What causes dry mouth at ten weeks of pregnancy?

Dry mouth at ten weeks of pregnancy may be caused by hormonal changes, inadequate fluid intake, upper respiratory tract infections, gestational diabetes, Sjögren's syndrome, or other factors. Symptoms can be improved through hydration, dietary adjustments, and medication. If dry mouth persists or worsens, or is accompanied by excessive thirst, frequent urination, or fever, prompt medical attention is recommended.

1. Hormonal changes: During pregnancy, elevated levels of estrogen and progesterone can affect salivary gland function, reducing saliva production and causing dry mouth, typically without other significant discomfort. It is recommended to drink warm water in small amounts frequently throughout the day, avoiding large volumes at once, to maintain oral moisture.

2. Inadequate fluid intake: Increased metabolic rate during pregnancy means that insufficient daily water intake—or reduced fluid consumption due to morning sickness—can easily lead to dry mouth. It is advised to consume 1500–2000 milliliters of fluids per day, supplemented with light soups, porridge, fresh vegetables, and fruits to boost hydration.

3. Upper respiratory tract infection: Reduced immunity during pregnancy makes women more susceptible to viral or bacterial infections such as the common cold, which may present with dry mouth along with nasal congestion, sore throat, and mild cough. Follow medical advice when using medications such as Isatidis Radix Granules, Pudilan Anti-inflammatory Oral Liquid, or Cefixime Dispersible Tablets to relieve symptoms.

4. Gestational diabetes: Changes in insulin sensitivity during pregnancy can lead to elevated blood glucose levels, resulting in osmotic diuresis, excessive fluid loss, and subsequent dry mouth. This condition is often accompanied by increased thirst, frequent urination, and abnormal weight gain. Under medical supervision, treatment may include Insulin Injection, Metformin Tablets, or Gliclazide Modified-Release Tablets to manage symptoms.

5. Sjögren's syndrome: An autoimmune disorder that impairs salivary gland function, leading to dry mouth, often accompanied by dry eyes and nasal dryness. Under a doctor’s guidance, treatments may include Sodium Hyaluronate Eye Drops, artificial saliva, and Hydroxychloroquine Tablets to alleviate symptoms.

Maintain appropriate indoor humidity, avoid spicy and dry foods, rinse the mouth with warm water after meals, maintain regular sleep patterns and avoid staying up late, engage in moderate walking to improve physical health, and practice gentle self-care to relieve dry mouth discomfort.
