Diet. In general, the diabetic diet is geared toward providing adequate nutrition with sufficient calories to maintain normal body weight; the intake of food is adjusted so that blood sugar and serum cholesterol levels are kept within acceptable limits. Overweight diabetic patients should limit caloric intake until target weight is achieved. In persons with type 2 diabetes this usually results in marked improvement and may eliminate the need for drugs such as oral hypoglycemic agents.
Impaired glucose tolerance (IGT) and impaired fasting glycaemia (IFG) refer to levels of blood glucose concentration above the normal range, but below those which are diagnostic for diabetes. Subjects with IGT and/or IFG are at substantially higher risk of developing diabetes and cardiovascular disease than those with normal glucose tolerance. The benefits of clinical intervention in subjects with moderate glucose intolerance is a topic of much current interest.
Feeling famished all the time? Your body could be trying to tell you that something’s up with your blood sugar. Many people with diabetes experience extreme hunger when their condition is unmanaged, thanks to high blood sugar levels. When your body can’t effectively convert the sugar in your blood into usable energy, this may leave you pining for every sandwich or sweet you see. And if you’re looking for a filling snack that won’t put your health at risk, enjoy one of the 25 Best and Worst Low-Sugar Protein Bars!
The progression of nephropathy in patients can be significantly slowed by controlling high blood pressure, and by aggressively treating high blood sugar levels. Angiotensin converting enzyme inhibitors (ACE inhibitors) or angiotensin receptor blockers (ARBs) used in treating high blood pressure may also benefit kidney disease in patients with diabetes.
Type 2 diabetes was also previously referred to as non-insulin dependent diabetes mellitus (NIDDM), or adult-onset diabetes mellitus (AODM). In type 2 diabetes, patients can still produce insulin, but do so relatively inadequately for their body's needs, particularly in the face of insulin resistance as discussed above. In many cases this actually means the pancreas produces larger than normal quantities of insulin. A major feature of type 2 diabetes is a lack of sensitivity to insulin by the cells of the body (particularly fat and muscle cells).
To measure blood glucose levels, a blood sample is usually taken after people have fasted overnight. However, it is possible to take blood samples after people have eaten. Some elevation of blood glucose levels after eating is normal, but even after a meal the levels should not be very high. Fasting blood glucose levels should never be higher than 125 mg/dL. Even after eating, blood glucose levels should not be higher than 199 mg/dL.
According to the Mayo Clinic, doctors may use other tests to diagnose diabetes. For example, they may conduct a fasting blood glucose test, which is a blood glucose test done after a night of fasting. While a fasting blood sugar level of less than 100 milligrams per deciliter (mg/dL) is normal, one that is between 100 to 125 mg/dL signals prediabetes, and a reading that reaches 126 mg/dL on two separate occasions means you have diabetes.
