Everything You Need to Know About Diabetes
1. The Different Types
Diabetes is a widespread disease that involves either the lack of insulin production (Type 1 Diabetes) or an inability of the body to use insulin, known as insulin resistance (Type 2 Diabetes). Insulin is a vital hormone secreted by the beta cells of an organ called the pancreas. It increases in response to blood glucose levels when food is ingested, allowing the body’s tissues to take up the glucose to use as energy. This causes the blood glucose to go back to its normal level.
Type 1 diabetes, also known as juvenile-onset or insulin-dependent diabetes, makes up five to ten percent of those affected by the disease. In Type 1 diabetes, your immune system attacks and destroys cells which produce insulin, the hormone that allows your body to convert glucose into energy. Symptoms include thirst, hunger, fatigue, frequent urination, weight loss, tingling or numbness in the feet, and blurred vision.
Type 2 diabetes, also known as adult-onset or non-insulin-dependent diabetes, appears during adulthood. In this form, the body develops insulin resistance, meaning that the body is not able to use insulin to produce energy from glucose, resulting in increased glucose levels. This can lead to the pancreas producing less than the required amount of insulin, leading to an insulin deficiency. Common symptoms for type 2 diabetes are excessive thirst, frequent or increased urination, excessive hunger, fatigue, blurry vision, and sores that won’t heal.
