COMPLICAÇÕES CRÔNICAS DO DIABETES MELLITUS TIPO 2

Abstract

Diabetes mellitus is defined as a chronic non-communicable disease (NCD), being a syndrome characterized by persistent hyperglycemia, resulting from metabolic disorders, which may occur due to the destruction of insulin-producing beta cells or resistance to insulin action. The increase in plasma glucose occurs due to defects in the secretion and/or action of insulin produced by the pancreas, and can be subdivided into three main types: Type 1 Diabetes mellitus (autoimmune), Type 2 Diabetes mellitus (insulin resistant) and Diabetes gestational mellitus. Diabetes is characterized by multiple complications, acute and chronic (divided into microvascular and macrovascular), which constitute an important cause of early mortality. Chronic microvascular complications are associated with specific injuries caused by difficulty in passing blood to the endothelium. This obstruction occurs due to chronic hyperglycemia that triggers endothelial inflammation, resulting in the production of advanced glycolysis products, leading to oxidative stress, inflammation and the appearance of microthrombi, making this passage difficult. Macrovascular complications, in addition to hyperglycemia, are also related to problems such as dyslipidemia, systemic arterial hypertension and smoking. Such factors can lead to stroke, acute myocardial infarction and peripheral arterial obstructive disease. This work proposes a critical review of the existing literature on the chronic complications of Type 2 Diabetes mellitus, highlighting screening, prevention and treatment measures. It is concluded that technical and clinical knowledge about the pathophysiology and alternative interventions is essential for the immediate and comprehensive care of patients with Type 2 Diabetes mellitus, as well as the prevention of its chronic complications.
