Type 2 diabetes results when the body is unable to produce the amount of insulin it needs to convert food into energy or when it is unable to use insulin appropriately. Sometimes the body is actually producing more insulin than is needed by a person to keep blood glucose in a normal range. Yet blood glucose remains high, because the body's cells are resistant to the effects of insulin. Physicians and scientists believe that type 2 diabetes is caused by many factors, including insufficient insulin and insulin resistance. They increasingly believe that the relative contribution each factor makes toward causing diabetes varies from person to person.
About Diabetes, Type 2: Type 2 diabetes is characterized by "insulin resistance" as body cells do not respond appropriately when insulin is present. This is a more complex problem than type 1, but is sometimes easier to treat, since insulin is still produced, especially in the initial years. Type 2 may go unnoticed for years in a patient before diagnosis, since the symptoms are typically milder (no ketoacidosis) and can be sporadic. However, severe complications can result from unnoticed type 2 diabetes, including renal failure, and coronary artery disease. Type 2 diabetes was formerly known by a variety of partially misleading names, including "adult-onset diabetes", "obesity-related diabetes", "insulin-resistant diabetes", or "non-insulin-dependent diabetes" (NIDDM). It may be caused by a number of diseases, such as hemochromatosis and polycystic ovary syndrome, and can also be caused by certain types of medications (e.g. long-term steroid use). About 90-95% of all North American cases of diabetes are type 2, and about 20% of the population over the age of 65 is a type 2 diabetic. The fraction of type 2 diabetics in other parts of the world varies substantially, almost certainly for environmental and lifestyle reasons. There is also a strong inheritable genetic connection in type 2 diabetes: having relatives (especially first degree) with type 2 is a considerable risk factor for developing type 2 diabetes. The majority of patients with type 2 diabetes mellitus are obese - chronic obesity leads to increased insulin resistance that can develop into diabetes, most likely because adipose tissue is a (recently identified) source of chemical signals (hormones and cytokines).
Known as gurmar, or “sugar destroyer,” in Aryuvedic medicine, Gymnema has consistently shown benefits in patients with diabetes. The most active part of Gymnema seems to be gymnemic acids, and many products list the percentage each capsule contains. Analyses of the herb for diabetes have shown it may be helpful in lowering high blood sugar levels. It can delay glucose absorption from the intestine. It was shown to regenerate pancreatic tissues, allowing more insulin to be produced, and help regulate insulin secretion. It also increases the utilization of glucose by the cell, reducing insulin resistance and decreasing appetite, especially for sweets. I usually use it in capsules, or in liquid form in some patients. Due to Gymnema having a very similar shape to glucose, it can fit into the taste bud receptors for sugar; it thus has unbelievable power to actually prevent the taste of sweets in the mouth for up to 1.5 hours. When I have a patient who is still struggling to not eat cake and cookies and so forth at parties or celebrations (or just in general), I will give her a tincture of Gymnema sylvestre. This is one of my favorite herbs for diabetes. In capsule form doses of 400 to 2,400 mg a day are recommended.
