What should I do if I have frequent mouth ulcers? I have been suffering from diabetes for 13 years. I do not know why recently always love oral fire, and always have mouth ulcers, always recurring, I would like to ask what is the reason for this, and diabetes is not related, how to care for my mouth in daily life, to ensure oral health? For those who have frequent mouth ulcers, pay special attention to dietary hygiene and establish good dietary habits 1. To reduce the stimulation of ulcers, so try to eat less irritating condiments, such as chili peppers, sour vinegar, ginger, green onions, star anise, curry, etc. 2, to reduce the friction of the ulcer, so to eat less fried food, such as fried pork chops, fried chicken legs, and other too rough and hard food. 3, to pay attention to nutrition, balanced diet, in addition to adhere to the daily consumption of fish, meat and other meat dishes, but also must eat more fresh vegetables and fruits to supplement a variety of nutrients. 4, to eat more easily digestible food, such as soy products, eggs and so on, in the ulcer attack period, but also pay attention to less meals, into the semi-liquid, in order to facilitate eating, do not be afraid of pain and eat less or even do not eat. 5, each time after eating, to develop a good habit of immediate mouth rinsing, available salt water, saline, but also available drug mouthwash, to prevent secondary infection due to food residue aggravation. 6, certain “hairy things” that can easily cause the onset of mouth ulcers to avoid, common “hairy things” including a variety of bamboo shoots (asparagus, bamboo shoots, bamboo shoots, dried bamboo shoots), pickled products (salted fish, salted meat, pickles), persimmons, crabs and so on. But not everyone is sensitive to every “hairy” thing, so patients should also find their own “hairy” things from their own personal recipes to avoid.
