owhat is the role of exercise in diabetes?
if perfect sugar is four to six and sugar begins to escape into the blood stream at fifteen ???? does it follow that the intervening window is where the excess sugar stores as fat?
if sugar was constant at five does that mean that you don’t need any exercise-see agatston and the south beach diet
Exercise improves the metabolism of the diabetic in many
ways.There is an increase in number and sensitivity of the insulin receptors. Both these factors control diabetes.There is promotion of delivery of oxygen to the tissues which results in their improved efficiency. Physical exercise improves glucose tolerance in non insulin dependant diabetics and insulin dependant diabetics thereby reduce the drug requirements. Along with diet control it plays a major role in the management of diabetes.

There are a number of reasons that exercise is important. To understand this, a little background on the disease is helpful. Type II diabetes (or non-insulin-dependent diabetes) usually strikes after age 40. It is very prevalent. Nearly one in every 10 Americans has this disorder, which is basically a difficulty in processing sugar. Here is what happens:
Normally, the food you eat goes to your stomach and small intestine. Here it is digested into a sugar called glucose. The glucose then enters your blood and is used by your cells for quick energy or is stored in your liver or muscles for future use. As your blood glucose increases with the food you eat, your pancreas secrets insulin. Insulin is in a sense the "key" that opens your body’s cells to receive glucose from your blood. In people like yourself who have Type II diabetes, the pancreas is not producing enough insulin to unlock the cells, or the cells are not responding normally to the insulin that is produced. So, sugar builds up in the blood and disrupts the metabolic process. This leads to fatigue in the early stages. And if the disease is not controlled, it can cause serious problems involving every tissue of the body — resulting in heart disease, kidney disease, blindness, nerve damage, and leg and foot amputations from gangrene.
Exercise Benefits. Exercise helps to control your diabetes in two ways: First, working muscles use insulin more effectively and require far more glucose (sugar, fuel) than inactive muscles. Therefore, the glucose is less likely to build up as much in the blood. Second, the activity helps reduce weight. For unknown reasons, overweight people use insulin far less effectively than those who are slender (80% of diabetics are overweight). In fact, in many cases losing weight may be all that’s needed to control the problem. In addition to controlling diabetes, exercise decreases the risk of heart disease and lowers blood pressure. This is important since diabetics have a greatly increased likelihood of suffering from cardiovascular diseases.
So, if you exercise regularly (emphasis on regularly) and eat properly, you decrease the problem, and you may be able to reduce your medications or perhaps eliminate them altogether. A word about diet, since it is also critical to your condition. The general dietary guidelines for diabetics are the same as for people who do not have the disease — with a few important exceptions. When, what, and how much you eat are essential to controlling your blood sugar level. You should work with a registered dietitian or your physician to plan a diet that suits your lifestyle and health condition.
Exercise Precautions: Although exercise is essential, you must take some simple precautions. Here are a few pointers adapted in part from The Physician and Sportsmedician, Patient Advisor series:
Aerobic exercise, like walking, swimming and cycling, is recommended . Weight lifting, in addition, is also good for most diabetics. However, since pumping iron can increase blood pressure, you should check this out with your doctor.
Some diabetics must monitor their blood glucose to avoid hypoglycemia (high blood sugar level). Know the signs of hypoglycemia (for example, feeling cold, hunger, weakness, dizziness, sweating, trembling, double vision). Have a snack ready if they occur, such as hard candy, a non-diet soda, or fruit juice. Also, you may have to adjust you insulin dosage to accommodate your activity. Again, check with your doctor on all this.
Buy a good pair of workout shoes. Inspect your feet regularly, and take care to avoid blisters and athlete’s foot. Foot problems are more of a concern for diabetics because of poor circulation often associated with the disease.
Drink plenty of fluids before, during, and after the activity — even if you are not thirsty. Dehydration raises glucose levels in your blood.
Exercise 1 to 2 hours after a meal.. Warm up and cool down with light exercises and stretching. Start your exercise program slowly and build it gradually. Try to exercise for 30-60 minutes a day, about 5 days per week or every day if the activity is quite moderate, like walking. Your exercise can be done in segments; for instance, 10 minutes in the morning, at noon, and in the evening.
Increase your general everyday activity–take stairs instead of the elevator, walk to the store instead of driving, park a short distance from your destination and walk the rest of the way, and so on.
Finally, commit to exercise– it’s one of nature’s best medicine– and try to have fun with it.

glucose escapes into the blood at 15? Huh? No, glucose enters your blood as it’s metabolized. Excess glucose and fat are stored. Maybe you’re confusing it escaping in the urine? When glucose is too high your kidneys filter the excess glucose into urine. Some people’s bodies store fat better than others. Insulin signals the body to store glucose as fat when there’s an excess. In those who have insulin resistance there is usually an excess of insulin and then if there’s an excess of glucose too more glucose will be stored as fat. In the case of type 1 where there’s not enough insulin the body break down it’s fat stores and protein trying to fuel the body…but without insulin it still can’t use the glucose so the blood sugar rises. This is why those who have type 1 lose weight easily and those with type 2 have a hard time losing weight.
