4. Slow Healing
One of the downsides of diabetes is that you don’t heal as quickly as you should. Cuts and scrapes that used to heal up in a day or two may take a week or longer when you have diabetes. Unfortunately, when this happens people do not always see it as a symptom of diabetes.
Instead, they attribute it to getting older or some other cause. This is why their diabetes does not get diagnosed until later. But if you are aware of this silent symptom, then you will be able to get checked out by your doctor and find out what your blood sugar levels are.
