    nyheadache posted:
    It is relatively uncommon, but over the years I have seen several patients who had a clear connection between getting constipated and getting a headache, usually of migraine type. As soon as they moved their bowels, headache subsided. It is possible that that having stool sit in the intestines longer than it should causes reabsorption of waste products which might be causing the headache. The obvious solution is to try staying regular by eating high fiber diet, good hydration, regular aerobic exercise and getting enough sleep. Magnesium supplements can not only help prevent migraines (because half of migraine sufferers are deficient in magnesium), but also prevent constipation because of their laxative effect. The usual dose is 400 mg of magnesium glycinate, citrate, or oxide.
    If constipation alternates with diarrhea, it may be worth trying gluten-free diet. If constipation occurs more often than just once a month, elimination diet can help establish if there are certain foods that may be contributing to the symptoms. Blood tests for food sensitivities can be helpful -, but most of the time elimination diet is done by fasting for a day and then introducing one or two food items at a time into your diet.
