Knowing about Diabetes Type 2 Chronic metabolic disease known as type 2 diabetes is characterized by high blood glucose (sugar) levels. It arises from either inadequate insulin synthesis by the body or from its incapacity to use insulin efficiently. The pancreas secretes the hormone insulin, which aids in the absorption of glucose into cells for energy generation and helps control blood sugar levels. Type 2 Diabetes: What Is It? With type 2 diabetes making up around 90% of cases worldwide, it is the most prevalent kind of the disease. In contrast to type 1 diabetes, which is an autoimmune disease in which the immune system attacks and kills the beta cells in the pancreas that produce insulin, type 2 diabetes usually develops gradually over time and is frequently linked to lifestyle factors like obesity, sedentary behavior, and poor diet. Reasons and Danger Elements Type 2 diabetes has several different causes, most of which are not completely understood. But a number of things influence how it develops, such as: Genetics: A family history of diabetes may make type 2 diabetes more likely to occur. Lifestyle: Unhealthy eating patterns, inactivity, and excess weight-especially abdominal obesity-are important risk factors. Insulin Resistance: Insulin resistance is a condition in which the body's cells lose their sensitivity to the effects of insulin, raising blood sugar levels. Age and Ethnicity: African Americans, Hispanics, Native Americans, and Asian Americans are among the ethnic groups that are more likely to develop type 2 diabetes. The illness also worsens with age.
