Possible causes of dry mouth during pregnancy may include the following: 1. Hormonal changes: During pregnancy, hormone levels—especially estrogen and progesterone—increase. These hormonal fluctuations may reduce saliva production, leading to dry mouth. 2. Increased fluid needs: Metabolism speeds up during pregnancy, increasing the body's demand for water. Insufficient fluid intake can easily result in dry mouth. 3. Vitamin deficiencies: Pregnant women need to supply nutrients to the fetus. Deficiencies in vitamins such as B, C, and E may also contribute to dry mouth. 4. Environmental factors: Hot weather or prolonged use of air conditioning can cause dry indoor air, which may lead to dry mouth in pregnant women. To help relieve dry mouth during pregnancy, it is recommended that pregnant women maintain adequate fluid intake, eat more foods rich in vitamins, and appropriately adjust indoor humidity levels. If symptoms persist or worsen, prompt medical evaluation is advised.
