Why do health professionals still reject idea that HRT makes you gain weight?

Every doctor/expert article I've read states HRT won't make you gain weight and in fact you're more likely to lose it, because the lifting of brain fog/more energy makes you want to eat better and exercise more.

Yet if you read menopause forums so many women anecdotally say the opposite. I'm 53 and I've just come off HRT after being on it for four years. At the beginning it did help with brain fog and other symptoms but I also gained 2.5 stone and felt constantly bloated, particularly during the 12-day oral progesterone cycle. My boobs became so dense, in fact, that the breast clinic had trouble doing a mammogram and so I decided to come off it because I was worried about the breast cancer risk.

Since stopping last month I've lost 8lbs without trying and my appetite has reduced massively. Before, I felt hungry all the time. Now I get that the chances are my medication had become unbalanced and I may have developed a sensitivity to progesterone, but the only thing I've done to change my diet to lose weight is come off HRT. Yet according to health professionals HRT wasn't responsible for me gaining weight in the first place.

Why do they make out there's no link between weight gain and HRT when there's so much anecdotal evidence that says otherwise? Is it because they know women might baulk at taking it if it was a listed side effect?

Well, NOT being on HRT makes you gain weight, as part of menopausal chances.

MotherMary14 · 28/09/2025 13:10

That’s not been my experience, hence my post. I had put a little weight on while in peri and before I went on HRT, but I have got much fatter on it!

I think there is an aspect of individual responses but in research they didn't find weight gain was a factor.

Before, I felt hungry all the time.

Were you eating more because of that?

Dense breasts exist without HRT, although HRT can make some women's denser. It's very individual.

Twoshoesnewshoes · 28/09/2025 13:26

OP my GP agreed with me immediately that I had gained weight due to HRT and said it’s not uncommon.
I experimented twice, coming off and back on HRT - it was definitely the HRT.

I never gained weight as part of menopause changes but I always did on the contraceptive pill so I suspect it depends how you respond to different hormones - it’s clear to me from the huge variation in menopause experiences that the genes/lifestyle/hormone interactions are complex

Pezdeoro41 · 28/09/2025 13:31

I've just come off HRT for this reason. I've actually had medical professionals agree that it does. In fact it's listed as a possible side effect on Evorel and Oesteogel now so I think the research saying there's no evidence is a little out of date. Yes ok you might gain with menopause anyway but if it's a case of going on it, immediately putting on X pounds, and coming off it and immediately losing them then it's obviously that.

Yes, I did eat more because my appetite rocketed while on HRT. Now I'm off it, I'm eating like a normal person – i.e. when I'm hungry.

As for dense breasts – I'm a G Cup and have breastfed, so no, they weren't exactly dense before. HRT made them denser.

Exactly! It's not uncommon, yet medical experts insist there is no correlation. Good for your GP for being more enlightened.

I didn't know it's been added as a side effect – I wonder when that happened. I also agree that weight gain in menopause is likely, but the rate I'm losing now leaves me in no doubt that the bulk of my weight gain in the last four years has been down to HRT. I've never lost weight so easily!

Edited to add: if the manufacturers are now acknowledging it, hopefully the rest of the medical profession will catch up. My symptoms weren't too bad in peri and now I wish I'd tried to get through menopause without HRT, because carrying an extra 2.5 stones at my age brought related health issues that I'd much rather have avoided.

I haven't gained weight on HRT. But I weight train. I wonder if that helps.

LuxuryWoman2020 · 28/09/2025 15:42

I've lost weight on HRT as my appetite is lower and I have energy to exercise more.

Sugarahhoneyhoney · 28/09/2025 16:01

I certainly put on weight whilst using Utrogestan. But it was less fat, more serious bloating and breast swelling.

On month 4 I spotted what was happening and dropped to 1200 cals for 3 weeks, lost all the bloat and then switched to the Mirena and no more issues. It was definitely the progesterone for me.

Sugarahhoneyhoney · 28/09/2025 16:03

And in response to pps who mentioned exercise, I also lift weights and have done since early 30s so no, being a regular exerciser doesn't ward off the weight gain for some women.

Bizarrely I found myself eating left over ready made custard packets from Xmas one day in March, I couldn't get enough cals and sugar into me while on utro. I also suspect that the excessive tiredness it caused didn't help.

Mirena doesn't have the same side effects at all.

HappyByTheRiver · 28/09/2025 16:11

3 of my friends are on it and have all lost between a few pounds and a stone so I don’t think it causes weight gain.

I’m not on it but I’m peri menopausal and have reduced my calories to around 1700 a day, I used to be able to eat closer to 2000. I think it’s menopause itself that causes weight gain so you need to reduce the calories and/or exercise more if you want to not put on weight.

I know lots of women who feel crap with menopause symptoms so they don’t move as much and comfort eat.

Pezdeoro41 · 28/09/2025 16:11

Yeah I weight train and do hot yoga, frankly I've been doing more exercise and eating better than ever and it's not made the blindest bit of difference. I only came off it a week or so ago so we'll see how it goes but I know it's that at least partly - when I upped my dose I immediately put more weight on again and my breasts got larger (which I hate, they're big enough as it is 😂) . It certainly doesn't cause weight gain in everyone, no one is saying that, but it is common. I also had the same issue with the combined pill. I'm on Mirena rather than oral progesterone so it's not that either.

MeridaBrave · 28/09/2025 16:26

That hasn’t been my experience. I didn’t have an oral progesterone cycle though as I have a mirena. So no bloating.

Yes, that’s the point I am trying to make - not everyone will gain weight on it but when health professionals claim there is no link at all it’s frustrating to read.

I came off it for this exact reason. The way you describe feeling - particularly dense breasts, bloated and hunger - was exactly my experience.

CameForAVacationStayedForTheRevolution · 28/09/2025 17:20

I put on 7lbs in 2 weeks on hrt. My diet and exercise hadn’t changed in that time 🤷🏻‍♀️. Stopped taking it and the 7lbs came off in a few weeks. GP said it must be my cycle/hormones or that I’d eaten more. I hadn’t

limescale · 28/09/2025 17:28

Hasn’t “middle age spread” been a thing long before HRT?

limescale · 28/09/2025 17:32

I have not looked at the research but is it not true that there is no proven link between HRT and weight gain? Obviously individual experiences don't make that research false.

I am fortunate so far to have not had too difficult a time of menopause, have not taken HRT and my weight has not changed - if anything it seems to have settled at the lower end of the range I've been all my adult life (which is a healthy weight).

Oh there's correlation alright, but less evidence for causation. Hrt use correlates with general ageing, slowing down, maybe drinking more etc etc.

But yes, I put on loads of weight and really struggled getting it off afterwards!

If you Google “does HRT cause weight gain” the answer is an overwhelming no.

I am a scientist and want to look deeper than Google e.g. recent peer reviewed articles in PubMed. Cooking a roast at the moment!

PocketSand · 28/09/2025 18:11

I think it depends on the HRT. My GP upped my progesterone to 200 mgs and I immediately gained 5kg despite not changing diet or exercise. I can’t reduce it or they will reduce oestrogen which I need for bone density.
