Insight | Bloating, Constipation and IBS: What Four Doctors Try First
October 6, 2026 · 14 min read
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.
The rules, numbers and steps worth keeping in front of you.
- Red flags needing a prompt medical visit: blood in the stool, weight loss, vomiting, significant abdominal pain, unrelenting nausea.
- Chutkan, Nambudripad and Gottfried: the target is a complete bowel movement every day.
- Chutkan: three first habits are hydration, movement and fiber.
- Chutkan: drink at least half your body weight in ounces of plain water daily.
- Chutkan: aim for 30 or more different plant foods a week.
- Chutkan: review every prescription, over-the-counter drug and supplement, and talk to the prescriber before changing anything.
- Chutkan: if more fiber and water make you more bloated, a holding pattern may be the cause. Ask about biofeedback therapy.
- Nambudripad: bedtime magnesium, a ginger-based motility supplement and digestive enzymes while tests are pending.
- Nambudripad: start fiber slowly with well-cooked leafy greens, and space meals four to five hours apart without snacking.
- Spiegel: exercise is the most effective therapy for IBS. Fix slouching and strengthen back and core.
- Gottfried: constipation is a signal. Ask about thyroid, hormones and perceived stress.
- Nambudripad: any constipated patient should have thyroid labs checked.
- Conditions: magnesium citrate only without kidney disease, and stimulant laxatives only for limited use.
This is the short form. The full insight has every expert's reasoning, their own words and the sources.
