Insulin is a protein-based hormone that is made by the beta cells of the pancreas. Most people know that insulin is the hormone that helps the body’s cells put glucose into the cells for use as cellular fuel. In the absence of insulin, the cells do not have enough biochemical energy so they must use other nutrients in order to function. Without insulin, life-threatening complications can occur due to high blood sugar levels. Insulin and Metabolism When a person eats a meal containing glucose (or any other carbohydrate), the pancreas secretes insulin so that the glucose absorbed by the cells can be used for cellular metabolism. Insulin essential for cell metabolism and, without it, the individual would die. In type 1 diabetics, the pancreas cannot secrete insulin so the blood sugars go higher. The cells do not get enough glucose for cellular metabolism. In type 2 diabetes, there is usually enough insulin secreted; however, the cells are resistant to insulin and glucose cannot get into the cells for cellular metabolism. If diabetes is left unchecked, glucose builds up in the bloodstream and doesn’t get passed along to the cells nor is it stored as glycogen in the liver. This can Continue reading >>

    Where and how to get syringes in FL?
