Understanding Diabetes
This section provides a concise overview of diabetes, focusing on its definition, the critical relationship between blood sugar and insulin, and an introduction to type 2 diabetes.
What Is Diabetes
Diabetes is a chronic health condition where the body is unable to properly process glucose, leading to elevated blood sugar levels. Persistent high blood sugar is a hallmark sign of diabetes and can lead to a range of health complications.
Blood Sugar and Insulin Relationship
Blood sugar, or glucose, is the body's primary energy source, obtained from the food consumed. Insulin, a hormone produced by the pancreas, is essential for glucose to enter cells and generate energy. In diabetes, this process is disrupted, and blood sugar levels can become abnormally high or low, a condition known as hyperglycemia or hypoglycemia, respectively.
Type 2 Diabetes Overview
Type 2 diabetes, the most common form of the disease, occurs when the body becomes insulin resistant, meaning cells don't respond typically to insulin. Over time, the pancreas may also produce less insulin. Type 2 diabetes is associated with several risk factors, including obesity, inactivity, and family history. If poorly managed, it can lead to serious complications such as heart disease, kidney failure, and vision loss. Management typically includes lifestyle changes, medication, and monitoring blood sugar levels.
