Keep your blood pressure under control. People with diabetes are more likely to have high blood pressure than are people who don't have diabetes. Having both high blood pressure and diabetes greatly increases your risk of complications because both damage your blood vessels and reduce blood flow. Try to keep your blood pressure in the range your doctor recommends, and be sure to have it checked at every office visit.
Type I diabetes usually occurs in people who are below the age 20 and that is why it is also called as juvenile diabetes. In this type, the body becomes partially or completely unable to produce insulin. Type I diabetes is an autoimmune disease. In this, your immune system attacks the pancreas from where the insulin is produced, thereby making the pancreas inefficient or unable to produce insulin. Type I diabetes cannot be prevented, it can only be controlled with healthy lifestyle changes.
Abnormal cholesterol and triglyceride levels. If you have low levels of high-density lipoprotein (HDL), or "good," cholesterol, your risk of type 2 diabetes is higher. Triglycerides are another type of fat carried in the blood. People with high levels of triglycerides have an increased risk of type 2 diabetes. Your doctor can let you know what your cholesterol and triglyceride levels are.
