Weight loss injections might one day be as readily available as statins,according to a top health official.
Professor Sir Stephen Powis, the medical director of NHS England, anticipates that these medications will become more affordable and potentially used to prevent various illnesses in the future.

However, chief medical officer Professor Sir Chris Whitty cautioned that these injections are “not a get out of jail card,” emphasizing the continued importance of maintaining a healthy lifestyle.
General practitioners are scheduled to begin rolling out Mounjaro across the UK starting this month.
Currently, these injections cost the NHS approximately £100 each, but prices are expected to decrease over time.
Increasing research indicates that these drugs may offer health benefits beyond diabetes and weight loss, potentially reducing the risks of cancer, dementia, and heart disease.
“These are not get-out-of-jail cards”
statins, which lower cholesterol, have been used for decades to decrease the incidence of heart attacks and strokes and now cost very little, around 3p per pill.
Studies also suggest that statins may reduce the risk of dementia, although this is not their primary purpose.
Prof Powis stated,”The use of statins is now very different from when they first came out and I’ve no doubt that will be the same for these drugs.”
“I think over time it’s highly likely that they will become more widespread.”
“I think there will be a combination of increased evidence of positive outcomes and costs dropping, and we will learn better how to deploy them.”
“It’s not fully unusual for drugs over time to be found to have effects that go over and beyond what they were initially designed for.”
“I am not starry-eyed about weight loss drugs but it’s very exciting.”
“we’re in the foothills of learning how to use them.”
NHS Prescriptions on the Rise
The use of these injections within the NHS is already increasing rapidly. Official figures show that prescriptions in England surged from 1.4 million in 2023 to 2.7 million in 2024.
Doctors spent a total of £269 million on these medications in the latest financial year,and it is estimated that over a million people are purchasing them privately.
Prof Whitty emphasized the importance of individuals continuing to seek support for healthy eating and exercise, in addition to taking medication.
He added: “These are not get out of jail cards.”
“What we shouldn’t do is use it as an excuse, as a society, not to deal with what is a rising and very serious problem.”
Everything you need to know about fat jabs
Weight loss injections are gaining popularity as studies and patient testimonials highlight their effectiveness in promoting weight loss and potentially reducing the risk of serious diseases.
Wegovy and Mounjaro are among the leading weight loss injections available in the UK.
wegovy, known generically as semaglutide, has been available on the NHS for several years, while Mounjaro (tirzepatide) is a newer addition.
Mounjaro is commonly prescribed privately for weight loss and is expected to become an NHS option this year.
How do they work?
These injections work by suppressing appetite, encouraging reduced food intake, which in turn causes the body to burn fat for energy, leading to weight loss.
They mimic a hormone called GLP-1, which signals to the brain when the stomach is full. therefore, these drugs are classified as GLP-1 receptor agonists.
They also slow down digestion and increase insulin production, which lowers blood sugar levels. This is why they were initially developed to treat type 2 diabetes, a condition characterized by high blood sugar levels.
Can I get them?
NHS prescriptions for weight loss drugs, primarily Wegovy and Saxenda (liraglutide), are managed through specialized weight loss clinics.
Typically,patients must 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 these drugs for weight loss purposes.
Private prescribers often offer Mounjaro to individuals who are obese (BMI of 30+) or overweight (BMI 25-30) with a weight-related health risk.
Private pharmacies have faced criticism for dispensing these medications too easily, and now video or face-to-face consultations are mandatory to ensure patients are truthful about their size and health.
Are there any risks?
Yes, side effects are common, but most are relatively mild.
Approximately half of those taking these drugs experience gastrointestinal issues,including sickness,bloating,acid reflux,constipation,and diarrhea.
Dr Sarah Jarvis, GP and clinical consultant at patient.info, noted that a rare side effect is severe acute pancreatitis, which is extremely painful and affects about one in 500 people.
Other uncommon side effects include altered taste, kidney problems, allergic reactions, gallbladder problems, and hypoglycemia.
The impact of these injections on mental health remains inconclusive.
Reports indicate that up to January 2025, 85 patient deaths in the UK were suspected to be linked to these medications.
