Insight | Bloating, Constipation and IBS: What Four Doctors Try First
Robynne Chutkan starts with water, movement, fiber and a look through the medicine cabinet, Rajsree Nambudripad with magnesium, a motility aid and digestive enzymes, and Brennan Spiegel with exercise and posture, while Sara Gottfried reads constipation as a signal of stress, thyroid and hormone trouble. They agree on getting the bowels moving every day and on looking for a cause before settling for a label, but their first steps are not identical.
For bloating, constipation and IBS, the four doctors here start with the same question, how often and how completely you go, and the same aim, a bowel movement every day. Movement is the one first step all of them share. They differ on supplements, on water and on how fast to add fiber.
Warning signs come before any of it. Blood in the stool, weight loss, vomiting, significant abdominal pain or unrelenting nausea are reasons to see a gastroenterologist quickly. Persistent or severe symptoms, and any decision about medicines, supplements or testing, should be taken to a doctor.
Gastroenterologist Robynne Chutkan names her three habits plainly: "it's hydration, it's movement and it's fiber." Movement stimulates the gut's contractions. Her water target is at least half your body weight in ounces of plain water daily. Fiber means plants, working toward 30 or more different plant foods a week. Before treating, she reviews mechanical causes, hormones, motility and above all the medicine cabinet, and says to discuss side effects with the prescriber instead of stopping a drug on your own. She adds that a daily movement does not rule out constipation if evacuation is incomplete.
Rajsree Nambudripad, an integrative physician with gastroenterology training, starts every patient on bedtime magnesium, a ginger and artichoke motility supplement and digestive enzymes while tests are pending. She calls IBS a label for symptoms, not their cause, and cites a figure that about 70 percent of it is caused by small intestinal bacterial overgrowth. She starts fiber slowly with well-cooked greens and moves most water away from mealtimes.
Gastroenterologist Brennan Spiegel calls exercise "the most effective therapy we have for IBS, by far," citing randomized trials. He adds posture and core strength, comparing a slouching gut to a kinked garden hose.
Gynecologist Sara Gottfried treats constipation as a signal. She defines it as anything less than a bowel movement every morning with a feeling of complete evacuation, and asks about borderline thyroid function, perceived stress and the balance of estrogen and progesterone.
They agree on the daily target, that bloating usually starts with constipation, that a name is not an explanation, that the thyroid should be considered, and that stress acts on the gut.
They part ways in four places. Chutkan removes things first and relies on food, water and movement, while Nambudripad starts supplements at once, and neither cites a head-to-head trial. Chutkan and Spiegel set high water targets, while Nambudripad shifts drinking away from meals. Chutkan urges plant variety from the start, while Nambudripad warns sensitive guts need a slow start. And Nambudripad tests at the first visit, while Chutkan and Spiegel act on history and habits first.
Some advice has conditions. Magnesium citrate is for people without kidney disease, and stimulant laxatives are for limited use. More fiber and water can worsen bloating when the problem is a clenched sphincter or a fiber-sensitive gut.
What to do with it: check the red flags first. Aim for a complete movement every day. Move daily and walk after meals. Drink more plain water. Add plants gradually and for variety. Lay out every drug and supplement and discuss gut effects with the prescriber. If you and your doctor agree, try magnesium at bedtime. Do not hold it in. Sit tall and strengthen your back and core. If constipation persists, ask for thyroid tests.
