What causes bloating and a big belly despite eating more but defecating less, and what should be done about it?
Eating a lot but having infrequent bowel movements along with an enlarged abdomen may be related to functional dyspepsia, gastrointestinal motility disorders, intestinal obstruction, or other causes. Patients can receive treatment through dietary adjustments, oral medications, surgery, etc. Specific analyses are as follows:
1. Functional Dyspepsia
Functional dyspepsia is usually caused by dysfunction of the stomach and duodenum. Patients may experience symptoms such as upper abdominal pain, feelings of fullness, bloating, and reduced bowel movements. A light diet is recommended, and patients should avoid spicy, raw, or cold irritating foods to prevent worsening of symptoms. When necessary, medications such as domperidone tablets or mosapride citrate tablets may be taken under medical guidance.
2. Gastrointestinal Motility Disorder
In patients with gastrointestinal motility disorders, normal digestion and absorption of food cannot occur, causing food to remain in the intestines and leading to constipation, bloating, and abdominal distension. Patients may take medications such as Bacillus subtilis bivalent live bacterial granules or probiotic powders as directed by a physician.
3. Intestinal Obstruction
Intestinal obstruction refers to the inability of intestinal contents to move normally through the digestive tract due to various causes, resulting in retention of gastric contents in the intestines and symptoms such as abdominal distension, constipation, and reduced gas passage. In some cases, surgical intervention may be required under medical advice, such as adhesion lysis or correction of intestinal volvulus.
Besides the common causes mentioned above, conditions such as intestinal polyps or rectal tumors may also be responsible. If patients experience additional discomfort symptoms, they should visit a hospital for evaluation and receive targeted treatment accordingly.
