Diabetes Doctor in Dombivli Diabetes is basically a condition that leads to higher levels of sugar in the blood than is normal. Diabetes occurs when your body cannot either make insulin or is unable to utilize the insulin that is made within it. Insulin is the hormone that allows your body to ingest the sugar that you consume, which is then converted to energy by the body. In concise, there are two types of diabetes, Type 1 & Type 2 diabetes. In type 1 Diabetes, often called juvenile diabetes, the body is unable to produce insulin. This is because the body’s own immune cells attack the islets of the pancreas that produce insulin. In type 2 diabetes. the body can produce some amounts of insulin, but cannot utilize the insulin as required. Type 2 diabetes is often called adult diabetes, but can show up in ages below 35 as well.
