There is a sensation of gas moving around in the lower abdomen when lying flat.

　　The lower abdomen refers to the abdominal area. When lying flat, the sensation of gas moving around in the abdomen may be caused by gas accumulation, impaired intestinal motility, indigestion, somatization disorder, gastroenteritis, or other reasons. This can be alleviated through daily care and medication. If bodily discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:

　　1. Gas accumulation: Excessive gas buildup in the gastrointestinal tract may lead to abdominal discomfort, possibly due to eating too quickly or consuming gas-producing foods that cause bloating. It is advisable to avoid rapid eating, reduce air intake, and avoid high-gas-producing foods such as legumes and carbonated beverages.

　　2. Impaired intestinal motility: Lack of physical activity may result in sluggish intestinal movement, causing gas to stagnate in the intestines and leading to discomfort. Increasing dietary fiber intake and maintaining adequate hydration can promote intestinal motility and help relieve this condition.

　　3. Indigestion: Overeating may lead to indigestion, prolonging food retention time in the gastrointestinal tract and producing gas, accompanied by symptoms such as abdominal pain and bloating. Avoid excessive food intake; medications such as Simo Tang oral liquid, Domperidone tablets, or Compound Pepsin Capsules may be used under medical guidance.

　　4. Somatization disorder: This is a non-organic condition caused by autonomic nervous system dysfunction, in which patients may experience abdominal pain, bloating, and abnormal intestinal movements. Treatment may include medications such as Compound Diazepam tablets, Estazolam tablets, or Alprazolam tablets, as prescribed by a physician.

　　5. Gastroenteritis: Often related to consuming contaminated food, pathogen infection may also cause abnormal gas accumulation in the intestines, accompanied by symptoms such as abdominal pain and diarrhea. Patients may take anti-infective medications such as Ciprofloxacin Hydrochloride Capsules, Bismuth Potassium Citrate Tablets, or Enteritis Ning Granules under medical supervision.

　　During recovery, excessive tension and anxiety should be avoided. Practicing relaxation techniques such as meditation and deep breathing can help improve emotional well-being and support the body’s return to normal function.
