The main signs and symptoms of type 1 diabetes include:
You may also experience:
The onset of type 1 diabetes signs and symptoms is rapid, happening over a matter of days and weeks rather than months. If you, or someone you know, are experiencing these symptoms you must go to your doctor immediately.
If your blood glucose levels are too high for too long, it can lead to a condition called diabetic ketoacidosis (DKA). DKA is most common at diagnosis, and some people with type 1 may only be diagnosed once they’ve gone into DKA.
DKA occurs when a severe lack of insulin means the body cannot use glucose for energy and starts to break down fat instead. Acids called ketones are the by-product of the breakdown of fat and, if left unchecked, can build up in your blood, making it acidic.
The main symptoms of DKA include:
If you are experiencing these symptoms, you must go to hospital immediately. DKA is very serious and can be fatal.
Scientists are currently investigating the genetic and environmental factors that may trigger your immune system to attack the beta cells in your pancreas, causing type 1 diabetes.
All types of diabetes cause blood glucose levels to be higher than normal. Find out about the key differences between the major types.
Find out why people who have one autoimmune condition are at greater risk of developing other types of autoimmune disease.
Our guides can help provide you with information and support in your journey to living well with type 1 diabetes.
