What Causes Dry Mouth and Bitter Taste in the Morning?
Waking up in the morning with a dry and bitter mouth may be caused by insufficient water intake, poor oral hygiene, mouth breathing, gastritis, hepatitis, and other factors. Appropriate measures can be taken based on the specific causes.
1. Insufficient water intake: After a night's sleep, the body loses water through respiration and perspiration. If water intake was inadequate the previous day, it may lead to a dry and bitter mouth upon waking. It is recommended to drink sufficient water during the day and have an appropriate amount of water before bedtime.
2. Poor oral hygiene: Not brushing teeth thoroughly before bedtime may leave food debris and bacteria in the mouth, which can ferment and produce unpleasant odors, resulting in a dry and bitter mouth upon waking. It is recommended to maintain good oral hygiene habits, brush teeth thoroughly before bedtime, and use proper brushing techniques such as the Bass method.
3. Mouth breathing: Some individuals breathe through their mouths while sleeping, causing excessive evaporation of moisture in the oral cavity, leading to a dry and bitter mouth in the morning. It is recommended to adjust sleeping posture, avoid sleeping on the back as much as possible, and adopt a lateral position, which may help reduce mouth breathing.
4. Gastritis: Gastritis may be caused by bacterial infection, environmental factors, etc., leading to abnormal gastric acid secretion, which may result in symptoms such as dry mouth, stomach pain, and bitter taste upon waking. It is recommended to take medications such as复合凝乳酶胶囊 (compound rennet enzyme capsules) and枸橼酸铋钾片 (bismuth potassium citrate tablets) under a doctor's guidance to improve these symptoms.
5. Hepatitis: Hepatitis may be associated with environmental factors and infections, which can affect bile secretion and excretion. Bile stasis may manifest as symptoms such as dry mouth and bitter taste. Patients may follow medical advice to use medications such as安络化纤丸 (Anluoxian capsules) and双环醇片 (Bicyclol tablets) to alleviate discomfort.
If experiencing any discomfort, it is recommended to visit a hospital promptly and follow medical instructions for treatment.
