I've had Migraines on and off since puberty. I can usually attribute mine to my monthly cycle or dehydration. Post op I've had some days that it was difficult to get all of my required Water in and it usually results in a Migraine the next morning. Not getting proper Protein can also do this now. When you initially change your diet it's possible that you'll experience headaches or migraines because it's a change to your normal intake. I changed my diet drastically with the guidance of my NUT about 6 weeks before surgery which I think helped the transition to the post op diet.
