Big effect

Curcumin cut gastrointestinal symptoms in women with severe obesity — a significant drop on the GSRS scale (p = 0.002) — but the finding comes from a small pilot study in a specific clinical population, so it may not apply broadly.

This is an early signal that curcumin might help with gut discomfort in people with severe obesity, but with only one small trial so far, the evidence is too thin to act on confidently.

In a 13-week double-blind trial, women with severe obesity who took 1,500 mg/day of curcumin reported fewer gastrointestinal symptoms like burping and constipation compared to those on a placebo. The effect was statistically significant and moderate in size, but because this was a pilot study with a narrow population, the results need to be replicated before they can be generalized.

Where this fits in the evidence

This is among the first studies we've indexed on Turmeric for Reduced Gastrointestinal Symptom Rating Scale Total Score — treat it as an early signal until more research accumulates.
