| I can get a Headache when my BG levels changes a lot over short period of time. So I suggest you test our BG 30 min and 1 hour after meal, sometimes, just to check what is going on. After two hours BG should in most cases be back to normal. But if BG is either to high or to low after one hour, this can be the cause of your headache. In that case you probably have to adjust your diet. I might also be that you are slightly allergic to some of the food you eat. |
