[QUOput me on low fat as there is a history of cholesterol in family and I'm due to have my gallbladder removed in few months and when I met my surgeon he said it was slightly raised"Daibell, post: 919201, member: 21149"]Hi and welcome. If you are worried you can buy a glucose meter and do some checks yourself or ask your local chemist for a spot check. Diabetes will not usually cause headaches or dizziness unless the blood sugar is very high (which, of course, it could be). The nurse was half-right when she said low-sugar and low-fat. What most of us would advise is low-carbs (sugar is just another carb) and enough fat and protein to make you feel full. Fat has nothing to do with diabetes.
