A recent article (AK Kamboj, AS Oxentenko. Clin Gastroenterol Hepatol 2018; 16; 1030-33) provides some useful guidance on bloating.
They describe bloating as an acronym:
- Bowel disturbance (constipation, SIBO, celiac, IBD)
- Liquid (ascites)
- Obstruction
- Adiposity
- Thoracic (overexpansion, diaphragm contraction)
- Increased sensitivity (functional bloating, IBS, dyspepsia)
- Neuromuscular (gastroparesis, impaired accommodation, medications)
- Gas (aerophagia, dietary sources, post-Nissen)
The diagnostic approach they recommend:
- If bloating with diarrhea, evaluate diet, SIBO, celiac, IBD, IBS-D, and medications
- If bloating with constipation, evaluate for constipation, pelvic floor dysfunction, IBS-C, and medications
- If bloating and suspected mechanical disturbance, evaluate for gastric outlet obstruction/small bowel obstruction
- If bloating without bowel disturbance, consider aerophagia, gastroparesis, and functional dyspepsia
Treatment:
- Treat any underlying disorder
- For mild symptoms, reassurance may be sufficient
- Dietary modifications to avoid food triggers & reduce fermentable food products
- Treating constipation when present
- A large number of other treatments can be considered as well including antispasmotics, agents to help with visceral hyperalgesia, cognitive behavioral therapy
My take: I like BLOATING acronym, though the 5 Fs I learned a long time ago is a little easier for me to remember — which include flatus (gas), feces (constipation), fluid, fat, and fetus/masses. Flatus can be caused by swallowing air (aerophagia), malabsorption (celiac, lactose intolerance, parasites), muscular discoordination (abdominal phrenic dyssynergia), and motility problems.”
