16 Signs of Hyperglycemia

2. Headaches

A person with diabetes may suffer from debilitating headaches. This is adding insult to injury it seems like, because with having to keep your blood sugar in check, and all of the various bodily functions that aren’t working properly because of too much glucose, a headache is the last thing you need.

The reason that it happens is that your blood sugar level drops or rises too quickly, which can cause anything from a mildly irritating headache to a full-blown migraine that makes you unable to even get out of bed.
