The biggest pros and cons to consider before taking weight loss jabs
In the 90s and 00s, slimming clubs were packed with people looking to shed the pounds.
Flash forward to today however, and Weight Watchers has filed for bankruptcy, as the meteoric rise of weight loss jabs saw the company struggling to compete.
Medications like Ozempic, Mounjaro, Wegovy and Rybelsu, previously used to treat diabetes, have exploded in popularity in recent years.
An estimated 500,000 Brits are now taking either Mounjaro or Wegovy (both of which are available on the NHS) and Simple Online Pharmacy claims demand is growing by up to 40% each month.
However, health secretary Wes Streeting warned that they shouldn't be seen as a quick 'cosmetic' fix, adding: 'These are serious medicines and should only be used responsibly and under medical supervision.'
So if you're considering weight loss jabs, we've compiled everything you need to know, as well as a look at the biggest pros and cons…

Administered as weekly jabs, these drugs – often called GLP-1 agonists – mimic the hormones our bodies release when we eat to help diabetics manage insulin levels.
But alongside regulating blood sugar, they also help with reducing appetite (so you feel less hungry throughout the day) and increasing feelings of fullness (so you eat less when you do).
In the UK, new rules mean you'll need to have a consultation with a specialist weight management service before being prescribed this kind of treatment.
This can be done through the NHS or privately, with the likes of Superdrug and Boots offering prescriptions online.
Metro asked Dr Suzanne Wylie, GP and medical adviser for IQdoctor, about the biggest pros and cons of weight loss injections. In terms of their benefits, here's what she had to say:
Weight loss
Unsurprisingly, weight loss drugs help you lose weight — but the amount is impressive, with studies showing patients typically see at least a 10% to 15% weight reduction.
'This can be transformative, especially for those with long-standing obesity where lifestyle interventions alone have failed,' says Dr Wylie.
Reduction in obesity-related health issues
Dr Wylie explains: 'Weight loss of this magnitude is associated with a meaningful drop in the risk of type 2 diabetes, hypertension, sleep apnoea, and non-alcoholic fatty liver disease.
'There's also early evidence suggesting improved cardiovascular outcomes, even independent of weight loss. And for patients with pre-diabetes, these medications may delay or prevent progression to full-blown diabetes.'
Improved quality of life and mental health
Beyond the physical benefits, Dr Wylie says the 'positive impact on self-esteem and mood' caused by weight loss 'can create a virtuous cycle, making it easier to stay engaged with other aspects of health promotion, such as physical activity and social participation.'
Support for patients who feel stuck
According to Dr Wylie, the helping hand these jabs provide can be a major boost for those who feel they've 'tried everything' without success.
She adds: 'As GPs, it's empowering to have another tool to offer that feels both compassionate and effective.'
Despite their benefits, there are a number of things to consider before taking weight loss drugs – including possible short-term and long-term side effects. Here's a look at what Dr Wylie considers the biggest downsides:
Side effects
'Gastrointestinal side effects are common, particularly during dose escalation,' she says, noting that these can include nausea, vomiting, diarrhoea, and constipation.
Dr Wylie also adds than in rare cases, 'there's a risk of pancreatitis or gallbladder issues.'
Weight loss drugs aren't something to mess around with – one side effect colloquially termed 'Ozempic face' is symbolic of that. But what is it? And what are the dangers of taking semaglutide incorrectly?
This phenomenon refers to sagging, ageing and lacklustre appearance of the facial skin and structures,' according to Dr Adil Sheraz, consultant dermatologist and British Skin Foundation spokesperson.
He said: 'The face has a layer of fat that essentially stretches the skin. Ozempic results in rapid weight loss and does so very effectively. This, of course, will lead to rapid loss of subcutaneous (under the skin) facial fat.
'The overlying skin however will not be able to shrink at the same rate, resulting in a sagging, droopy and wrinkled appearance.'
Dr Paul Jarrod Frank, a dermatologist in New York thought to have coined the phrase, told the New York Times he's started seeing Ozempic face 'every day' since these drugs hit the mainstream.
He said: 'A 50-year-old patient will come in, and suddenly, she's super-skinny and needs filler, which she never needed before. I look at her and say: 'How long have you been on Ozempic?' And I'm right 100 per cent of the time.'
This isn't necessarily specific to Ozempic. As Dr Sheraz explains, this change in facial features can occur with any type of rapid weight loss.
There are other potential complications to look out for too: Ozempic-style weight loss drugs were recently linked to symptoms of depression and suicidal ideation, as well as an increased risk of vision loss.
More worryingly, at the end of last year, the government issued a warning after 10 people died and 68 were admitted to hospital as a result of using the injections.
More than 7,000 reports of illness associated with the drugs had also been made, leading the Medicines and Healthcare products Regulatory Agency (MHRA) to publicly state they should not be used for 'unauthorised indications such as aesthetic weight loss'.
Long-term use
Unless you overhaul your habits, the results you see while taking these medications won't last long afterwards. More Trending
'Once stopped, weight regain is common unless there's been a concurrent and sustainable lifestyle change,' says Dr Wylie.
Costs
Only 'very specific patient groups' are entitled to weight loss jabs on the NHS, and 'privately, these medications are expensive, often over £200 a month.'

AI foot scanner could keep people with heart failure out of hospital
The device, which is roughly the size of a smart speaker, operates in a similar way to facial recognition by taking and analysing almost 2,000 pictures a minute to calculate the level of fluid in the feet and ankles. This water retention, known as oedema, is one of the three major warning signs that heart failure is becoming severe and potentially life threatening. The AI scanner is able to trigger an alert to healthcare professionals so they can take action, such as increasing their patient's medication. The Foot Study, which is being presented at the British Cardiovascular Society annual conference in Manchester, suggests these alerts come 13 days before a person would end up in hospital. It involved 26 heart failure patients from five NHS trusts who were enrolled between 2020 and 2022. They were monitored using the AI device and were also asked to weigh themselves using Bluetooth-enabled scales. Seven instance of worsening heart failure was detected in six patients, while one death from the condition was recorded. Researchers found that, in patients enrolled in the study for at least two weeks before an alert was triggered, the average lead time before hospital admission was 13 days. The lead time averaged eight days when all five triggers picked up by the device were analysed. The study also found that monitoring using the scales failed to predict any heart failure-related hospital admissions. Researchers suggested this is because patients struggled to stick to tracking their weight, whereas the AI device did not require any action. Dr Philip Keeling, senior author of the study and a consultant cardiologist at Torbay and South Devon NHS Foundation Trust, said: 'Only about half of people admitted to hospital with heart failure currently get assigned an early review by a heart failure nurse who can check to see if they are suffering a harmful build-up of fluid because their heart is not working properly. 'Amid a shortage of heart failure nurses, a device like this can be like a virtual nurse, tracking people's health.' The device, developed by Cambridge-based start-up Heartfelt Technologies, is mounted to the wall and is typically installed at a patient's bedside. It uses AI technology to detect a person's foot and lower leg and track their position, so a camera can take 1,800 pictures a minute from multiple angles. These images reveal the volume of fluid in the foot and lower leg. It works without wifi, and only scans the legs to a height of 50cm from the floor. Heart failure is a long-term condition that means the heart is unable to pump blood around the body properly, usually because the heart has become too weak or stiff. Is it estimated that more than a million people are living with heart failure in the UK. The three main symptoms that indicate the condition is getting worse are increased breathlessness, weight gain and swelling in the legs or ankles. Dr Keeling added: 'Living with heart failure can be overwhelming, with all the medications, medical tests and appointments, and the requirement to monitor your own health. 'This scanner, once it is installed, just automatically keeps an eye on you and alerts the heart failure nurse, which is a huge relief.' At the end of the study, 18 of the 22 surviving patients kept the AI device. Reacting to the findings, Professor Bryan Williams, chief scientific and medical officer at the British Heart Foundation (BHF), said: 'This small study suggests a simple device could significantly improve outcomes for at-risk patients with heart failure by keeping them out of hospital. 'This study is a good example of how technology might aid earlier interventions and treatment, by allowing people to track a key sign of their heart health at home. 'Innovations with the potential to transform heart care in this way are a major part of the BHF's goal to save and improve lives of people living with cardiovascular disease.'
