Prescriptions for Mounjaro jabs, to help people lose weight, will be available at GP surgeries in England from today - but only for those who meet very strict criteria.

Mounjaro, originally a diabetes drug, aids significant weight loss by curbing appetite and improving insulin sensitivity. Weekly injections offer sustained results but come with potential side effects and high costs.

“The medication comes with a patient information leaflet listing common side effects, including feeling sick, indigestion, constipation, and diarrhoea. There can be some more serious side effects, such as low blood sugar, gallstones and inflammation of the pancreas (pancreatitis).
