Not everyone with diabetes has symptoms. About one in five older adults with type 2 diabetes do not know they have the condition. Even without symptoms, people with diabetes have a high risk of developing serious health problems.
Warning Signs and Symptoms of Diabetes
- Increased thirst or hunger
- Frequent urination (sometimes as often as every hour)
- Unusual weight loss or weight gain
- Feeling very tired or low on energy
- Wounds or foot sores that heal slowly
- Numbness or tingling in the feet or hands
- Confusion or depression
- Sexual problems
Regular screening with blood glucose tests is the best way to determine if you have diabetes or are at risk for developing it. Early detection is important for your health. Starting treatment early can help prevent serious complications later.
