Symptoms of Diabetes

Blurry Vision and/or Dry, Itchy Skin
Blurry vision is also a common symptom of diabetes. This is because a high amount of sugar in the blood actually pulls fluid out of your tissues, including the lenses of your eyes. This decrease in fluid affects your ability to focus properly. In other parts of your body, the decrease in fluid can also lead to dry, itchy skin.
 
Tingling Sensations
Over time, high levels of sugar in the blood can damage the small blood vessels that supply the nerves. This can lead to problems such as tingling, pain, or numbness in the hands or feet.
 
Sores That Don't Heal
Diabetes affects the body's ability to heal and fight infection. So if you have diabetes, it may take longer for a sore to heal.
 

Comparing Symptoms of Diabetes

Type 1 diabetes and type 2 diabetes are the two most common types of this condition (see Diabetes Types). There are a couple of things to keep in mind when comparing type 1 and type 2 diabetes symptoms. Type 1 diabetes usually begins before the age of 40, with most people developing it as teenagers. Symptoms usually develop more quickly, and, in some cases, the first symptom of type 1 diabetes can be a life-threatening coma, known as diabetic ketoacidosis, or DKA.

 
Often, children will be vomiting, a sign of DKA, and will be mistakenly diagnosed as having gastroenteritis (more commonly known as the stomach flu). However, new-onset diabetes is different from a GI infection, because frequent urination often accompanies continued vomiting, whereas if the vomiting is caused by a GI "bug," there is a decrease in urination, due to dehydration.
 
Type 2 diabetes is a condition that usually begins during middle age or beyond. The symptoms of type 2 diabetes usually develop gradually and are not as noticeable as in type 1 diabetes. In fact, it is not uncommon for people to have no symptoms of type 2 diabetes in the beginning, prior to being diagnosed; instead, they are diagnosed with diabetes after a routine laboratory test.
