"Normalize Your Blood Sugar" Diabetes is a chronic, often debilitating and sometimes fatal disease, in which the body either cannot produce insulin or cannot properly use the insulin it produces. Insulin is a hormone that controls the amount of glucose (sugar) in the blood. Diabetes leads to high blood sugar levels, which can damage organs, blood vessels and nerves. The body needs insulin to use sugar as an energy source. It is a situation where the sugar level of the blood goes beyond normal. Diabetes could be very deceptive in the sense that one may not feel sick as the blood sugar rises higher than normal, but rising sugar levels can damage blood vessels in no time. Blood vessels are to the body what fuel hoses are to a vehicle. Imagine them being damaged. Diabetes is a defect in the body’s ability to convert glucose (sugar) to energy. Glucose is the main source of fuel for our body. When food is digested it is changed into fats, protein, or carbohydrates.
