A WOMAN has revealed she lost eight stone after taking Mounjaro for nine months.
But Alexandra, who is from the UK and currently living in Dubai, claimed she is “annoyed” after experiencing a “very scary” implication after stopping the weight-loss jabs.

Alexandra went from weighing 17 stone 9lbs to 9 stone 7.8lbs thanks to Mounjaro.
Despite slimming down, two and a half weeks after coming off of Mounjaro, Alexandra confessed to rapidly gaining half a stone, which has left her “in such a bad mood”.
This content creator, who has 42,600 followers, shared a short clip with the caption “Well very annoyed today and back on the Mounjaro after a very big weight gain in a very short time. I knew I would have some gain but this is very scary over such a short space of time so back on it, need to make some adjustments for sure.”
She explained: “I was planning on trying to stay off it as long as I could, however, I’ve gained half a stone – it’s taken me five days to gain half a stone that took me two months to lose – the last half a stone I lost was really hard.”
Alexandra confirmed she was 9 stone 7.8lbs but has now gone up to 10 stone 0.8 lbs, leaving her “furious” and “so, so angry”.
My stomach’s also in a lot of pain – I’ve got really bad heartburn

Alexandra added: “It’s put me in such a bad mood, it’s been such a lot of hard work, I don’t really understand how it’s possible that I could have gained half a stone.”
Not only has she gained weight, but she is also experiencing a side effect: “My stomach’s also in a lot of pain – I’ve got really bad heartburn, which is just something I don’t normally have.”
Alexandra went onto reveal she ate Five Guys and had a Sunday dinner, but hadn’t “eaten crazy”, so didn’t understand where the weight gain had come from.
The young woman, who was left feeling “really angry”, confessed that although she feels “disappointed” and “embarrassed”, she now plans to continue injecting.
As well as this, she shared: “I probably need to work on my fitness a little bit more as well before I come off.”
Social media users react
The TikTok clip, which was posted under the username @alexandraindubai, has clearly left many open-mouthed, as it has quickly gone viral and racked up 1.2 million views.
It’s also amassed 11,900 likes, 1,430 comments and 3,682 shares.
I fear this is the issue with Mounjaro – if major lifestyle changes are not made during the losses then you are trapped within a never ending cycle of injecting

Social media users were left stunned by Alexandra’s claims and many raced to the comments to share their thoughts.
One person said: “This is the trouble when coming off it unfortunately.”
Another added: “Exactly the same thing happened to me. I’m back on it.”

A third commented: “I fear this is the issue with Mounjaro – if major lifestyle changes are not made during the losses then you are trapped within a never ending cycle of injecting.”
At the same time, someone else wrote: “Thank you for being honest.”
Sun GP Dr Zoe Williams says fat fabs can save the lives of people with “life-threatening levels of obesity”.
But despite this, the NHS website warns: “Never take an anti-obesity medicine if it has not been prescribed to you. These types of medicines may not be safe for you and can cause serious side effects.”
About half a million Brits use weight loss drugs – and that number is expected to double in the next year.
Mounjaro is said to suppress the appetite, making people feel fuller for longer.
Everything you need to know about fat jabs
Weight loss jabs are all the rage as studies and patient stories reveal they help people shed flab at almost unbelievable rates, as well as appearing to reduce the risk of serious diseases.
Wegovy – a modified version of type 2 diabetes drug Ozempic – and Mounjaro are the leading weight loss injections used in the UK.
Wegovy, real name semaglutide, has been used on the NHS for years while Mounjaro (tirzepatide) is a newer and more powerful addition to the market.
Mounjaro accounts for most private prescriptions for weight loss and is set to join Wegovy as an NHS staple this year.
How do they work?
The jabs work by suppressing your appetite, making you eat less so your body burns fat for energy instead and you lose weight.
They do this my mimicking a hormone called GLP-1, which signals to the brain when the stomach is full, so the drugs are officially called GLP-1 receptor agonists.
They slow down digestion and increase insulin production, lowering blood sugar, which is why they were first developed to treat type 2 diabetes in which patients’ sugar levels are too high.
Can I get them?
NHS prescriptions of weight loss drugs, mainly Wegovy and an older version called Saxenda (chemical name liraglutide), are controlled through specialist weight loss clinics.
Typically a patient will have to have a body mass index (BMI) of 30 or higher, classifying them as medically obese, and also have a weight-related health condition such as high blood pressure.
GPs generally do not prescribe the drugs for weight loss.
Private prescribers offer the jabs, most commonly Mounjaro, to anyone who is obese (BMI of 30+) or overweight (BMI 25-30) with a weight-related health risk.
Private pharmacies have been rapped for handing them out too easily and video calls or face-to-face appointments are now mandatory to check a patient is being truthful about their size and health.
Are there any risks?
Yes – side effects are common but most are relatively mild.
Around half of people taking the drug experience gut issues, including sickness, bloating, acid reflux, constipation and diarrhoea.
Dr Sarah Jarvis, GP and clinical consultant at patient.info, said: “One of the more uncommon side effects is severe acute pancreatitis, which is extremely painful and happens to one in 500 people.”
Other uncommon side effects include altered taste, kidney problems, allergic reactions, gallbladder problems and hypoglycemia.
Evidence has so far been inconclusive about whether the injections are damaging to patients’ mental health.
Figures obtained by The Sun show that, up to January 2025, 85 patient deaths in the UK were suspected to be linked to the medicines.
Such injections are licensed for patients with type 2 diabetes and to assist those who are clinically obese – with a Body Mass Index of 30 or over.
One jab is administered each week but the duration is dependent on a person’s weight.
The drugs can be lawfully supplied only when prescribed by a practitioner – like a doctor, nurse or a pharmacist-independent prescriber.
But many are now buying them through online pharmacies with insufficient checks.
Earlier this year, figures from the Medicines and Healthcare products Regulatory Agency revealed fat jabs had been linked to 82 deaths across the UK.
And the family of a man from Burton upon Trent, Staffs, who died after taking Mounjaro are calling for a probe into the jab’s “potential to kill”.
