Lips are always dry. What is the specific reason?

Many factors can cause dry mouth, the most common is talking too much or drinking less water. Don't worry about this situation. This is a normal phenomenon, as long as you drink more water and pay more attention to rest. If the dry mouth is still not relieved for a week and accompanied by other symptoms, you should be vigilant. Breathe through your mouth. Your nose is blocked or you need to breathe through your mouth when swimming. When breath comes into direct contact with the oral cavity, it will dry the saliva in the oral cavity, which will lead to oral dryness. Change the bad habit of breathing through your mouth and try to breathe through your nose. Actively treat nose and mouth diseases. If there is nasal congestion, it should be treated first.

Sjogren's syndrome One of the symptoms of Sjogren's syndrome is dry mouth. In the middle of the night, I always get up and drink water because of my dry mouth, which is hard to swallow. In addition, the tongue and teeth do not have enough saliva to moisten and change the oral environment, so that the tongue surface is dry without saliva, and the cementum is damaged to varying degrees. At this stage, the teeth in the mouth are sick at the same time, accompanied by bad breath. Saliva secretion plays an important role in reducing saliva in the mouth, keeping the mouth moist, promoting food digestion and playing a role in sterilization. Under normal circumstances, when saliva secretion decreases, it will cause dry mouth. If saliva secretion decreases or tends to increase in a week, you should go to the hospital in time to see what disease is caused.

Diabetes Diabetes mellitus is a disorder of glucose metabolism, which is a typical symptom of "three more and one less", that is, drinking more, eating more, urinating more and wasting away. Because the urine volume increases, the water in the body decreases, leading to dry mouth. Because hyperthyroidism metabolism increases, heat production increases, heat dissipation accelerates, and water loss is fast, so there are bags under the eyes and goiter. Mental factors such as excessive tension, mental tension or anxiety can cause dry mouth. In addition, dry mouth can also be induced when the glands of oral mucosa shrink and saliva secretion decreases. Tip: Drink plenty of water, eat more fruits and vegetables rich in water, and improve the indoor humidity to ensure that it is around 60%-65%. Keep a positive and optimistic attitude, avoid getting too excited, and learn to adjust emotions. Proper exercise enhances physical fitness. Do not eat high-fat and high-calorie foods, and control salt intake. Keep three meals a day and avoid overeating. If the dry mouth is still not relieved, you should go to the hospital in time to find out the reason, which may be diabetes or hyperthyroidism.
