A MOTHER has revealed that she lost four stone on Mounjaro but claimed it has ruined her life for good.
Zari, who was a size 18 to 20 before using the fat jabs , has now been able to slim down thanks to the popular injections , but it hasn’t been without consequences.
The content creator , who is keen to share an insight into the “aftermath of taking Mounjaro ” claimed that now, she is in and out of hospital constantly.
Not only has she had to have numerous blood tests to find out what is wrong with her, but she’s also in unbearable pain too.
Posting on social media , Zari, who “hated” the way she looked in pictures before resorting to Mounjaro , filmed herself whilst in her pyjamas , as she opened up on her recent diagnosis.
Alongside her clip, the mother wrote: “As much as I love Mounjaro , I can hands down say it has ruined a part of me. I’ve never had gastritis in my life but now I do.”
Zari claimed that she has been diagnosed with gastritis, which is when the lining of your stomach becomes inflamed.
Gastritis can cause pain, indigestion and feelings of nausea and symptoms include tummy pain, vomiting, burping and farting.
According to the NHS website , causes of gastritis can include infections with a bacteria called helicobacter pylori; taking anti-inflammatory painkillers and aspirin; drinking too much alcohol and being very stressed and unwell.
Zari confirmed that she was able to lose four stone in the space of four months whilst using the fat jabs , but claimed that Mounjaro has “ruined my life for good.”
She added: “I look trash because I’m tired from the pain the whole night – Mounjaro has given me gastritis and I’m gonna be honest with you, that is a killer.
“It’s been two months, I’ve been going in and out of hospitals, getting drips and everything.
“When [the pain] comes, it is so bad. If I eat anything, if I don’t eat anything, whatever it is, it affects my day to day life.”
Clearly in discomfort, Zari continued: “The pain is so bad and so unbearable – it’s a sharp, shooting pain and I’ve never had it in my life, but thanks to Mounjaro , I have it.
“I can’t blame Mounjaro because it helped me lose the weight, but I think it’s giving me side effects for the long term.”
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.
Experts reveal all
Following Zari’s claims, Fabulous spoke to the experts to get more information on why this mother may be experiencing such an adverse reaction to Mounjaro.
Dr Tom Curtis, Clinical Head of Obesity at Voy , told Fabulous: “It is concerning and important to hear about severe patient experiences like this. While an individual’s story can be powerful, it’s helpful to place it in the context of what was seen in the large-scale clinical trials involving thousands of people.
“The trial data consistently shows that the most common side effects of Mounjaro are gastrointestinal – specifically nausea, diarrhea, vomiting, and indigestion. These are the main reasons why some people in the studies chose to stop taking the medication.
“While the official trials don’t use the specific medical term ‘gastritis,’ the symptoms they list are exactly what can lead to a diagnosis of gastritis or severe stomach inflammation in a real-world setting. The studies note that these side effects were typically ‘mild to moderate’ and most often occurred when patients were starting the drug or increasing their dose.
The pain is so bad and so unbearable – it’s a sharp, shooting pain
Zari
“However, a ‘typical’ experience in a trial doesn’t mean a severe one is impossible. A severe case of these known side effects, particularly persistent vomiting, could certainly lead to serious complications and the need for hospitalisation.
“What this patient has described, while not the most common outcome, represents a severe reaction that falls within the known risk profile of the drug.
“It carries a well-documented risk of gastrointestinal side effects that can be very challenging and, in some individuals, severe. However, for the majority, it appears that the medication is safe and well tolerated.”
What are the other side effects of weight loss jabs?
Like any medication, weight loss jabs can have side effects.
Common side effects of injections such as Ozempic include:
Nausea: This is the most commonly reported side effect, especially when first starting the medication. It often decreases over time as your body adjusts.
Vomiting: Can occur, often in conjunction with nausea.
Diarrhea: Some people experience gastrointestinal upset.
Constipation: Some individuals may also experience constipation.
Stomach pain or discomfort: Some people may experience abdominal pain or discomfort.
Reduced appetite: This is often a desired effect for people using Ozempic for weight loss.
Indigestion: Can cause a feeling of bloating or discomfort after eating.
Serious side effects can also include:
Pancreatitis: In rare cases, Ozempic may increase the risk of inflammation of the pancreas, known as pancreatitis, which can cause severe stomach pain, nausea, and vomiting.
Kidney problems: There have been reports of kidney issues, including kidney failure, though this is uncommon.
Thyroid tumors: There’s a potential increased risk of thyroid cancer, although this risk is based on animal studies. It is not confirmed in humans, but people with a history of thyroid cancer should avoid Ozempic.
Vision problems: Rapid changes in blood sugar levels may affect vision, and some people have reported blurry vision when taking Ozempic.
Hypoglycemia (low blood sugar): Especially if used with other medications like sulfonylureas or insulin.
As well as this, Dr Ghazala Aziz-Scott, a senior NHS GP, said to us: “Mounjaro can be a game changer for patients in the right situation and with on-going blood tests and monitoring.
“However, there are some very serious long term side effects that require prompt medical attention such as pancreatitis, gastritis and gall bladder inflammation, all of which can present with abdominal pain.
“There is also a potential increased risk of certain cancers like thyroid and kidney.
“Patients on Mounjaro or other GLP-1s need to be aware of these potential red flags and seek urgent medical evaluation.”
Social media users react
Zari’s TikTok clip, which was posted under the username @ zayreeshh , has clearly left many open-mouthed, as it has quickly racked up 349,100 views, 3,050 likes and 561 comments.
Social media users were shocked to hear about Zari’s experience with fat jabs and many eagerly raced to the comments to express this.
Not only this, but other Mounjaro users also opened up on their struggles since using the injections.
That pain is a pain I’ll never forget. I had to have my gallbladder removed because of MJ

One person said: “Too quick, too fast, is no good.”
Another added: “Sorry to hear this, hope you feel better soon.”
A third commented: “Me seeing this the night after going hospital for the exact same thing lol.”
Whilst someone else shared: “I had the same pain after Mounjaro . I got Pancreatitis, the pain was too bad…”
Not only this, but another fat jab user wrote: “That pain is a pain I’ll never forget. I had to have my gallbladder removed because of MJ.”
The reality of Mounjaro
As well as Zuri’s health battle since using Mounjaro, last year it was revealed that Scots nurse Susan McGowan , 58, died after taking low-dose injections of the fat jabs over a fortnight.
A probe also found that nearly 400 people have gone to hospital after taking weight loss drugs .
The common side effects include nausea, vomiting and diarrhoea, which can lead to severe dehydration.

Not only this, but doctors say they have also seen “life-threatening complications”, including seizures, bowel obstruction and inflammation of the pancreas.
Model Lottie Moss , 27, even said she had a seizure after taking high doses of Ozempic .
The makers of Mounjaro, Lilly UK , said patient safety is its “top priority”.
Lilly UK stressed: “Regulatory agencies conduct extensive independent assessments of the benefits and risks of every new medicine and Lilly is committed to continually monitoring, evaluating, and reporting safety data.
“If anyone is experiencing side effects when taking any Lilly medicine, they should talk to their doctor or other healthcare professional.”
