A mother who used Mounjaro to try and improve her looks after a break-up ended up with severe health issues.
Jane Fennah, 39, jumped on the GLP-1 train and ordered some of the medication, intended for use by those with type 2 diabetes, to lose some weight.
But in line with the many celebrities that have shared their weight-loss progress due to the jabs, the mum decided to give Mounjaro a go.
She splashed £170 on the jab from an online pharmacy in February 2025 and managed to lose four stone in just five months.

While increasing her dose and further suppressing her appetite in an attempt to achieve the 'revenge bod' she was after, Jane said her urine turned brown and she started to suffer with diarrhoea and a 'stabbing' pain in her chest.
Believing she was having a heart attack, the mother rushed to hospital to be told following some tests that she had gallbladder stones.
After being hospitalised for nine days, she is now waiting to undergo surgery to have her gallbladder removed.

As well as this, Jane, from Blackpool, was told that she had liver blockage and blood clots, while her eyes started to turn yellow.
Explaining that it hurt to inhale and that she was unable to sit down, health professionals told her to stop using the jab.
The information leaflet for Mounjaro warns that gallstones are a common side effect which can affect around one in 10 people.
Now, she vows to stick to the gym for her weight loss journey, explaining that she was 'losing weight quite quickly'.
"I had no side effects other than the normal ones of the jab like feeling sick. I did what people said, drank plenty of water, and took my vitamins," Jane explained.

Despite getting 'really bad diarrhoea' when upping her dose to 5mg, she increased it once again to 7.5mg after seeing online that others experienced the same thing.
Believing her brown urine was down to dehydration, the mum explained: "I thought I might have a bug because I have kids in school. That went on for about two weeks and I started to get bad indigestion in the middle of my chest.
"It started hurting my back and I had to walk bent over, I couldn't stand straight, I couldn't sit down."
Recalling getting a CT scan to check her heart when she thought she may have been dying, Jane was told that she wasn't the only one in A&E who was taking the 'skinny jab'.

She said: "They put me straight in blood thinners, they said I had blood clots but my gallbladder was so inflamed they couldn't see it...
"I thought I was going to die because I wanted to lose weight. It was horrific."
Jane, who also lost hair as a result of the jab, thought her exhaustion was down to her everyday tasks as a mum.
Now, she is urging others to be aware of the fine print with these jabs, admitting that 'it's not worth it' and that it's too easily accessible online.
"When I split up with my partner last year I thought I need to sort myself out and it will help me because everyone is on it and I've seen so many success stories," Jane said of her decision to buy Mounjaro in the first place.

Claiming that she 'won't touch any weight loss thing again', the 39-year-old aims to lead a healthy and balanced lifestyle instead.
She highlighted: "There needs to be more tests before people get them, it shouldn't be so easily accessible.
"People don't understand that not everyone is going to suffer these complications but there's a lot of people who are. It's scary, it's not worth it."
A spokesperson for Lilly, the manufacturers of Mounjaro, said to LADbible: "Patient safety is Lilly’s top priority. We take any reports regarding patient safety seriously and actively monitor, evaluate, and report safety information for all our medicines.
"The Mounjaro (tirzepatide) Patient Information Leaflet warns that gallstones is a common side effect when used for weight management.
"We encourage patients to consult their doctor or other healthcare professional regarding any side effects they may be experiencing and to ensure that they are getting genuine Lilly medicine."
