Signs and Symptoms of Diabetes
A high blood sugar level can cause several warning signs, including:
- Blurry vision
- Extra thirst
- Repeated urination
- Weight loss
Because type 2 diabetes grows slowly, some people have no symptoms.
Symptoms of type 1 diabetes grow over a short period and people may be very sick by the time they are diagnosed.
After many years, high sugar level in the blood can lead to other major problems. These problems are known as diabetes complications, and include:
- An increased chance of having a heart attack or stroke
- Eye problems, including trouble seeing (especially at night) and light sensitivity
- Sores and infections of the legs or feet, which untreated can lead to amputation
- Damage to nerves in the body, causing pain, tingling and loss of feeling
- Kidney failure
- A weakened immune system, which can lead to more repeated infections
