The symptoms of type 2 diabetes are sometimes not noticed and may develop slowly. It may take years after the disease has developed before some people are diagnosed with it. The symptoms may occur in people who do not suspect diabetes. There are those who aren't diagnosed until they suffer serious problems such as heart or vision problems. It is important that diabetes be diagnosed early so complications do not start to develop and treatment becomes more difficult. If you have one of more of these symptoms you should see a doctor.
Thirst and Urination
Excess sugar will build up in the bloodstream, depleting fluid from tissues in the body. This depletion causes an increase in thirst and subsequently more urination than usual, the Mayo Clinic explains.
Increased Appetite
Untreated diabetes can result in lost energy because there is not enough insulin to move sugar into the body's cells, muscles and organs. Hunger intensifies as a result.
Frequent Infections
The body has a difficult time resisting infections when affected by type 2 diabetes. There may be recurring infections of the skin, gums or bladder. Sores and bruises will heal more slowly than usual. There may be darkened areas or patches on the skin because of insulin resistance.
Weight Loss and Fatigue
The body loses the ability to use glucose, or blood sugar, so it uses other energy sources in muscles and fat. Any excess glucose exits the body through urination, causing a decrease in calories. A person who has become diabetic will feel hungry and eat more, but will still be losing weight. Meanwhile, the cells are also losing sugar, causing the body to become tired.
Blurred Vision
High blood sugar levels may take fluid away from the eyes, resulting in blurry vision. It becomes difficult for the person to focus clearly.
Numbness
There may be tingling and numbness in the hands and feet. This may be the result of nerve disorders caused by the diabetes. Diabetics may develop nerve damage throughout the body, according to the National Diabetes Information Clearinghouse. People with these disorders may experience no symptoms, but others may experience tingling, loss of feeling or pain in the hands and feet. The legs may also be affected. There may also be intestinal problems, dizziness and weakness and urinary problems. The disorder, often referred to as diabetic neuropathy, strikes 60 to 70 percent of diabetics in some way. The risk increases with age and in people who have had diabetes for a long time.
