Why do I feel bloated all the time and my stomach enlarged?
Short answer: Persistent bloating and a visibly enlarged stomach commonly come from excess intestinal gas, chronic constipation, food intolerances (e.g., lactose, FODMAPs), or conditions like IBS, SIBO, celiac disease, hormonal changes, or fluid accumulation (ascites). If the change is new, severe, or accompanied by weight loss, blood, vomiting or breathing problems, seek medical evaluation promptly.
Explanation
Bloating is a symptom (feeling full, pressure) and distention is measurable enlargement. Gas buildup results from swallowed air, fermentation of carbohydrates by gut bacteria, or slowed gut motility. Constipation stretches the abdomen; SIBO or malabsorption produce excess gas. Hormonal shifts (e.g., ovarian/pelvic issues, menopause, or PMS) can cause fluid retention and bloating. True enlargement can also be from increased abdominal fat or fluid (ascites) due to liver, heart, or malignancy. Diagnosis may include history, physical exam, stool tests, blood tests (including celiac serology), breath tests for SIBO, imaging (ultrasound/CT), and endoscopy if indicated. Red flags that require urgent workup are severe or progressive pain, unexplained weight loss, gastrointestinal bleeding, persistent vomiting, or new shortness of breath.
Tips
- Keep a food and symptom diary and try a short low-FODMAP elimination under guidance to identify triggers.
- Avoid carbonated drinks, chewing gum, and eating too quickly to reduce swallowed air.
- Manage constipation with fiber adjustments, hydration, and regular physical activity.
- Consider breath testing for SIBO or lactose intolerance if symptoms persist despite diet changes.
- Seek medical evaluation for persistent symptoms or any red-flag signs to get appropriate testing and treatment.
