The reason why the tongue always ulcerates may be that the body lacks enough trace elements, endocrine changes, genetic factors, etc. If the body lacks iron, zinc, folic acid, vitamins or trace elements, the immune function will be reduced, thus increasing the possibility of tongue ulcer attacks. When menstruation comes, women's tongues are prone to ulceration, because during menstruation, progesterone in the body will increase, while estrogen will decrease, leading to tongue ulceration, which may also be accompanied by irritability, upset, and dry mouth. If both parents or one of them often has symptoms of tongue ulcers, their children are also more likely to have tongue ulcers than others. The reason why the tongue is always ulcerated is also due to mental factors and irregular work and rest. We should pay attention to staying up less, working and resting regularly, quitting smoking, drinking more water, and ensuring oral hygiene can accelerate the healing of tongue ulcers.
