Everyone will feel this way. Sometimes, after taking medicine, they will feel dry and dry. This is thirst caused by improper medication, because improper use of some drugs can cause imbalance between water and electrolytes. In addition, it is thirst caused by a special medicine. Such as: taking antihypertensive drugs will cause dry mouth, which is because some antihypertensive drugs reduce the secretion of oral glands.

2, thirst caused by diabetes

One of the functions of hormones is to coordinate the metabolism of water and salt in the human body. Once the balance of this hormone is destroyed, it can cause frequent thirst. Many people with diabetes have high blood sugar and their urine output will increase dramatically. At this time, despite the large amount of drinking water, you will still feel thirsty.

3, thirst caused by brain damage

Some people are also thirsty after brain injury or neurosurgery. Patients are often fatal and dangerous in one day or even an hour. At this time, diabetes insipidus is intensified. Patients drink 10 liters a day or even 20 liters of water a day. This is because the patient lacks the so-called "restricted urinary hormone".

4, thirst caused by excessive hormones

People with hyperthyroidism often feel thirsty, and excess hormones often cause the patient's teeth to fall off, suffer from bone pain, rapid fatigue, muscle weakness, and rapid weight loss. Calcium lost from the bone can even stain the urine white.

5, thirst caused by kidney disease

People with kidney disease often have symptoms of thirst. This is because the kidney has lost the ability to retain moisture and therefore requires a large amount of water. There are many kinds of kidney diseases, including pyelonephritis, glomerulonephritis, hydronephrosis, etc., which can cause thirst. The patient still feels thirsty when the amount of urine is reduced and edema is present.
