I usually like to drink hot water, but sometimes I feel like vomiting after drinking it, and I am not thirsty at all. Why do I still feel thirsty?

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 the 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.

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.

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".

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.

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.

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.

Therefore, when you are often confused about what it is like to drink water all the time or feel thirsty, and feel that you drink a lot more water than others, and you still feel thirsty even if you feel full, then you can try drinking a glass of cold boiled water or eating a pear and mung bean soup before going to bed every day, and maybe the symptoms will be alleviated. If you still feel sick, then I suggest you go to the hospital for a check-up.
