A WOMAN who weighed 12st 10lbs and was a size 16 decided to try the weight loss jab after struggling to stick to diets, but things weren't as perfect as she'd hoped.
Kathleen Smith, 40, bought Mounjaro privately and lost 10 pounds in two weeks but immediately starting noticing the side effects – heartburn and digestive issues.
But the mum-of-three thought she just had to “ride it out” and kept taking the jab for a further five months.
After taking Mounjaro for three months she started getting dizzy and would have and started to notice she was losing clumps of her thick .
She would also have “disgusting” sulphur burps which she said were so bad her boyfriend, 50, would have to leave the house.
She consulted her GP and was told her folic acid levels were low and came off the jab in February but is still having dizzy spells and hair loss.
Eli Lilly – who make Mounjaro – list diarrhea, indigestion and decreased appetite as possible side effects of the jab.
Kathleen, a full time carer for her eldest child, from Telford, Shropshire, said: “Every time I put my hands through my hair it feels like I have got an undercut.”
She continued: “I still have dizzy spells if lean down doing the laundry. I wouldn't recommend it.”
The mum explained that despite her massive weight loss, the jabs are “not worth it.”
“We don't know what damage we're doing to our organs,” she said.
Kathleen had previously tried different diets to lose weight but would find she would get “comfortable” and the weight would creep back on.
As a busy mum she would often snack throughout the day – going through six bags of crisps and always have a chocolate bar with her cup of tea.
She decided to give Mounjaro ago to help to reduce her appetite and her cholesterol.
Kathleen started taking the jab in September 2024 but had side effects within two days.
She said: “Within two days there was liquid coming out my bottom end.
“I had really bad heartburn. I had no hunger whatsoever. I'd go to the loo eight to nine times a day.”
But Kathleen had seen others talking about their experiences on and felt encouraged to “ride it out.”
I noticed my hair was coming out in the brush. When I go in the shower the sinkhole was getting blocked.
She was also encouraged by her weight loss and her Fitbit stats.
She said: “I was seeing the numbers on Fitbit.
“I'm a visual person so I was seeing all the red and yellow and wanted to get it to green – despite all the side effects.”
Kathleen started getting dizzy spells and blackouts in December 2024.
She said: “If I was squatting down when I would stand up all the blood rushed to from my head to my legs and a black cloud would go over my eyes.
“My head would drop and I would have to sit down and wait for it to pass.”
Not only that, but Kathleen also struggled with sulphur burps, which she said were “disgusting”.
“My boyfriend was like ‘I'm going back to my house', the stench was grotesque,” she said.
It even go to the point were the mum would have to go outside if she wanted to burp.
Things went from bad to worse in December when she started loosing hair.
She said: “I have always had really thick hair.
“I noticed my hair was coming out in the brush. When I go in the shower the sinkhole was getting blocked.”
Kathleen went to go and see her GP in February and her blood tests revealed she had low folic acid levels and low iron.
She decided to come off Mounjaro – despite losing 3st 4lbs and dropping to 9st 6lbs and a size 10.
Kathleen spent £860 on the jab in five months.
She said: “The comments from my family were saying I looked really ill.”
Since stopping Kathleen has still struggled with dizziness and hair loss – but her other symptoms have subsided.
Her old habits have come back and she's found herself snacking again.
She has put on stone since being off and is now 10st 7lbs.
Kathleen said: “My old habits were muted.
“I wouldn't go back on it.”
Eli Lilly said: “Patient safety is Lilly's top priority.
“We take any reports regarding patient safety extremely seriously and actively monitor, evaluate, and report safety information for all our medicines.
