Type 2 Diabetes Mellitus


Type 2 Diabetes Mellitus is a non- communicable disease with an array of metabolic derangement due to hyperglycemic state. The root cause of it is the insulin resistance state resulting in decreased insulin secretion as well as reduced glucose intake by tissues. Consequently, hepatic glucose production and renal reabsorption of glucose are enhanced. Diabetes mellitus is a chronic disease that requires long-term management to limit further development of its devastating complications, namely nephropathy, retinopathy, neuropathy, and dermatopathy. This disease is not curable but can be managed with antidiabetic medications and lifestyle modifications. The risk factor for diabetes mellitus type 2 is 10 times higher for an individual who has diabetics running in family members. Nonetheless, it is still preventable if precautionary steps are taken earlier.
