The symptoms of Type 1 diabetes often occur suddenly and can be severe. They include:
- Increased thirst
- Increased hunger (especially after eating)
- Dry mouth
- Frequent urination
- Unexplained weight loss (even though you are eating and feel hungry)
- Fatigue (weak, tired feeling)
- Blurred vision
- Numbness or tingling of the hands or feet
- Loss of consciousness (rare)
The symptoms of Type 2 diabetes may be the same as those listed above. Most often, there are no symptoms or a very gradual development of the above symptoms. Other symptoms may include:
- Slow-healing sores or cuts
- Itching of the skin (usually in the vaginal or groin area)
- Yeast infections
- Recent weight gain
If you suddenly experience symptoms of increased thirst, frequent urination, or unexplained weight loss, your doctor may suspect diabetes. To confirm the diagnosis, a fasting plasma glucose test or a casual plasma glucose test will be performed.
