What causes type 1 diabetes in otherwise healthy adults?

Question

Hello doctor,

I am 32 years old and have just found out that I have type 1 diabetes. The problem that I do not understand is why, while I was eating well and exercising regularly, never having any serious illnesses, suddenly my immune system began to attack my pancreas?

How can such things happen suddenly when you are healthy throughout your life?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

I am sorry you are going through this because a new diagnosis of type 1 diabetes can feel very confusing and unfair, especially when you have been taking good care of your health. Type 1 diabetes is not often caused by diet, exercise, or anything you did wrong, and it often develops silently over time before it suddenly becomes noticeable.

It is an autoimmune condition causing the immune system to mistakenly attack the beta (insulin-producing) cells in the pancreas, but the exact reason this switch occurs is not fully understood. What we do know is that it usually results from a mix of genetic susceptibility and environmental causes such as certain viral infections or immune system changes, but in many people, there is no clear identifiable trigger at all.

The process can take months or even years without symptoms until enough insulin-producing cells are affected, and then it appears to happen suddenly when blood sugars rise, and symptoms become obvious. It is important to remember that this is not something you caused, and with modern insulin therapy, glucose monitoring, and proper education, many people with type 1 diabetes live full and active lives.

I hope this helps.
