A YOUNG woman went from a size 18 to a 10 after using fat jabs, but has experienced 10 less than ideal side effects.
Bethany Diana, 27, lost six stone in just nine months after using Mounjaro, but experts and NHS medics warn about the dangers of taking such medications without a prescription.

The brunette beauty who is from the UK, confirmed that as a result of taking Mounjaro, which is regarded by some as the King Kong of weight loss jabs, she has experienced bad breath and diarrhoea.
Not only this, but she’s also battled eggy sulfur burps, as well as hair loss.
Posting on social media, Bethany, who recently revealed that she now has ‘Mounjaro booty’, wrote: “Some of my side effects since being on Mounjaro.”
She then confirmed that as well as battling with constipation and diarrhoea, she has had to deal with the dreaded sulfur burps, which have left her with bad breath.
Sulfur burps, or burps with a rotten egg smell, occur due to the presence of hydrogen sulfide gas in the digestive tract.
Many Mounjaro users have confessed to suffering from such burps, which have been described as “absolutely disgusting”.
Not only this, but Bethany claimed that she has also lost hair since using Mounjaro.
And that’s not all, as she has also experienced nausea, heartburn, wind, and reflux.
The tenth side effect Bethany has experienced is appetite suppression, which is a direct implication of using Mounjaro, which works by making you feel fuller for longer.
Despite the 10 side effects Bethany has been faced with, she beamed: “But on the plus side I did lose six stone in nine months and I am such a better version of myself.”
Sun GP Dr Zoe Williams claimed that Mounjaro, which could soon be rolled out on the NHS, can save the lives of people with “life-threatening levels of obesity”.
But despite this, the NHS warned: “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.”
And this isn’t the first time Bethany has been candid about her Mounjaro journey, as she previously claimed that she decided to use the injections after spending her “whole adult life wanting nothing but to be skinny”.
Bethany was fed up of feeling “insecure” and initially topped the scales at 15 stone 12 lbs, but after less than a year, lost six stone.
The content creator claimed that alongside using Mounjaro, she was also calorie counting and “only started exercising after the majority of the weight had gone”.
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.
The TikTok clip, which was posted under the username @bethanydianax, has clearly left many open-mouthed, as it has quickly racked up 107,400 views, 438 likes and 53 comments.
Numerous other Mounjaro users eagerly flocked to the comments, keen to share the side effects they have experienced whilst using fat jabs.
One person said: “I had my first jab yesterday and the nausea this morning was unreal! Reminded me of being pregnant.”

Another added: “I can’t handle the nausea and loose bowels!”
A third commented: “It’s the sulfur burps and the feeling of nausea which I cannot stand, especially when I’m hardly eating anything to cause it.”
Meanwhile, someone else asked: “Anyone got a bruised stomach? I didn’t on the first three injections but I have on the last two.”
Be aware of the dangers
In addition to nasty side effects, those debating whether to begin using Mounjaro should know that it can also have fatal consequences.
The injections are licensed for patients with type 2 diabetes and are administered every seven days.
They are also available to assist those who are clinically obese (with a Body Mass Index of 30 or over).
The drugs, which have been widely regarded as ‘fat jabs’, can be prescribed by a practitioner – such as a doctor, nurse or a pharmacist-independent prescriber.
But increasingly, we are seeing more and more people buying them through online pharmacies, without sufficient checks.
Not only this, but recently, figures from the Medicines and Healthcare products Regulatory Agency revealed that fat jabs had been linked to 82 deaths across the UK.
Following the death of a man from Burton upon Trent, Staffs, who died after taking Mounjaro, his family are now calling for a probe into the jab’s “potential to kill.”
