The causes of morning dry and bitter mouth may involve multiple factors:
1. Physiological factors: For example, improper diet, such as consuming spicy, greasy, or high-salt foods at night; or poor environmental conditions, such as sleeping in an overly hot or dry environment, which may lead to body dehydration.
2. Pathological factors: Conditions such as gastroesophageal reflux disease (GERD), diabetes mellitus, and hyperthyroidism may cause symptoms of dry and bitter mouth. For example, patients with poorly controlled diabetes might experience elevated blood sugar levels at night, leading to dry and bitter mouth upon waking.
3. Oral hygiene: Poor oral hygiene with food residue and bacterial buildup in the mouth may also result in a bitter and dry mouth.
It is recommended to maintain healthy lifestyle habits, pay attention to oral hygiene, and adjust diet and environmental factors. If symptoms persist or worsen, timely medical consultation and treatment are advised.
