How long does it take to recover from breathing issues after stopping metformin? - #29797

I can't breath fully after metformin. I used metformin without prescription 40 tablets over 7 months. Blood tests are normal. Stopped medicine after feeling unwell 3 weeks ago. Will i recover fully?

I am a general dentist with 3+ years of working in real-world setups, and lemme say—every single patient teaches me something diff. It’s not just teeth honestly, it’s people… and how they feel walking into the chair. I try really hard to not make it just a “procedure thing.” I explain stuff in plain words—no confusing dental jargon, just straight talk—coz I feel like when ppl *get* what's going on, they feel safer n that makes all the difference. Worked with all ages—like, little kids who need that gentle nudge about brushing, to older folks who come in with long histories and sometimes just need someone to really sit n listen. It’s weirdly rewarding to see someone walk out lighter, not just 'coz their toothache's gone but coz they felt seen during the whole thing. A lot of ppl come in scared or just unsure, and I honestly take that seriously. I keep the vibe calm. Try to read their mood, don’t rush. I always tell myself—every smile’s got a story, even the broken ones. My thing is: comfort first, then precision. I want the outcome to last, not just look good for a week. Not tryna claim perfection or magic solutions—just consistent, clear, hands-on care where patients feel heard. I think dentistry should *fit* the person, not push them into a box. That's kinda been my philosophy from day one. And yeah, maybe sometimes I overexplain or spend a bit too long checking alignment again but hey, if it means someone eats pain-free or finally smiles wide in pics again? Worth it. Every time.

Hello

Metformin itself usually doesn’t cause lasting breathing problems once stopped, so 3 weeks is already longer than expected for simple drug-related side effects to settle. Most people would feel normal within a few days to 1–2 weeks after stopping.

However, the symptom “can’t breathe fully” needs attention. Rarely, metformin can be linked to Lactic Acidosis, but that typically causes severe illness (rapid breathing, weakness, vomiting) and abnormal blood tests—so if your tests are normal, that’s less likely.

More common possibilities are anxiety-related breathing pattern, gastritis/acid reflux causing chest discomfort, or an unrelated lung/heart issue.

You should not ignore this since it’s persisting—get a clinical check (oxygen levels, chest exam, possibly ECG or chest X-ray). The good part is that this is usually reversible, and most people do recover fully once the actual cause is identified and treated.

If you develop worsening breathlessness, chest pain, dizziness, or fainting, go to emergency care immediately.

Take care Feel free to talk
