A weight-loss injection is set to be offered on the NHS in England to more than a million people considered at high risk of further heart attacks or strokes. Health guidance recommends the treatment for individuals who are overweight and have already experienced serious cardiovascular conditions or circulation problems.

The medication will be prescribed alongside existing treatments, such as cholesterol-lowering drugs, and supported by advice on diet and exercise. Clinical trials involving large numbers of participants have shown the injections can significantly lower the chances of future heart-related events, with benefits appearing even before major weight loss occurs.

The treatment works by mimicking a natural hormone that helps control appetite and slows digestion, making people feel fuller for longer. Patients will be able to administer the injection themselves using a pen device at home. However, some may experience side effects including nausea, bloating or discomfort.

Access to the drug is currently limited to a fixed treatment period, and its long-term effects are still being studied. Experts stress the importance of maintaining physical activity, particularly strength-based exercise, to protect muscle health. The rollout is expected to begin in the coming months, following an agreement to ensure the treatment is cost-effective for the NHS.

New government guidance recommends that children under five should spend no more than one hour a day using screens, while those under two should not use them alone. Parents are encouraged to avoid fast-moving content and instead engage with children during screen time. The advice also promotes “screen swaps”, suggesting activities like reading together or playing simple games, particularly during routines such as mealtimes.

The recommendations are based on emerging research into early childhood development, although experts acknowledge that evidence is still developing. Studies indicate that excessive solo screen use may negatively affect sleep patterns and physical activity, both of which are crucial in early years. However, shared screen experiences with adults may support better learning and understanding.

Parents are also advised to model healthy behaviour, as young children tend to imitate adult habits. With screen use now common from a very early age, families are being encouraged to reflect on their routines and find a balance that works in everyday life, despite the practical challenges this can bring.

Researchers are also examining how modern, fast-paced children’s content may overstimulate developing brains. While technology is difficult to avoid entirely, especially in busy households, the guidance aims to offer realistic, supportive steps rather than strict rules, helping families make more mindful choices around screen use.
