The symptoms of diabetes occur because the lack of insulin means glucose stays in the blood and isn't used as fuel for energy.
Your body tries to reduce blood glucose levels by getting rid of the excess glucose in your urine.
Typical symptoms include:
- feeling very thirsty
- passing urine more often than usual, particularly at night
- feeling very tired
- weight loss and loss of muscle bulk
