Cause 1: Thirst caused by water shortage in human body When the weather is hot, doing heavy physical labor, blood loss, burns, vomiting, diarrhea, sweating a lot due to high temperature (heat stroke), people will feel thirsty, which is caused by serious water shortage in human body. In this condition, people often experience symptoms such as dry mouth, haggard face, collapsed eye sockets, and dry and unstretchable skin. Others will suffer from thirst symptoms due to too much salt eaten that day. Solution: Thirst caused by excessive salt intake can disappear if you can eat a salt-free diet every day. In fact, thirst is a unique protective mechanism of the body itself, which can save the body from dehydration. Generally speaking, adults need about 2,200 ml of water per day, 1,000 ml of water from food, and the other 1,200 ml should be supplemented by drinking water to meet the body’s physiological needs. Once the body’s water balance is restored, this “protective” thirst will disappear. One of the roles of hormones is to coordinate the metabolism of water and salt in the body. Once the balance of this hormone is disrupted, it can cause frequent thirst. Many diabetics have high blood sugar, which causes their urine output to skyrocket. At this point, despite drinking plenty of water, the thirst can still be unbearable. Solution: If a person with diabetes continues to feel thirsty while taking insulin or glucose-lowering medication, this is an indication that his or her condition is worsening. In this case, you should go to the hospital to check your blood sugar and start taking glucose-lowering medication immediately, and at the same time, you should ensure your daily physiological requirement of water. Cause 3: Thirst caused by brain injury Some people also experience thirst after brain injury or neurosurgery. Patients can often be dangerously fatal within a day, or even an hour. This is when the thirst is exacerbated. Patients have to drink 10 liters, or even 20 liters of water a day. This is due to the lack of so-called “urinary restriction hormone” in the patient’s body. Solution: When there is a patient with brain injury or after neurosurgery in the family, the family should take care of him/her more carefully. Because of the urgency of the onset, you should see a neurologist immediately after the onset of these symptoms. Cause 4: Thirst caused by excess hormones People with hyperthyroidism often feel thirsty, and excess hormones often lead to tooth loss, bone pain, rapid fatigue, muscle weakness, rapid weight loss, and loss of calcium from bones that can even turn the urine white. Solution: Once the above symptoms appear, an endocrinologist should be consulted as soon as possible. Control hyperthyroidism and balance metabolism in order to relieve thirst symptoms. Cause 5: Thirst caused by kidney disease People with kidney disease also experience frequent symptoms of thirst. This is because the kidneys have lost their ability to retain water and therefore need a lot of water. There are various kidney diseases, among which pyelonephritis, vascular bulb nephritis and hydronephrosis can cause thirst. Patients may still feel thirsty when urination is reduced and swelling occurs. Solution: The thirst that occurs in this condition proves that their kidneys are not functioning adequately. Unfortunately, this extremely dangerous phenomenon is often not detected in time. Even if it is detected, it is already too late, so that the patient has to resort to hemodialysis, or kidney transplantation to extend his life. Therefore, timely attention to thirst means to save the kidney from further damage. Be sure to go to the nephrology clinic early for symptomatic treatment, and not use a lot of water to solve the thirst caused by kidney disease. Cause 6: Thirst caused by improper use of medication Everyone will have the feeling that sometimes after taking medication, you will feel dry mouth, which is thirst caused by improper use of medication, because some medications can lead to imbalance of water and electrolytes in the body when used improperly. In addition, it is the thirst caused by a particular drug. For example, taking antihypertensive drugs can cause dry mouth, which is because some antihypertensive drugs reduce the secretion of oral glands. Solution: Some patients take a lot of water, but often can not solve the problem, and a lot of water is also harmful to patients with high blood pressure. In this case, the doctor should be consulted, while replacing diuretics or antihypertensive drugs. Cause 7: Unexplained thirst There are also some unexplained thirst phenomena, which is a very annoying disease that makes doctors and patients scratch their heads. Most of the patients who suffer from these unexplained thirsts are women. In addition to the unexplained thirst, they are also capricious, irritable and aggressive. Solution: This is often a neuropsychiatric thirst. In such cases, patients may wish to cheat their bodies, such as holding up a glass of water and making several swallowing motions in succession. You can also moisten your lips with water, which can sometimes produce the pleasure of quenching thirst.
