In Type 2 diabetes, the body cells are unable to use insulin properly (insulin resistance). This causes glucose (sugar) to accumulate in the blood stream.

Symptoms

The symptoms come on gradually but many people with type 2 diabetes have no symptoms and are diagnosed after a blood glucose test. It occurs more frequently in people who have a family history of diabetes, are over 50 years, are overweight and rarely exercise. Symptoms include:

• Feeling tired
  
• Passing urine frequently
  
• Feeling constantly thirsty
  
• Blurred vision
  
• Itching of the skin or genital area
  
• Slow healing infections
  
• Numbness and tingling in hands or feet
  

• In many people with type 2 diabetes, healthy eating and regular exercise can control blood glucose levels.
  
• The eating and exercise plan a doctor or dietitian may suggest depends on the persons age, lifestyle and overall health.
