What is the cause of dry mouth

Many people may wake up from a nap and feel dry mouth in the morning; others are prone to dry mouth in dry indoor or hot weather; perhaps some feel they have dry mouth after taking medication; some even feel they somehow have dry mouth from time to time...Here is a detailed introduction to what causes dry mouth.

Dehydration in the body

Dehydration in the body is one of the causes of dry mouth. For example, if you look for people who work under high temperature, engage in physical labor, vomit, diarrhea and so on, which lead to a large amount of water loss in the body, it is easy to feel dry mouth if you do not replenish water in time. There is also a situation where too much salt intake causes dry mouth. Generally speaking, as long as the body can ensure adequate daily water intake, the body will not suffer from dry mouth due to water shortage.

Breathing through the mouth

Normal breathing is supposed to be carried out through the nasal passage. If the nasal passage is blocked for different reasons, people who are forced to breathe through their mouths are likely to have dry mouth. For example, after a person falls asleep, saliva secretion in the mouth almost completely stops, plus open mouth breathing will easily make the water in the mouth evaporate, leading to dry mouth.

Exercise

In the process of exercise, because the breathing frequency increases, the breathing depth increases, and the lung ventilation increases accordingly to meet the needs of the body, so that the water can be taken away greatly in breathing, resulting in dry mouth. In addition, when exercising the body because of the large amount of sweat secretion will also cause the body to appear blood concentration affect saliva secretion, resulting in dry mouth.

Drug side effects

People who often take drugs orally are prone to dry mouth due to the reduction of oral saliva secretion caused by drugs. According to incomplete statistics, there are at least 250 kinds of drugs that can inhibit the secretion of saliva to different degrees. The dry mouth that occurs after taking medication can usually be restored to normal saliva production after stopping the medication.

Radiation therapy

Patients with malignant tumors of the head and neck who undergo radiation therapy are prone to have their salivary glands destroyed, reducing or even stopping salivary secretion. Such patients not only need to eat a soup-oriented diet but also need to inhale water to moisten their mouth before speaking to communicate normally.

Menopause Symptoms

Dry mouth is a symptom of menopause. During menopause, the body is prone to many discomforts, and women in particular are prone to menopause syndrome. Dry mouth and irritability are very common subjective feelings during menopause.

Slow metabolism

For the elderly, if the body's metabolism slows down and the body's functions begin to decline, it is easy to see that the salivary gland secretion function also decreases, the nervous system response decreases, etc. At this time, the oral mucosa is easy to lose its elasticity due to dryness, thus appearing dry mouth.

Dryness syndrome

If there is a problem with autoimmunity, people suffering from dry syndrome may suffer from the destruction of the exocrine glands in various parts of the body because of the disease. The salivary glands and lacrimal glands are the first to suffer, so it is easy to have dry mouth, dry eyes and other discomforts. Those who are often unwell can consider medical examination.
