering from type 2 diabetes are treated with oral medications as insulin is already produce by the body and only need to be use effectively. The pills are insulin free. Oral medications such as metformin, sulfonylureas, alpha-glucosidase inhibitors, Thiazolidinediones, Dipeptidyl peptidase-4 (DPP-4) inhibitors and many others are use to make the insulin that is already in the body to act in a more effective way. In some cases, patients were treated and asked to take insulin. Insulin can either be injected with a syringe in the body, several times a day, or else it is delivered via an insulin pump.Type 2 diabetes is the most common form of diabetes. During the past few years, the number and percentage of people with diabetes has increased and the reasons are lack of physical activities and overweight. However, type 2 is related to age and typically develops after 40 years of age, but it is seen that young people are also facing the same problems as obesity increasing and physical activity is decreasing in these age groups. Diabetes if left untreated can lead to a number of damaging complications such as heart attacks, strokes, blindness, kidney failure, nerves and blood vessel damage, impotence in men and so on. There are ways of preventing type 2 diabetes, or one can delay its onset if one takes some strong measures. Medicines should be supported by a healthy diet, regular physical activity, maintaining a normal body weight and avoiding tobacco use or any other drugs will help people to avoid many of the complications caused by diabetes. It is seen that people with impaired glucose tolerance, lifestyle interventions were at least as effective in preventing or delaying type 2 diabetes.
