Introduction
The occurrence of cholecystitis during pregnancy may be related to hormonal changes causing bile stasis, which can lead to symptoms such as upper abdominal pain, nausea, and vomiting. Changes in bile composition may affect taste perception in the mouth, resulting in a sweet taste. Medications such as atropine sulfate tablets, racemic anisodamine tablets, and phloroglucinol may be used under medical guidance to manage the condition.

Generally, a sweet taste in the mouth accompanied by nausea during early pregnancy may be caused by psychological factors, improper diet, gastroesophageal reflux disease (GERD), hyperemesis gravidarum, cholecystitis, or other conditions. If concerned, it is advisable to seek medical consultation promptly. Detailed explanations are as follows:

1. Psychological Factors

Psychological stress, anxiety, or depressive mood during pregnancy may also cause symptoms such as a sweet taste in the mouth and nausea. Emotional fluctuations can disrupt the balance of the autonomic nervous system, thereby affecting gastrointestinal function and leading to symptoms like nausea and vomiting. Pregnant women are advised to pay attention to their mental health and consider psychological counseling, relaxation training, and appropriate physical activity.

2. Improper Diet

If a pregnant woman consumes excessive amounts of high-sugar foods during early pregnancy, residual sugar in the oral cavity may lead to a sweet taste. Inappropriate eating habits may also worsen feelings of nausea. Adjusting the diet by reducing intake of high-sugar foods and increasing consumption of light, easily digestible foods—such as fresh vegetables and fruits—is recommended.

3. Hyperemesis Gravidarum

Elevated levels of pregnancy hormones may impair normal gastrointestinal function, causing indigestion and excess stomach acid, which in turn leads to nausea and vomiting. Changes in saliva composition or digestive enzyme activity might contribute to a sweet sensation in the mouth. This condition is often accompanied by frequent vomiting, dehydration, and weight loss. Symptoms can be managed through dietary adjustments, such as eating small, frequent meals and avoiding spicy foods.

4. Gastroesophageal Reflux Disease (GERD)

In early pregnancy, hormonal changes can cause relaxation of the lower esophageal sphincter, allowing stomach contents to reflux into the esophagus and mouth, resulting in nausea and a sweet taste. The refluxed gastric acid may also irritate the oral mucosa, intensifying the perception of sweetness. Symptoms may include heartburn, retrosternal pain, and belching. Maintaining regular meal times, avoiding overeating or excessive fullness, and elevating the head of the bed by 15–20 degrees while sleeping can help reduce reflux.

5. Cholecystitis

Pregnancy-related cholecystitis may be associated with hormonal changes causing bile stasis. Bile accumulation can lead to upper abdominal pain, nausea, and vomiting. Additionally, changes in bile components may alter taste perception, resulting in a sweet taste in the mouth. Cholecystitis is commonly accompanied by right upper quadrant abdominal pain, fever, and jaundice. Medications such as atropine sulfate tablets, racemic hyoscine butylbromide, and phloroglucinol may be used under medical supervision to control symptoms.

Pregnant women should maintain a positive and optimistic mindset, follow a balanced diet, engage in moderate exercise, attend regular prenatal checkups, and adhere to professional medical advice to ensure the health of both mother and baby.
