If after skipping a meal, you break out into a sweat, crave sweets, or feel moody or dizzy, you may be prone to hypoglycemia. If this is the case, not eating for short periods of time may significantly lower blood sugar and trigger an attack. Start eating something every couple of hours to keep your blood sugar level normal. Similarly, if you find yourself waking up in the middle of the night or first thing in the morning with a migraine, try eating a little before you go to bed. The degree of sensitivity to certain foods varies widely among people afflicted with migraine.
Some people confuse allergy with sensitivity.
An allergic reaction is when your body mistakenly reacts to a substance as though it were life threatening, and mobilizes your immune system to defend itself. Allergic reactions include symptoms like sneezing, shortness of breath, itching, skin rashes, and a constricted throat. A sensitivity on the other hand, is when your body is overly responsive to the effects of a substance. If eating a piece of cheese sets off one of your headaches, for example, it s not because you re allergic to cheese. It s probably that you re extremely sensitive to the tyramine in the cheese, which can provoke a chemical reaction in your brain.
