- Passing urine more often than usual, especially at night
- Increased thirst
- Extreme tiredness
- Unexplained weight loss
- Genital itching or regular episodes of thrush
- Slow healing of cuts and wounds
- Blurred vision
In Type 1 diabetes the signs and symptoms are usually very obvious and develop very quickly, typically over a few weeks. The symptoms are quickly relieved once the diabetes is treated and under control.
In Type 2 diabetes the signs and symptoms may not be so obvious, as the condition develops slowly over a period of years and may only be picked up in a routine medical check up. Symptoms are quickly relieved once diabetes is treated and under control.
