Why is my mouth dry and I feel thirsty?

Dry mouth can have various causes. It may result from dehydration, especially in dry environments or when fluids are not replenished for extended periods. Poor lifestyle habits—such as frequent talking, improper breathing patterns, or excessive consumption of caffeinated and alcoholic beverages—can also contribute to dry mouth. Certain medications, including diuretics and antidepressants, may reduce saliva production as a side effect, leading to dryness. Some medical conditions, such as diabetes and Sjögren's syndrome, can directly impair the normal function of salivary glands, resulting in dry mouth. When experiencing symptoms of dry mouth, we should pay attention to our lifestyle habits, medication use, and potential underlying health issues, and appropriately increase fluid intake to help relieve the symptoms.
