Oral diseases: such as malocclusion of upper and lower teeth, deviation of nasal septum, lower turbinate hypertrophy, nasal polyps, etc. These people often open their mouths to breathe, and the gas in their mouths breathes in and out, taking away more water and causing dry mouth.
Chronic lung diseases: emphysema, chronic bronchitis, etc. Especially for some elderly people, their lung function is generally poor, their bodies are seriously deprived of oxygen, and they often take compensatory breathing with their mouths open. Once the lung function is improved, the symptoms of dry mouth can be alleviated. ?
Vitamin B2 deficiency: When the body lacks vitamin B2, it will also cause dry mouth, oral ulcer, dry throat and tongue ulcer.
Three methods to prevent and treat dry mouth and xerostomia

2. Eat medlar at night to treat oral symptoms: eat 30 grams of medlar every night. The more you chew, the worse it is. Stick to it. However, it should be pointed out that for the elderly with long-term dry mouth, further examination should be carried out. For example, some people have cancer, but also mouth-to-mouth phenomenon. Please don't be careless. In addition, for diabetics or the elderly who feel thirsty due to decreased secretion of body fluids, especially at night, Lycium barbarum can be washed for later use. If necessary, you can put a piece on your tongue. After a few seconds, the tongue root will produce body fluid to relieve thirst. You don't need to drink water all night before you go to sleep.

Honey and rice vinegar for dry throat and sore tongue: once a day in the morning and evening, each time 1 spoonful of honey is added with 2 spoonfuls of rice vinegar and a large cup of boiling water, which will improve after drinking for several months, and abnormal stools can also return to normal.
