Complications of type 2 diabetes
Diabetes type 2 is a very serious condition. If not treated, it can lead to a number of health problems and complications. Complications of type 2 diabetes are caused by high glucose levels and develop gradually. Sometimes complications may go unnoticed. But eventually, complications can get life threatening. So it’s important to pay attention to the following conditions.
People with diabetes type 2 are more likely to develop cardiovascular problems. If blood glucose levels are not monitored properly, blood vessels can become clogged and narrowed. This may result in a poor blood supply to the heart. A clogged blood vessel in the heart or brain can lead to a heart attack or stroke.
High glucose levels can damage the walls of the tiny blood vessels that nourish the nerves. This can cause tingling, numbness or pain starting at the tips of the toes and fingers and gradually spreading towards legs and arms. If not treated, this can lead to loss of feeling in affected limbs and eventually loss of limbs. If the nerves of the digestive system are affected, it can lead to constipation, diarrhoea, nausea and vomiting.
Diabetes type 2 can cause the tiny blood vessels in the kidneys to become blocked. This will cause the kidneys to work less efficiently. Severe damage to the kidneys can lead to kidney failure and in the worst case, a dialysis treatment or a kidney transplantation can be necessary.
Blood vessels in the eye can become damaged due to high glucose levels in the blood. If not treated, it can damage eye sight seriously potentially leading to blindness. People with diabetes type 2 are advised to have their eyes checked regularly. Diabetes type 2 also increases the risk of other eye diseases such as glaucoma and cataracts.
People with diabetes type 2 often experience problems with their feet, like small wounds that don’t seem to heal. This is because diabetes type 2 affects the blood flow to the feet which reduces the body’s ability to heal wounds. Also, due to nerve damage, it can be more difficult to feel pain from small cuts and bruises.
