Mounjaro and abdominal pain

39 replies

yellowblue20 · 09/05/2024 17:11

I started mounjaro last Friday (6 days ago). No side effects for the first 2 days, had a fever on the 3rd day (put this to over exertion as I did around 4 hours of exercise the day before) and for the last 2 days I’ve had abdominal pain. I’ve also had some nausea and diarrhoea which is to be expected.

I was concerned about the abdominal pain, it feels like my stomach is sore and it’s just under my rib area.

I saw my GP today who had no clue what mounjaro even was and was not happy I had taken it. He booked me in for a blood test tomorrow and told me to stop taking it. he said pancreatitis can present as abdominal pain and it’s on the rare side effect list.

has anyone else experienced similar abdominal pain? Feeling really gutted because I was hoping that I could use this to finally lose some weight (BMI 35).

I know I should listen to my GP and stop taking it but he didn’t even know what it was until he googled it for 2 minutes.

has anyone else had similar pain?

Yes, but that’s why it’s only prescribed for people who are very obese - like any medication it’s benefits vs side effects.
Obesity is a major factor in every major disease and loosing weight reduces that risk enough to take the risk of the other side effect of the drug overall

This and also there have been no cases of thyroid cancer in humans. It was in rodents this was observed.

its not a drug for cosmetic weight loss but as an aid in cases of obesity, which carries extremely real and proven risks of life threatening conditions

And people are turning to private prescriptions because NHS weight management services are SHIT

@DownWithThisKindOfThing second this!
called GP finally ready to ask for help and broke down about my weight. Was called in for bloods which appear ‘normal’ but said that I wouldn’t qualify for saxenda through my areas WMS criteria (My BMI is 35!). He said he would refer me to them anyway, that was 2 months ago. I’ve taken matters into my own hands and gone private, my financial worry is worth it compared with my mental health about getting my weight under control.
@yellowblue20 Hopefully the side effects will ease for you and you get blood results that give you piece of mind, let us know how you get on? I’d suggest joining an MJ specific group too, I’ve found them a wealth of support and encouragement x

I had been eating very little, a protein shake and a healthy meal of meat and veg if I could manage that.

I did have some takeaway Chinese one day which may have caused and added to all this although I didn’t eat much of it at all

my next dose was supposed to be yesterday but I’ve not taken anything. Think I’m too scared to take another dose and GP told me not to!

shame as I lost 2kg this week

If you feel too worried to take the next dose that’s fine to not take while you think about this moving forward, there is a lot of information out there about the jabs, I can’t say how much is factual etc, probably not many (if any) people on mn can, most of us who take it can only say our own experiences. I’m a little shocked your go hasn’t heard of this, maybe another gp in your surgery has though, might be worth a second opinion. Saying this as gps are human, once had one prescribing me anti reflux baby milk for my twins, another one was refusing saying it’s not available on prescription as you can buy it, once I asked him to check the book they have he saw it was there and did prescription

I had very bad abdominal pain on day two. It was trapped air. Try massaging left to right in the area that hurts. If it makes you burp then it might just be gas.

Your diet really matters on this. Having any large meal, or anything fried/greasy or spicy or in my case lots of gassy veggies (broccoli and cabbage) can cause side effects.

I agree you should check it out to be on the safe side. The first week is the worst though.

All these things. Diet is super important, greasy, fatty foods, very carby or spicy etc can have unpleasant side effects. You need to stick to bland foods, chicken breast, veggies, plain fruit like apples, and some fibre to prevent constipation.
You need to contact your prescribing doctor OP - they are best placed to guide you.

Are you sure it's not gallbladder, that's pain under the ribs and into the back and is a known side effect of any quick weight loss regime

The op is only in week one or two so if it's gall stones it won't be from rapid weight loss yet.
It could be existing gall stones flaring up though - the pain does sound quite similar

And as for the comment made by a PP about OP expecting the NHS to bail her out - yes, and?

The NHS is there to treat people who need it. Drug addicts get “bailed out” as was so charmingly put by the NHS. Fat people can’t win it seems. Get vilified for sucking up NHS resources because we are fat, NHS weight management services are non existent to crap, when people do what they are asked and take responsibility for their own health they still get vilified.

I've been on Mounjaro for 10 weeks and have learned what I can and can't eat. I'm now on 7.5mg and have had some side effects from the beginning at 2.5mg however, I have suffered from IBS since I was a teen so I'm already acutely aware of my gut and used to problems so it can be difficult for me to identify what might be IBS and what might be the Mounjaro. This is what works for me so far and it may be useful for anyone else starting out on this journey.

What works for me is;

Eating small portions and stop eating the moment I feel satisfied rather than full.

Avoiding acidic foods such as tomato based sauces, curries, chocolate and wine! I can sometimes eat these a couple days before my next dose when the effects of the injection is wearing off but its a big no for me for the first few days. The heartburn can be horrendous!!

Reducing highly processed food and increasing the amount of fibre and protein I eat has helped. The protein is particularly important as our bodies will happily lose muscle over fat. I tend to eat a small portion of porridge if I feel like eating breakfast with some honey and Chia seeds.

I usually eat my last meal before 6pm. I find that if I eat later, I won't sleep well and make up feeling like I have a hangover.

DearSleepycat · 14/01/2025 03:24

I tried this didn't realise how bad the side effects were. Lasted two injections then I've stopped. I literally woke up in my sleep with agonising stomach pain, sulphur burps and vomitting. Paracetamol did not help at all with managing the pain I've had to take off many days off work becausd I'm in so much pain.

Will never try this again I'm still recovering at the moment. And it's almost been a week since my last injection. That stuff can go straight in the bin. I haven't had such bad stomach pain since I gave birth.

Halloweenniks · 23/02/2025 14:50

I have taken one 2.5 mg injection and followed the instructions. The first few hours I felt really thirsty but that was about it, happy days I thought. Next morning, bad GI pain and had to force myself to eat anything as quite honestly I didn't want to make things worse but then thought follow the plan and eat which I did which may elevatw the pain, which it did for a brief time. Felt a bit nauseated but ginger lozenges hwlpws with that. Day 2, 3,4 the same with a very uncomfortable, hard, swollen stomach.
I am at day 5 and feel a bit better but constipated. It was a hard decision to try this method of weight loss but after a lot of research and given personal experiences I gave it a go. I have made the decision not to contiue, just as hard as starting as well as accepting the loss of money and the waste but I don't want to lose 2/3 days after each injection. I do have a small Hiatus Hernia which may have been a catalyst. However, I do not regret trying as I am in a routine of drinking more water which I needed to do and has given me the kick up the bum to lose the weight. I don't know how much I have lost...I ll know tomorrow and update.
It currently hasn't been for me but I wish everyone the best of success in their journey.

Not been in it long enough for that…
OP pop over to the weight loss pages on MN there is a specific one for jabs where you can get advice without the sneering!
Your GP sounds like an idiot, BTW.

Drylogsonly · 23/02/2025 14:57

I have been taking Mounajro for 8 weeks, lost 14 lbs and am sticking at 5mg rather than going up because of side affects BUT it has been nice changing for me.
as others have said - stick to small healthy meals - chicken salad, fruit & yoghurt etc and it should calm down.

Yup. Posters can FUCK right off with this nonsense. Mounjaro is the drug that the NHS is apparently going to offer to all obese people soon… and OPs GP never having heard of it seems unlikely to me.
While you can order Mounjaro privately one of the conditions of the online prescription is that your GP is informed. My NHS record shows the prescriptions.
