Dear Dr. Mo: What is the link between being overweight and developing Type 2 diabetes? Can diabetes be prevented or cured somehow?
Dear reader: First of all it is worth pointing out that diabetes is a chronic condition. For most types (except gestational type) this chronicity means that once it occurs, it stays for life – this is not a disease we can effectively cure with our present knowledge but we can quite successfully manage it.
Before I go into your question, let me first explain the diabetes landscape and basic mechanisms behind it as Type 2 is not the only game in town.
Diabetes occurs either when the pancreas no longer produces enough insulin or when the body cannot effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar.
The danger of diabetes lies in a condition called Hyperglycaemia – raised blood sugar level – which is a common result of uncontrolled/undiagnosed diabetes, which over time causes serious damage to the body, especially to blood vessels and nerves.
Diabetes has its types and these differ in both the ways they start and the ways in which we manage them.
Type 1 Diabetes
This type had previously been known as insulin-dependent, juvenile or childhood-onset diabetes. Here, our pancreas gland becomes deficient in insulin production and there is simply no longer enough of it to properly regulate our blood sugar levels. Management requires daily administration of insulin and this type cannot be prevented with our current understanding as the cause is not known although we do think it is due to the self-inflicting damage to pancreas (process called “auto immune response”).
