Why this happens so often at work
Workplaces are a common setting for well-meaning but unwelcome comments about weight change — "you look great, what are you doing?" is a common opener that puts you in the position of deciding, often on the spot, how much to share with someone who isn't a close friend or family member.
You control the level of detail
None of these responses are wrong — pick based on your relationship with the person and your own comfort level:
- Minimal: "Thanks! Just some health changes." — a complete, natural-sounding answer that closes the topic without inviting follow-up.
- Redirect: "I appreciate that — how's your week going?" — shifts the conversation without addressing the comment directly at all.
- Partial share: "I've been working with my doctor on some health stuff" — acknowledges there's a reason without naming the medication.
- Full share: if you're comfortable and the relationship warrants it, sharing that you're on a GLP-1 medication is entirely your choice to make.
If a comment feels inappropriate rather than just awkward
Comments about your body, especially from someone in a position of authority (a manager) or delivered repeatedly despite a clear deflection, cross from casual into potentially a workplace conduct issue. It's reasonable to address this more directly ("I'd rather not discuss my body at work") or involve HR if it continues.
If you're asked directly by a manager
You are generally not obligated to disclose medical information to a manager unless it relates to a workplace accommodation you're requesting. A simple "it's a personal health matter" is a complete and appropriate boundary.
The bottom line
You get to decide how much of this story belongs at work — a range of honest, low-effort responses exist for casual comments, and you're entitled to set a firmer boundary if comments feel inappropriate rather than just curious.
This is peer information, not medical advice — decisions about your treatment and what you share at work belong with you and your clinician.
