Mouth ulcers, commonly known as mouth sores, are a common disease of the oral mucosa, and people will inevitably be plagued by mouth sores throughout their lives. In the people’s understanding, mouth ulcers seem to be not a big problem, just “on fire” or “eat less vegetables, vitamin deficiency”, is it really so? Here to look at the misconceptions of mouth ulcers: Myth 1: mouth ulcers are not afraid, is a “minor problem” If it is an occasional mouth ulcer, it does not seem to be a big problem; if the mouth ulcer recurring, or accompanied by other symptoms, it should cause us enough alarm. Because many systemic diseases can be manifested as local oral mucosal ulcers, such as systemic lupus erythematosus, leukodystrophy and other rheumatic diseases often appear recurrent oral ulcers, then the oral ulcers at this time is not a minor problem. Even if it is simply “recurrent mouth ulcers”, ulcers repeatedly do not heal, pain, bring eating and drinking, open mouth to speak difficulties, but also seriously interfere with our quality of life. At the same time, some mouth ulcers that do not heal can gradually develop into oral cancer. Myth 2: Mouth ulcers mean “vitamin deficiency” When mouth ulcers occur, many people think it is vitamin deficiency, and general doctors will give patients vitamin B2 and multivitamin to treat them. In fact, vitamin deficiency is only seen in some patients with mouth ulcers, such as poor eating status, after intestinal surgery, stomach ulcers, atrophic gastritis and other patients. Most patients with mouth ulcers will not be deficient in vitamins as long as they eat well. It is important to know that the occurrence of mouth ulcers is related to the immune status of the body, mental and psychological stress, genetic factors, local microcirculation, endocrine, fatigue and many other factors, not just vitamin deficiency. Myth 3: Mouth ulcers are “fire” Mouth ulcers are “fire”, the people will be issued mouth ulcers will boil some Huang Lian water to drink or eat some Huang Lian Shangqing pill, will have a certain effect. This understanding also has some truth, Chinese medicine believes that the fire (heart and stomach fire) on the attack on the mouth and tongue can appear mouth and tongue ulcers, sore throat and other symptoms. But in fact, mouth ulcers are not all due to “fire”, Yin deficiency (false fire), damp heat, Yang deficiency, liver depression and many other factors can lead to mouth ulcers, should be treated dialectically, do not see mouth ulcers on the heat detoxification and fire treatment. In short, for the mouth ulcer, we should pay enough attention, should emphasize that the mouth ulcer treatment at the same time, but also to do a good life regimen: 1, pay attention to oral hygiene; 2, quit smoking and alcohol, less spicy and irritating food; 3, drink more water, often eat fruits and vegetables; 4, do not stay up late, sleep enough; 5, do not overwork, life in moderation; 6, less fire, keep a happy mood; 7, keep the stool flowing 8.
