Diabetes mellitus is a collection of metabolic illnesses defined by hyperglycemia caused by abnormalities in insulin secretion, insulin action, or both. Diabetes' persistent hyperglycemia is connected with long-term damage, dysfunction, and failure of multiple organs, particularly the eyes, kidneys, nerves, heart, brain, and blood vessels. Diabetes is caused by a number of pathogenic mechanisms. These range from autoimmune death of the pancreatic-cells, resulting in insulin insufficiency, to metabolic irregularities and inflammation, resulting in insulin resistance. According to recent studies, CBD can help with diabetes, and cannabis treatment may be beneficial for both type 1 and type 2 diabetes.
