Some diabetes symptoms are common to both type 1 and type 2 diabetes. Each has its own particular symptoms.
The main symptoms of diabetes common to both types are:
- feeling very thirsty
- urinating frequently, particularly at night
- feeling very tired
- weight loss and loss of muscle bulk
Many people have type 2 diabetes for years without realising because the early symptoms can be mild.
Visit your GP as soon as possible if you think you have diabetes. Early diagnosis and treatment may reduce your risk of developing complications later on.
Other symptoms of diabetes can include:
- itchiness around the vagina or penis, or regular bouts of thrush (a yeast infection)
- blurred vision that is caused by the lens of your eye becoming very dry
- cramps
- constipation
- skin infections
Not everyone will experience the above symptoms, and they are not usually severe in those who do get them.

Hyperglycaemia (high blood glucose)
Type 2 diabetes develops when the pancreas (a large gland behind your stomach) is unable to produce enough insulin to control your blood glucose level, or when the body's cells don't respond properly to insulin that is produced.
Due to the lack of insulin or its inability to regulate blood glucose, your blood glucose levels may become very high.
Hyperglycaemia can occur for several reasons, including eating too much, being unwell and not taking enough diabetes therapy.
The main symptoms of diabetes are due to hyperglycaemia. They include:
- extreme thirst
- a dry mouth
- blurred vision
- drowsiness
- a need to pass urine frequently
