At three years out from surgery, I found myself getting into trouble with symptoms of low blood sugar.  

If you experience hypoglycemia there are certain dietary changes that will help you feel more in control and normalize your insulin levels. I have found it necessary to make sure I eat enough protein along with getting the right amount of carbohydrates, fat and fiber.

Eating the right kind of carbohydrates is extremely important—learning to replace refined carbs with complex carbs will be necessary. Learning all you can about foods and nutrition will be very helpful.

Hypoglycemia is not uncommon in weight loss surgery patients, even (or should I say especially) years later, you must find what works for you. Working with a dietitian is very helpful in solving this issue. 

I have been doing some research on hypoglycemia and gastric bypass, if you still cannot control your low sugar drops with diet, you may need to see your dietitian and then your surgeon for further help in this area. Although dietary changes can correct the problem, on rare occasions it might be necessary to consult a doctor. (weight loss surgeon, endocrinologist, or someone who is familiar with hypoglycemia after weight loss surgery)

Dieticians could be covered by your insurance but regardless whether insurance helps or out of pocket, finding a good dietician is vital to your health and weight loss success. New information is coming available continually and we need to stay informed.
