A common warning sign of diabetes is slow healing sores, frequent and recurring infections, especially for women. Higher levels of sugar in your urine and vagina become a breeding ground for all sorts of bacteria and yeast that causes these infections. If you suffer from recurring urinary tract infections it is cause for concern and you should definitely check for diabetes. Normal people see their sores and bruises heal in a timely manner. Diabetes causes your arteries to harden significantly. An important indicator of a healthy organism is flexible artery walls. They need to be in such a state in order to let through more blood, just in case. A good blood flow means that your wound will get coagulated fast.

High blood sugar prevents the artery walls from being flexible. It denies blood a normal passage. As your blood flow becomes more and more restricted, oxygen will be scarce in the injured areas. Oxygen-rich blood is essential to the successful healing of wounds. This may lead to more problems than you would usually face. Also, an elevated amount of blood sugar affects the red blood cells. They need free passage, as they are the carriers of nutrients. Because the artery walls will be hardened, you can face malnutrition as a consequence. Slow healing may also lead to more serious problems.
