The weather is dry, hot and thirsty

There are many reasons for thirst. If there is something wrong with the central nervous system, you will always feel thirsty. In fact, there is no water shortage or dry mouth, but the central nervous system reacts that you are thirsty and want to drink water. There is also an immune disease called Sjogren's syndrome, which is not only thirst, but also dryness of various mucous membranes, such as dryness of eyelids and conjunctiva. Go to the hospital for examination. Don't just check diabetes, diabetes insipidus will also have abnormal thirst!

There are many diseases that will make you feel thirsty, but some people are used to carrying water with them, and if they are used to it, they are not sick. He should be very young, and his illness may not be serious. There are many here, just look at them. Pay attention to the first one. Does he have a strong taste and eat too much salt?

Reason one: the lack of water in the human body leads to thirst.

When the weather is hot, people do heavy physical labor, lose blood, burn, vomit and diarrhea, and sweat a lot due to high temperature (heatstroke), which is caused by serious water shortage in human body. In this case, people often have symptoms such as dry mouth, haggard face, eye socket collapse, dry skin and inability to stretch. Others will have symptoms of thirst because they ate too much salt that day.

Solution: Thirst caused by excessive salt intake, such as eating a salt-free diet every day, can disappear. In fact, thirst is a unique protection mechanism of human body, which can prevent human body from dehydration. Generally speaking, adults need about 2200 ml of water every day, 1000 ml of water can be obtained from food, and 1200 ml should be supplemented from drinking water to meet the physiological needs of human body. Once the water in the body is balanced, this "protective" thirst disappears.

Reason two: thirst caused by diabetes.

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 recurrent thirst. Many diabetics have high blood sugar, which will make their urine output soar. At this time, despite drinking a lot of water, I still feel thirsty.

Solution: If diabetic patients are still 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 the glucose content, while ensuring the physiological demand for water every day.

Reason 3: Brain injury leads to thirst.

Some people get thirsty after brain injury or neurosurgery. Patients can often be fatal in a day or even an hour, which is very dangerous. At this time, diabetes insipidus intensified. Patients should drink 10 liter or even 20 liters of water every day. This is because patients lack so-called "urinary hormones".

Solution: when there are patients with brain injury or neurosurgery at home, family members should take more careful care of them. Because the onset is urgent, you should see a neurologist immediately after the above symptoms appear.

Reason four: thirst caused by excessive hormones.

People with hyperthyroidism often feel thirsty. Excessive hormones often lead to tooth loss, headache, rapid fatigue, muscle weakness and sharp weight loss. Calcium lost from bones can even dye urine white.

Solution: Once the above symptoms appear, please consult an endocrinologist as soon as possible. Only by controlling hyperthyroidism and balancing metabolism can the symptoms of thirst be alleviated.

Reason five: thirst caused by kidney disease

People with kidney disease often have symptoms of thirst. This is because the kidney has lost its ability to hold water, so it needs a lot of water. There are many kinds of kidney diseases, among which pyelonephritis, glomerulonephritis and hydronephrosis all cause thirst. When urine volume decreases and edema occurs, patients will still feel thirsty.

Solution: In this case, thirst proves renal insufficiency. Unfortunately, this extremely dangerous phenomenon is often not discovered in time. Even if it is found, it is too late, so that patients can only rely on hemodialysis or kidney transplantation to continue their lives. Therefore, we should pay attention to quenching thirst in time, that is, to avoid further damage to the kidneys. Be sure to go to the kidney clinic as soon as possible for symptomatic treatment, and you can't use a lot of water to solve the thirst caused by kidney disease.

Reason six: improper medication leads to thirst.

Everyone will feel this way, and sometimes they will feel thirsty after taking medicine, which is caused by improper use of drugs, because improper use of some drugs will lead to imbalance of water and electrolytes in the body. In addition, it is thirst caused by a special drug. For example, taking antihypertensive drugs can cause dry mouth, because some antihypertensive drugs reduce the secretion of oral glands.

Solution: Some patients take the method of drinking more water, but it often can't solve the problem, and drinking more water is harmful to patients with hypertension. At this time, you should consult a doctor and change diuretics or antihypertensive drugs.
