I often feel thirsty, and it's no use drinking more water. What disease could this be caused by?

Today, let's talk about what causes dry mouth. Many of us have had this experience: if we eat salty food, we will obviously feel sore throat and want to drink water constantly. This is actually because our body has a strong balance system, people eat too much salt, and the kidneys need to consume a lot of water to discharge excess salt, so people will feel particularly thirsty.

If you are thirsty, drinking water will not help. You may have diabetes. The early precursor of diabetes is often dry mouth, and drinking water will not help, and the number of urination will increase. This is caused by high blood sugar, and the body tries to protect itself by drinking plenty of water, increasing urine and discharging excess sugar.

If you are thirsty, drinking water will not help, which may be hyperthyroidism. Hyperthyroidism patients sweat more and have a fast metabolism, which leads to a lot of drinking water. This is why they are often thirsty and think drinking water is useless.

If you feel thirsty, drinking water is no good. Be careful that you are anaemic. Usually, anemia patients lose red blood cells faster than they produce red blood cells, lose water faster, look pale and have symptoms of dry mouth.

If your mouth is thirsty and drinking water won't help, then you may have eaten too much salt. Salt contains a lot of sodium, which will affect the water balance system after entering the human body, resulting in the reduction of water in the blood. In addition, the kidneys will lose some water in the process of excreting sodium, and the body will become dehydrated. Only by constantly replenishing water can we replenish water.

If your mouth is dry and drinking water doesn't help, beware of Sjogren's syndrome. This is an abnormal dryness of oral mucosa, which can be caused by a decrease in saliva volume or a change in saliva composition. But this disease is extremely rare and should be examined by a doctor.

In addition, for the aging of thirst, some surveys have found that about 30-50% of all the elderly people will have dry mouth to varying degrees. When people reach a certain age, the organs of the body begin to decline, the oral environment is also changing, and saliva begins to decrease. The original water content in saliva is above 99%. If saliva secretion is too little, it will naturally make people feel thirsty.
