Diabetes mellitus is caused by a relative or absolute loss of insulin that in turn causes a rise in blood glucose levels. It is fatal if untreated. Diabetes may be treated with medications that can increase insulin production, decrease glucose production and/or increase the efficiency of available insulin. If there is no insulin available then patients must be treated with injections of insulin.
Elevated levels of blood glucose along with secondary production of inflammatory proteins lead to destruction or inflammation of the lining of the blood vessels and cardiovascular disease, kidney disease as well as destruction of the retina and eventual blindness. Diabetics also have less resistance to infection.
Research indicates that cannabinoids reduce the inflammatory effects of diabetes and may prevent or delay the onset of the end stage effects of diabetes on the vascular system, the kidneys as well as the retina. In clinical practice, patients better control of their blood sugar. A possible mechanism for this commonly reported effect is cannabis helps patients relax. This in turn lowers circulating levels of catecholamines that raise blood sugar.
Once again mush more research including clinical trials are indicated.
