[2026 update] Sulphur-smelling eructation: mechanism and what helps

Posting this under the heading it deserves: Sulphur-smelling eructation: mechanism and what helps Everything below is what sits behind that.

I have read the maintained page on this and I still have a gap, so I am asking rather than guessing.

Context: semaglutide, 18 weeks in, currently at a dose I reached by the standard four-week steps. Everything below is my own record rather than anything a clinician told me.

The specific question is the one in the title. What I have already checked: the labelling summary on the relevant documentation page, the two most-linked topics in this subcategory, and my own notes from the last 9 weeks. What I could not find is whether the answer changes at higher doses or whether it is the same arithmetic throughout.

If the answer is "it depends", I would rather know what it depends on than be given a number.

Recognition and grading: nausea ranges from "noticeable" to "limiting". Constipation ranges from mild to severe. Having language to describe the magnitude helps you track whether something is worsening or stable and helps your clinician understand what you are reporting.

For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.
