"Doctor, I seem to be suffering from a strange disease!" Uncle Sun found the doctor in a hurry, describing his condition.

Over 50 years of age, Sun's uncle recently had a period of abnormal body, often feels dry mouth, especially at night dry mouth, sometimes in the middle of the night also has to get up to drink water, but less urine constipation during the day, all the symptoms make him suffer.

"Hey, every day, sore throat, mouth stink, family members are avoiding me." Uncle Sun sighed with a slow breath, "Doctor, look at my mouth, dry and cracked and bleeding, tormenting me to the point of demons."

Finally, the doctor diagnosed that the "culprit" of Uncle Sun's strange disease was dryness syndrome.

Many people may have experienced symptoms similar to Sun Da-bo. What is the problem of dry mouth when sleeping at night? Is it related to the disease?

A. What's wrong with having a dry mouth at night?

In life, people always encounter dry mouth and very want to drink water, but when this situation rarely appears at night when sleeping at night with a dry mouth is not uncommon.

Generally speaking, a dry mouth means that the body is dehydrated. When the body is in a state of dehydration, dehydration, water, and salt metabolism in the body will stimulate the body to send out "hydration signals", and this signal is expressed in the symptoms of thirst and dry mouth.

There are five main physiological causes of human dehydration.

First, insufficient daytime hydration. The human body in daytime activities, not timely replenishment of water, may also in night activities, or sports because of urine, and sweat lose a lot of water, resulting in a bedtime will be or has entered a state of dehydration.

Second, the sleep environment is dry. The human body's sleep environment air humidity is seriously insufficient, which will lead to rapid water loss in the body, it is possible to wake up before waking up due to dehydration.

Third, open-mouth breathing during sleep. Some people sleep with their mouths open to breathe, which will lead to increased water loss pathways and faster loss, and because the mouth is open, it is more likely to cause the phenomenon of dry mouth.

Fourth, too much salt intake. Excessive salt intake will lead to an increase in plasma osmolarity, which will stimulate the thirst center and osmolarity receptors in the hypothalamus, thus triggering the feeling of thirst.

Fifth, the body function degeneration. After the degeneration of the glands that secrete saliva in the elderly, the mouth is more prone to dryness, and if the problem of hydration is neglected, dry mouth often occurs at night.

In the above cases, as long as the timely replenishment of water, thirst symptoms will be relieved, but it is recommended to replenish water in small amounts several times, do not drink a lot of water at once. At the same time after drinking water for some time thirst symptoms can not be relieved, and we must seek medical examination as soon as possible.

Second, dry mouth and drinking water are difficult to relieve, be alert or 6 kinds of disease signal

The vast majority of thirst conditions, as long as the water will be reduced, but sometimes disease caused by thirst, even if drinking water will not help, or only solve a moment, be alert to 6 types of pathological factors.

1、Digestive and respiratory system diseases

When the digestive system occurs oral inflammation, stones, such as mumps, submandibular gland inflammation, and oral gland stones, respiratory system occurs when the cold, fever, runny nose, and other diseases, the human body will also be insufficient saliva production, inflammation, hyperthermia, water loss, and dehydration symptoms.

In addition, chronic bronchitis, chronic obstructive pulmonary disease, and other diseases that may cause obstructed and poor breathing may also cause patients to open their mouths to breathe, thus causing dry mouth.

2、Thyroid disease

When the human body has hyperthyroidism, it will cause the parathyroid glands (both sides of the neck) to be in a state of overexcitation, when the blood calcium level in the human body increases and the blood phosphorus level decreases, it may cause thirst, polyuria and other psychoneurological symptoms.

Patients may also experience symptoms such as a thick neck, rapid heartbeat, irritability, sweaty hands, fatigue and weakness, and generalized aches and pains. In addition, a few patients may also have the risk of osteoporosis, bone and joint pain, renal colic, etc.

3、Dry syndrome

When the human body changes to autoimmune diseases such as dry syndrome, the glands that secrete saliva may be damaged by immune cells, resulting in a dry mouth. Patients are often accompanied by dry hands, dry eyes, dry skin, and other symptoms, and need to drink water frequently to replenish, and in severe cases, teeth and tongue may become sticky, and need to drink water all the time.

In addition, the clinical investigation found that two-thirds of dry syndrome patients will also have impaired kidney function, interstitial lung lesions, lymphatic system dysfunction, and other conditions, and face the risk of systemic damage.

4、Diabetes

In diabetic patients with high blood sugar levels, the kidneys have to increase the burden to solve the excess glucose and keep "working" to produce urine, and at the same time, it will lead to renal tubular disorder, and the increase of glucose in urine will trigger the hyperosmolarity, so there will be symptoms such as excessive drinking and urination, thirst and dry mouth. It may also be accompanied by emotional irritability and weight loss.

5、Liver and gallbladder disease

The liver is the metabolic organ and detoxification organ in the body. When the liver is diseased, the liver is unable to assist the gallbladder, which can also lead to impaired gallbladder function. When the bile refluxes into the esophagus and throat, it will cause symptoms such as the dry mouth and bitter mouth. Patients with liver and gallbladder disease may also develop jaundice, liver palms, spider nevus, and other symptoms.

6、Urinary collapse

Analysis, which refers to the lack of antidiuretic hormone in the body or kidney insensitivity to antidiuretic hormone and causes renal tubular dysfunction, gives the illusion of water shortage in the body and signals thirst. Dry mouth in patients with uremia is accompanied by an increase in nocturnal urination, and the total amount of urination in a day can reach more than 4-10 liters.

Third, dry mouth, so drink water to work, remember the 4 details

Dry mouth everyone will encounter, this time it seems to drink water can be resolved, but hydration is also a skill, master not haphazardly drinking water also easy to hurts the body.

1, replenish enough water

An adult's normal daily needs to replenish 1500-1700 ml of water, plus the hot environment, activities, water loss, etc., the right amount of water is also necessary to increase. Therefore, we should grasp the amount of water, a small number of times to supplement.

2, do not wait until thirsty hydration

When thirsty, the body is often already in a state of dehydration, when the body's nerves, organs, and tissue dehydration may cause damage, so be sure to replenish water before thirst.

3, don't use carbonated, sweet drinks for hydration

Carbonated, sweet drinks will make the body lose more water, it seems to drink more, and the actual effect is not good.

4, quench thirst preferably 4 types of "water"

The best water to quench thirst is pure water, light tea (green tea, black tea, white tea), sliced fruit bubble water, soup water (barley, buckwheat bubble water, green bean soup), and so on.

Fourth, how to prevent dry mouth and thirst?

When the human body has dry mouth symptoms, it is important to first investigate the pathological factors, only the right treatment, to solve the root cause, can be once and for all. However, it is still necessary to do a good job of prevention daily, and do 3 things to try to avoid dry mouth.

First, do a good job of oral hygiene daily to avoid oral and respiratory diseases. Second, regular work and rest, avoid staying up late, three regular meals, and try to avoid tobacco, alcohol, spicy, and other stimulating food.

Third, an optimistic state of mind, away from bad emotions, to avoid anxiety and fire. Fourth, regular oral examination, twice a year is best, and timely discharge of health risks.

Finally, improve the environment before going to bed, if dry you can turn on the humidifier to increase air humidity. If it is a climatic factor, you can eat more snow pear, ginseng fruit, honey water, and other lung-moistening and nourishing foods to relieve and prevent dry mouth.

Dry mouth may seem insignificant, but episodes can have some impact on life and it can also be a sign of disease. Therefore, it is recommended that you must pay attention to dry mouth symptoms, especially dry mouth at night, accompanied by all kinds of abnormal symptoms, it is best to seek a medical examination.
