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.
Despite Chloe's concerns, there is currently no scientific evidence directly linking Mounjaro to an increase in

Why Does Hair Loss Happen?
Hair loss can be influenced by so many factors, from genetics and hormone changes to lifestyle choices.
Stress, diet, and even hair care habits can all impact hair strength.
It's perfectly normal to lose some hair each day, but sometimes the body can shed more than usual, responding to things like hormonal shifts or even life stressors.
Why It Happens More This Time of Year
Have you ever noticed your hair seems to shed more in autumn? That's seasonal shedding!
During summer, we hold onto extra hair to protect our scalp from the sun.
As the weather cools, it's like our body recalibrates and lets go of those extra strands.
Dry, cooler air can also make hair more brittle, making it easier to lose a little extra volume during these months.
Hacks and Affordable Buys to Treat Hair loss
The great news? You don't need to spend a fortune on pricey treatments to support your hair.
Try daily scalp massages—they're so simple but really help boost blood flow to the follicles.
Castor oil is another fantastic, budget-friendly option that's rich in nutrients to strengthen your strands.
Adding a bit more protein to your diet and a biotin supplement can also work wonders for overall hair health.
Products to Avoid
Steer clear of products with high levels of alcohol, sulphates, and parabens - they can be drying and damage hair over time.
Heat styling and chemical treatments can also cause breakage, so try to use them sparingly.
Instead, look for gentle, hydrating formulas to support your scalp and keep hair healthier through the seasons.
But at the same time, one user clarified: 'It's not Mounjaro!! It's the weight loss, it will grow back.'
Meanwhile, another agreed: 'Hair loss means you aren't eating enough.

I can't shift pink marks on my skin – they keep popping up but I can't get a GP appointment
OUR resident specialist and NHS GP, Dr Zoe Williams, shares her expert advice. Today, 2 Dr Zoe Williams helps Sun readers with their health concerns Credit: Olivia West 2 A reader sent in an image of their rash Credit: supplied Q) I HAVE some skin marks that I first noticed last year. I tried to see my doctor but could only get a phone consultation which, as you can imagine, was useless. They wanted me to email a picture, but I couldn't access the site. I've used a steroid cream, which I had for a different issue, and found it makes the marks go, but after a while, more appear elsewhere. They aren't sore or itchy, but this is really getting me down. Can you help? A) Thank you for sending the images of the rash, which appear to show oval salmon-pink-coloured patches on your torso. While seeing images of skin is helpful, we doctors usually need to get a history from the patient in order to make a diagnosis. I would like to know if, prior to the rash appearing, there was a single larger patch that came up first. If this was the case, then that would likely be the herald patch – a sign of the harmless skin condition pityriasis rosea. Most read in Health It usually gets better on its own over the course of around four to ten weeks. You say you first noticed skin marks a year ago, but I'm unsure if there was a period in between where it cleared. This could be a second episode of it. If this sounds likely, it will resolve on its own and a mild steroid cream can alleviate any discomfort if there is any. If you do not think it is this, then you need a consultation with a GP. Sun Health Explainer: Skin rashes - eczema, psoriasis, sepsis TIP : As we enjoy the summer, try to refrain from wearing sandals and flip-flops too often. Their lack of support can lead to calluses, corns and issues like plantar fasciitis, which causes heel pain. Send your questions for Dr Zoe to: health@
