The answer

Night cramps are really common, especially in pregnancy and as you get older – about 1/3 of people over 60 get them. They are also more common if you have an underactive thyroid gland. Cramps can be caused by imbalance of the natural salts in your bloodstream – for instance, low sodium or low or high potassium (sometimes caused by taking water tablets for high blood pressure); low calcium or low blood sugar (if you have diabetes and take certain medicines to lower your blood sugar). Often there is no cause found for night cramps – they often run in families. However, it’s worth seeing your GP to get some simple blood tests.
