Unlike type 1 diabetes which produces symptoms that cannot be ignored, the symptoms of type 2 diabetes often develop gradually, may be vague in nature and often go unnoticed.
The most common symptoms associated with type 2 diabetes include:
- Increased fatigue
- Extreme hunger
- Excessive thirst
- Frequent urination (especially the need to get up during the night to pass urine)
- Blurred vision
- Irritability
- Weight loss
- Frequent infections (especially urinary tract infections, boils, and fungus infections)
- Erectile dysfunction (impotence)
- Slow healing of cuts and sores
Many people with type 2 diabetes don't know they have it. Others find out only by having a routine screening blood sugar performed. The American Diabetes Association (ADA) recommends all adults have routine diabetes screening beginning at age 45, or younger if at high risk.
