Vision Problems

• Individuals with diabetes may experience vision problems. Diabetic retinopathy occurs when the retina blood vessels are damaged. This condition can lead to partial or total blindness.
  
  

Nerve Damage

• A prolonged excess of sugar in the blood can damage the capillaries that feed nerves. This most often effects the legs and can cause numbness or pain. If untreated, all feeling may eventually be lost in the affected areas. Nerve damage may also affect the digestive system and cause problems such as constipation, diarrhea and vomiting. Men may also be distressed by erectile dysfunction.
  
  

Feet Problems

• Nerves in the feet may also be damaged by diabetes. Infections may occur, and in some cases amputations may be necessary if infections become rampant.
  
  

Kidney Damage

• Diabetes can impair kidney function and over time lead to complete failure of the kidneys. In severe cases, individuals may need dialysis or even possibly a transplant.
  
  

Skin Problems

• Individuals with diabetes are more prone to experience fungal or bacterial infections of the skin.
  
  

Increased Risk of Cardiovascular Disease

• According to the Mayo Clinic, individuals with diabetes are twice as likely to suffer from heart disease or a stroke. Also, diabetes sufferers may develop coronary artery disease or atherosclerosis, which occurs when plaque build-up causes the arteries to narrow (see Resources).
  
  

Other Associated Risks

• The risk of developing Osteoporosis is increased in individuals with diabetes. Also, there is a greater risk for developing Alzheimer's disease.
