Causes They are caused by a defect in normal bodily functions - in the case of ulcers on the legs, they are frequently the result of varicose veins, where blood is not circulating properly around the legs. Symptoms Skin ulcers can be recognised with the appearance of red, painful patches which do not heal. There may be sickness.
Internal ulcers occur more in men than women, particularly older men.
Prevention Do not smoke. Do not eat large quantities of acidic foods or very highly spiced foods. Stop smoking, if you still do. Do not drink coffee or tea, or alcohol. Comfrey tea is a good substitute.
