If you are always thirsty after drinking a glass of water, is a warning unhealthy sign that your body is running out of the water. This is a problem that needs attention. You are advised to see a doctor for a checkup.
Here are the reasons why you are always thirsty after drinking water as highlighted on www.prevention.com
1. Dry mouth
It's characterized by inadequate saliva in the mouth due to the failure of the saliva glands to produce enough saliva. It normally leads to nuisance symptoms such as bad breath, stringy saliva, and trouble with chewing. Dry mouth is an indication that you need medical attention. It is always accompanied by excessive thirsts.
2. Anaemia
Anaemia is characterized by less blood due to lack of iron in the body. A person with anaemia has insufficient haemoglobin in the blood. In most cases, loss of blood and pregnancy can result in anaemia. Excessive thirst is a sign that you might be suffering from anaemia. See a doctor.
3. Diabetes
Diabetes is characterized by high blood sugar level in the body due to inadequate production of insulin by the pancreas. When the level of blood sugar is high, your body will automatically subject the kidney to produce more urine as a way of getting rid of the excess sugar in the blood. This is later accompanied by excessive thirst.
