Why do you feel thirsty?

1.1 Dehydration Dehydration is a condition in which the body does not have enough water to serve its normal functions. It is caused by many causes such as exercise, diarrhea, vomiting, and excessive sweating. In addition to thirst, signs of dehydration may include:
Dark urine No need to urinate often Dry mouth Dry skin Feeling tired or lightheaded Headache

In addition, children who are dehydrated may also show symptoms such as:
Few or no tears when crying Dry mouth Urinating less or less wet diapers Irritability or sluggishness 1.2 Diabetes Diabetes causes the body to increase water consumption, leading to dehydration, which makes you feel thirsty throughout the day. This is because glucose builds up in the body, it absorbs more water, causing you to urinate more. From there, the body responds by stimulating the feeling of thirst.
Along with increased thirst and urination, other symptoms of diabetes include:
Blurred vision Feeling very tired Increased feeling of hunger Slow-healing cuts and bruises 1.3 Diabetes insipidus Common diabetes insipidus unrelated to diabetes. It occurs when the body doesn't make enough hormones that help the kidneys control the amount of water in the body. Extreme thirst is one of the main symptoms of the disease. In addition, some other symptoms appear such as:
Dehydration Frequent urination

1.4 Dry mouth Dry mouth is often a sign of thirst. It occurs mainly because the salivary glands make less saliva. Dry mouth can be caused by taking medications, treating other conditions such as cancer, Sjogren's syndrome, nerve damage to the head and neck, and smoking.
If the salivary glands do not produce enough saliva, some symptoms other than dry mouth may also occur such as:
Bad breath Change in taste Irritated gums Irritated gums Lipstick sticks to teeth Thick saliva Difficult to chew 1.5 Anemia Anemia is a condition in which the body does not have enough healthy red blood cells in the body. The disease can be congenital or acquired. Anemia is caused by many causes, which include illness, poor diet or severe bleeding.
Mild anemia does not usually cause thirst, but severe anemia is different. In addition to thirst, the body also shows:
Dizziness Feeling tired and weak Pale or yellowish skin Fast pulse Sweating

The degree to which water is replenished depends on the cause of thirst. The best way to cure thirst is to drink more water.
