Dr. He Haochen
Dry mouth and constant thirst may be caused by various factors, mainly as follows:
1. Environmental factors: Prolonged exposure to high temperatures or dry environments can lead to dehydration, resulting in dry mouth and thirst.
2. Insufficient water intake: Drinking too little water or having poor hydration habits, such as failing to replenish fluids in a timely manner, can also cause dry mouth and thirst.
3. Medical conditions: Diseases such as diabetes, Sjögren's syndrome, and hyperthyroidism may cause abnormalities in the body's water and salt metabolism or reduce saliva production, leading to dry mouth and thirst.
4. Medication factors: Certain medications, such as antihypertensive drugs and anticholinergic drugs, may reduce saliva production in the mouth, causing dry mouth and thirst.
In response to these causes, it is recommended to maintain good hydration habits, avoid prolonged exposure to hot or dry environments, seek timely medical examination and treatment for related conditions, and adjust medication use under a doctor's guidance.
