CAUSES OF HEADACHES AND MIGRAINE
April 23rd, 2009• The causes of migraine are many. Some people are exceptionally sensitive to particular foods (typically cheese, citrus fruits, fried foods, chocolate, seafood or red wine). Others are sensitive to: stress; not enough or too much sleep; noise; certain smells; missed meals; excitement; bright and flickering lights; changes in daily routine; or the weather (especially thunderstorms and snowstorms). Migraines, and indeed all types of headache, are three times more common in women than in men. Perhaps a fall in oestrogen triggers an attack. Women taking the contraceptive pill often have headaches, and taking the Pill can make migraine worse.
• Dehydration (too little fluid) is a common cause of headaches. Most people drink too little fluid and easily become dehydrated in hot surroundings or if they miss a drink or two.
• Tension headaches are produced by anxiety and stress. They are often seen in people who are meticulous and fussy. Unlike with migraine the pain of tension headaches lasts all day. The sensation is described as being ‘like a weight pressing on the head’ or ‘a tight band around the head’. Sometimes the pain goes to the back of the head and down the neck. People who concentrate for long periods of time (such as lorry drivers) often get this kind of headache. A variation of this is the tense-jaw headache which is caused by the individual clenching the teeth.
• Hangovers are a very common cause of headaches. They are the results of consuming too much alcohol, which overloads the body’s ability to detoxify the alcohol.
• Foods cause headaches in certain susceptible people. Ice cream and very cold foods can cause pain in the head and throat. Cured meats often contain nitrates which make blood vessels around the skull wider and cause headaches. Monosodium glutamate (especially plentiful in Chinese food) causes a headache in some people-often accompanied by nausea, abdominal pains and dizziness.
• Headaches are often a sign of an impending infectious illness or fever. A simple pain-killer usually tides the person over until the cause becomes obvious.
• Head injuries are, undoubtedly, a cause of headaches but the cause is usually all too apparent and cannot readily be prevented (except for the obvious measures of driving carefully, and wearing seat-belts in cars and crash helmets on motorcycles).
• Very high blood pressure can cause a severe, pounding headache which is worse in the morning and improves during the day. The pain improves with the head up and is worse when lying down.
• Brain tumours certainly cause headaches and many people worry that they might have a tumour, especially if they have repeated headaches. However, brain tumours are very rare indeed. If your headache is worse on waking in the morning or if it is worsened by sneezing, bending down or exertion then you should see a doctor to discuss it. If you have double vision, vomiting, drowsiness or weakness in a limb and are not a migraine sufferer you should seek medical help at once.
