I often get dizzy before during and sometimes after a meal is this a blood sugar issue? every time i have it checked comes back normal help!

Are you overweight?: If you're overweight (and particularly if you have a family history of diabetes) you may be progressing down the road to type 2 diabetes and have high glucoses with a meal and then a rapid correction - which can cause symptoms, but not true hypoglycemia. If you are overweight, get on a life-long diet, exercise and weight loss program or prevent or delay diabetes.
