What is the reason for frequent thirst? So is drinking water.

First, the human body is seriously short of water:

Hot weather, heavy physical labor, blood loss, burns, vomiting, diarrhea, sweating at high temperature, etc. Can lead to serious water shortage and thirst, and then often appear the following symptoms, namely: dry mouth, haggard face, eye socket collapse, dry skin, inability to stretch. In fact, thirst is a unique protection mechanism of human body, which can prevent human body from dehydration. When thirsty, the human body naturally needs to replenish a lot of water. Once the water in the body is balanced, this "protective" thirst disappears.

Secondly, diabetes is the culprit:

One of the functions of hormones is to coordinate water and salt metabolism in human body. Once the balance of this hormone is broken, it will cause frequent thirst. Diabetic patients with high blood sugar will make the urine output soar. Although I drank a lot of water at this time, I still felt thirsty. If diabetics still feel thirsty while taking insulin or hypoglycemic drugs, it means that their condition is getting worse. In this case, you should go to the hospital to check your blood sugar, and immediately start taking drugs to reduce your glucose content.

Third, brain injury:

Some people get thirsty after brain injury or neurosurgery. Its characteristics are: the onset is urgent, and patients can often die within one day or even one hour. At this time, diabetes insipidus intensified. Patients should drink 10 liter or even 20 liters of water every day. It turns out that this is entirely due to the lack of so-called "urinary hormones" in patients. Because the onset is urgent, you should see a neurologist at once.

Fourth, hormone excess:

The first symptom of hyperthyroidism is also thirst. Excessive hormones lead to tooth loss, headache, rapid fatigue, muscle weakness and sharp weight loss. Calcium lost from bones can even dye urine white. Please consult an endocrinologist as soon as possible.

Five, kidney disease:

The kidney has lost its ability to hold water, and as a result, it needs a lot of water. There are many kinds of kidney diseases, among which pyelonephritis, glomerulonephritis and hydronephrosis all cause thirst. Its characteristic is that even if the amount of urination is reduced and edema appears, the patient still feels thirsty. Thirst in this case proves renal insufficiency. Unfortunately, this extremely dangerous phenomenon is often not discovered in time. By the time it was discovered, it was too late, so that patients could only continue their lives with hemodialysis or kidney transplantation. Therefore, we should pay attention to quenching thirst in time, that is, to avoid further damage to the kidneys. At this time, it is very important to ask a nephrologist for treatment.

Six, improper medication:

Improper medication often causes thirst. For example, some antihypertensive drugs often cause dry mouth. Therefore, patients need to drink more water. Drinking plenty of water is harmful to patients with hypertension. At this time, you should consult a cardiologist and change diuretics.

Seven, unexplained thirst:

This is a very annoying disease. Most people suffering from this disease are women. Its characteristics are: patients often feel thirsty for no reason, but also show arbitrariness, anger and aggression. In this case, the patient may wish to cheat his body, such as lifting the water cup and doing several swallowing actions in succession. Or scoop a cup of salty sea water and pretend to drink it on purpose. If water is clean, it can also be used to moisten lips. These "tricks" are enough to deceive the patient's brain, and he can feel a kind of thirst-quenching pleasure for a period of time.
