Talking to Patients About Weight-Loss Drugs

The use of weight-loss drugs such as GLP-1 receptor agonists (e.g., semaglutide, tirzepatide) has increased rapidly in recent years. These drugs can help some people achieve significant weight reduction, but they are not suitable for everyone and require careful counselling before starting treatment. By discussing benefits, risks, practicalities, and  uncertainties, clinicians can help patients make informed, realistic decisions about their treatment.

Key points to discuss with patients

1. Indications and eligibility
These drugs are usually licensed for adults with a specific BMI. They should be used alongside lifestyle interventions such as dietary change, increased physical activity, and behaviour modification.

2. Potential side effects – some can be serious
Common adverse effects include nausea, vomiting, diarrhoea, and abdominal discomfort. Less common but more serious risks include gallstones, pancreatitis and visual problems. Patients should know what to watch for and when to seek urgent medical advice.

3. Loss of muscle mass as well as fat
Treatment often leads to loss of both fat and lean tissue (muscle). Reduced muscle mass can affect strength, mobility, and metabolic rate. Encourage resistance exercise and adequate protein intake to help maintain muscle.

4. Long-term safety and unknowns
While clinical trials show substantial short- to medium-term benefits, we do not yet have decades of safety data for newer agents. Patients should be aware that some long-term effects remain unknown.

5. Need for sustained treatment
For many, continued use is required to maintain weight loss. This raises issues around cost, availability, and the practicality of long-term therapy.

6. Likelihood of weight regain after stopping treatment
Most people regain much of the weight lost when medication is discontinued unless lifestyle measures are sustained.

7. Impact on mental health and eating behaviour
Changes in appetite can be beneficial but, rarely, may lead to problematic eating patterns. Monitoring for disordered eating is important.

8. Contraindications and drug interactions
Caution is needed in people with a history of pancreatitis, certain gastrointestinal diseases, or relevant endocrine tumours. Review other medications for potential interactions.

9. Monitoring requirements
Ongoing follow-up is essential to assess weight, metabolic health, nutritional status, muscle mass, and side effects.

Protecting Against the "Quad-demic": Influenza, Covid-19, Norovirus and RSV

As the NHS braces for a challenging winter season, it is grappling with a "quad-demic" of health emergencies caused by influenza, Covid-19, norovirus, and respiratory syncytial virus (RSV). This confluence of viral threats poses a significant risk to public health in the UK as well as putting strain on healthcare resources, emphasising the importance of preventive measures to safeguard public health. Public health measures such a vaccination and good personal hygiene are pivotal in reducing the impact of these illnesses, particularly for vulnerable groups. The Four Viruses: What Are They? Influenza: A highly contagious respiratory infection that causes significant illness each winter. It can lead to severe complications, particularly in the elderly, young children, pregnant women, and those with chronic health conditions. Covid-19: Though its most acute phase has passed, Covid-19 remains a concern, especially as new variants of SA...

MPH Student Presentations on the NHS Care.Data Programme

As part of a session on primary care data in the Health Informatics module on the Imperial Master of Public Health Programme, I asked students to work in two groups to present arguments for and against the NHS Care.Data programme. Care.Data is an NHS programme that will extract data from the medical records held by general practitioners (GPs) in England. The Care.Data programme takes advantage of the very high level of use of electronic medical records by GPs in England. After extraction, data will be uploaded to the NHS Health and Social Care Information Centre (HSCIC). The data will then be used for functions such as health care planning, monitoring disease patterns and research. The programme has been controversial with proponents arguing that the programme will bring many benefits for the NHS and the population of England; and opponents arguing it is a major breach of privacy. You can view the two presentations to help inform you further about these arguments: Arguments fo...

The Hidden Cost of Cheaper NHS Contracts: Losing Community Trust

NHS budgets are under considerable pressure. It is therefore unsurprising that many NHS Integrated Care Boards (ICBs) In England will aim to prioritise price in contract awards, But this approach is a significant threat to community-centred healthcare. While competitive tendering is a legally required, an excessive focus on costs in awarding NHS contracts risks overshadowing key factors such as established community trust, local expertise, and the long-term impact on continuity of care. This shift towards cheaper, often external, commercial providers threatens to cut the links between communities and their local health services. The argument that competitive tendering is solely about legal compliance, and not cost, is undermined by the very nature of such tendering, which by design encourages the lowest bid. This approach risks eroding the social fabric of local healthcare provision, where established relationships and understanding of specific community needs are essential. Establishe...
