Dry mouth at night may be caused by diabetes or kidney disease, or it could result from hyperthyroidism or oral mucosal disorders. It might also be due to dehydration or a dry environment. In daily life, drinking more water can help maintain adequate hydration. If symptoms persist, it is recommended to visit a正规 hospital to determine the underlying cause and receive appropriate treatment.
