2. Home glucose monitoring using either a visually read test or a digital readout of the glucose concentration in a drop of blood. Patients can usually learn to use the necessary equipment and perform finger sticks. They keep a daily record of findings and are taught to adjust insulin dosage accordingly. More recent glucose monitoring devices can draw blood from other locations on the body, such as the forearm.
That said, some research does suggest that eating too many sweetened foods can affect type 2 diabetes risk, and with the Centers for Disease Control and Prevention (CDC) estimating that 30.3 million Americans have the disease — and that millions of more individuals are projected to develop it, too — understanding all the risk factors for the disease, including sugar consumption, is essential to help reverse the diabetes epidemic.
Sequelae. The long-term consequences of diabetes mellitus can involve both large and small blood vessels throughout the body. That in large vessels is usually seen in the coronary arteries, cerebral arteries, and arteries of the lower extremities and can eventually lead to myocardial infarction, stroke, or gangrene of the feet and legs. atherosclerosis is far more likely to occur in persons of any age who have diabetes than it is in other people. This predisposition is not clearly understood. Some believe that diabetics inherit the tendency to develop severe atherosclerosis as well as an aberration in glucose metabolism, and that the two are not necessarily related. There is strong evidence to substantiate the claim that optimal control will mitigate the effects of diabetes on the microvasculature, particularly in the young and middle-aged who are at greatest risk for developing complications involving the arterioles. Pathologic changes in the small blood vessels serving the kidney lead to nephrosclerosis, pyelonephritis, and other disorders that eventually result in renal failure. Many of the deaths of persons with type 1 diabetes are caused by renal failure.

Oral Agents. Oral antidiabetic drugs (see hypoglycemic agents) are sometimes prescribed for patients with type 2 diabetes who cannot control their blood glucose with diet and exercise. These are not oral forms of insulin; they are sulfonylureas, chemically related to the sulfonamide antibiotics. Patients receiving them should be taught that the drug they are taking does not eliminate the need for a diet and exercise program. Only the prescribed dosage should be taken; it should never be increased to make up for dietary indiscretions or discontinued unless authorized by the physician.

In this health topic, we discuss hyperglycemic hyperosmolar nonketotic syndrome (HHNS), an extremely serious complication that can lead to diabetic coma and even death in type 2 diabetes. This serious condition occurs when the blood sugar gets too high and the body becomes severely dehydrated. To prevent HHNS and diabetic coma in type 2 diabetes, check your blood sugar regularly as recommended by your health care provider; check your blood sugar more frequently when you are sick, drink plenty of fluids, and watch for signs of dehydration.
