I still feel thirsty even though I drink a lot of water

The human body needs to consume a large amount of water every day to ensure the normal functioning of the body. In addition, the human body will have many symptoms when it is dehydrated, among which thirst is the most direct symptom. When thirst occurs, it is the body's way of reminding people that they need to replenish a lot of water, so they need to drink water in time. But sometimes thirst is not just caused by lack of water. Many people find that they are still thirsty after drinking a lot of water. Why?

Reason 1: Lack of water in the human body causes thirst

People will feel thirsty when the weather is hot, when doing heavy physical labor, when losing blood, when suffering from burns, when vomiting, when having diarrhea, or when sweating profusely due to high temperature (heat stroke). This is because the thirst is caused by severe lack of water in the human body.

In this case, the human body will experience symptoms such as dry mouth, haggard face, sunken eye sockets, and dry and inflexible skin. Some people may experience thirst symptoms because they eat too much salt that day.

Reason 2: Diabetes causes thirst

Hormones in the human body can coordinate the metabolism of water and salt in the body. Once the balance of this hormone is disrupted, it will cause frequent thirst. Diabetes is caused by a disorder of the body's hormone levels, which leads to an increase in the body's blood sugar content, so there will be thirst. Even if you keep drinking water, you will still feel thirsty.

When this happens, you should take hypoglycemic drugs as soon as possible to control the condition and avoid thirst. If the thirst symptoms worsen while taking the medication, it is likely that the condition has worsened and you need to go to the hospital for examination as soon as possible.

Reason 3: Thirst caused by kidney disease

People with kidney disease often experience symptoms of frequent thirst. This is because the kidneys have lost the ability to retain water, so they drink a lot of water, but still feel thirsty. In addition, when the body's urination decreases or edema occurs, the body will also experience symptoms of thirst. There are many types of kidney disease, among which pyelonephritis, glomerulonephritis, hydronephrosis, etc. can cause thirst. If the thirst is caused by kidney disease, you need to go to the hospital for treatment in time to avoid worsening of the condition.

Reason 4: Drug abuse causes thirst

Some people need to take medication for a long time to control their condition. If they take too much or improperly, it will cause this frequent thirst. This is because drug abuse will affect the human central nervous system or cause an imbalance in the body's water and electrolytes, thereby causing symptoms of frequent thirst. In addition, taking certain special medications can also cause thirst. For example, taking antihypertensive drugs can cause dry mouth. This is because some antihypertensive drugs reduce the secretion of oral glands.

Note: When taking medication, be sure to follow the doctor's instructions or instructions, and never change the type or dosage of medication at will.

Reason 5: Hyperthyroidism causes thirst

People with hyperthyroidism also often feel thirsty. This is because the thyroid gland synthesizes and releases too much thyroid hormone. Thyroid hormone promotes metabolism and the body's redox reaction. Hypermetabolism requires the body to increase food intake and replenish more water, so frequent thirst will occur.

Hyperthyroidism can cause hypermetabolism and sympathetic nerve excitement, leading to symptoms such as palpitations, sweating, increased eating and bowel movements, and weight loss. Most patients also often have symptoms such as exophthalmos, eyelid edema, and decreased vision. At this time, patients need to go to the hospital for treatment in time to avoid worsening of the condition.
