First of all, a big well done on your progress so far. It’s great that you’re already thinking about long-term goals and maintenance.

You’ve raised an important point. Weight regain is common, not just after using medication, but after many types of diets or lifestyle changes. That’s because weight is influenced by many things, including our genes, hormones, habits, and environment.

These treatments have been available for over twenty years for diabetes and have given many people hope because they don’t just help with weight - they can also support things like blood sugar, joint pain, or liver health. However, with any approach, the best long-term results come when healthy habits are built in at the same time, like healthy eating, regular movement, and sleep.

Scientists are still learning about how medications can help in the long-term treatment of obesity, including for weight maintenance. Some people may continue using them longer term under medical supervision if they’ve found them helpful in managing their weight and health.

As for the media attention, headlines tend to focus on rare side effects without contextualising the numerous benefits seen or citing the serious health risks linked to obesity. As with any healthcare plan, this is individual to you and your own body. It is important to always consult a doctor or pharmacist to understand the benefits and side effects for you. Reading the research is a good first step to ensuring you are equipped with clinically validated information.

What’s clear is that your journey is valid. You’ve found something that works for you, and that’s something to be proud of. Stay consistent and be kind to yourself as your body and mind adjust.

Hi @Kentishbirdlife Side effects are common, though not everyone will get them. Most side effects tend to happen when first starting treatment or when the dose increases, and they usually get better on their own as your body adjusts. Some very common ones include feeling sick (nausea), vomiting, diarrhoea, constipation, and stomach pain. These happen because the treatment slows down how quickly food moves through your body. This helps you feel fuller for longer, but it can also make your tummy feel unsettled. If you’re ever worried about side effects or they don’t go away, it’s a good idea to speak to your provider. We also have an overview of side effects here.

Hi @Glasgowgal200 It is great to hear you are thinking about your health and the options available for you.

As these treatments are prescription-only medications, a full clinical review is needed to decide what is safe and appropriate. The best next step is to complete a consultation, and a healthcare professional can look at your overall health and support you in exploring safe options.

Hi @Cheddarcheeseandsodabread Thank you so much for sharing your story. It sounds like you have been through a lot, and it is positive to hear that your mental health is in a better place now.

Managing weight after menopause or while living with Type 2 diabetes can be especially challenging. You are certainly not alone in feeling that way.

Be kind to yourself - you have clearly worked hard to get where you are, and that deserves real credit.

Hi @ThankULord It's great that you are being proactive about your health.

In general, weight loss medications are licensed for people with a BMI of 30 or more, or a BMI of 27 and above if there’s a weight-related health condition such as type 2 diabetes or high blood pressure. Some groups, depending on ethnicity, may have different BMI cut-offs based on health risk.

These treatments are prescription-only, so a healthcare provider would need to do a full clinical assessment to determine if they’re suitable and safe in your case. The best next step is to complete an online consultation to explore what might be appropriate for you.

I would like to know this as I have Gallstones

Hi @nocoolnamesleft Thank you for sharing your journey.

Hi @Facescar77 Fatty liver disease is one of several conditions linked to excess weight. While we can’t determine individual eligibility here, this is something that could be explored through a consultation, where a qualified healthcare professional will assess your medical history and overall health.

On cost, you’re not alone in feeling the strain. These treatments can be expensive while still under patent, and we know affordability is a barrier for many. Some people find they spend less on snacks, takeaways, or other extras once their appetite changes, which can help offset some of the cost, but we know it’s still a stretch for many.

Hi @ethelredonagoodday @TwoBigNoisyBoys @ThumbTowers @Turmerictolly @Dizzywizz and @Kitkatcatflap

Hi @Wimin123 Great question - and one that comes up more often as people reach their goal weight.

Loose skin can be a common issue after significant or rapid weight loss, particularly depending on age, genetics, and how much weight has been lost. While exercise (especially strength training) can sometimes help improve muscle tone and appearance, loose skin is often unavoidable.

If someone has reached a weight they are happy with and is still losing weight while taking medication, it’s really important to speak with a healthcare provider. Any decision about adjusting or stopping medication should be an informed decision and made with a full understanding of the options and proper clinical oversight.

As for long-term maintenance, it’s important to understand that obesity is a chronic health condition, much like high blood pressure or type 2 diabetes. While some people can maintain their weight after stopping treatment, weight regain is very common once medication is discontinued. That’s why ongoing treatment and support are needed to help with sustainable weight management.

Focusing on long-term habits, setting small goals, staying active, and building healthy routines during treatment can support long-term goal management. There’s no one-size-fits-all solution, and it’s about finding the right approach that can be sustained over time.

Hi @TinyRebel These medications are not currently approved or available on the NHS for lipoedema.

Clinical research is required for any treatment in new population groups/specific condition segments to validate the safety and efficacy. If approved, then guidelines and safe practices would be updated for wider roll-out to specific condition populations.

Hi @SparklingBettie Thanks for your question. It's good that you're thinking ahead about your long-term plan.

There isn't one set way to come off treatment, and people respond differently. If someone has reached their goal weight, doctors may suggest slowly lowering the dose over time. It is important that any changes to a treatment plan are made with oversight from a healthcare professional. Always speak to a doctor or pharmacist if you have questions about stopping or changing any medication.

Research shows that people can gain back some or all of the weight after stopping their weight loss treatment plan. That's because the medicine supports changes that can be hard to keep up on your own. Focusing on long-term habits, setting small goals, staying active, and noticing how much better you feel can all help with motivation. Lifestyle, routines, and habits built during treatment will support long-term goal management.

Hi @Perimenopausalmanicmum Thank you for sharing your journey.

In general, clinical research indicates that GLP-1 receptor agonists aren't recommended for people with Addison's disease due to safety concerns. As these treatments are prescription-only medications, a full clinical review is needed to decide what is safe and appropriate. The best next step is to complete a consultation, and a healthcare professional can look at your overall health and support you in exploring safe options.

Hi @sharond101 This is a very individual decision and depends on many factors, including your health goals and how your body responds. It’s important to remember that obesity is a long-term health condition, so many people find that ongoing treatment helps maintain their progress.

When considering stopping, it’s best to do so under the guidance of your healthcare provider. They can help you adjust your approach to focus more on sustainable habits like balanced nutrition, regular physical activity, and stress management. Keeping these healthy routines in place can be essential to maintaining weight loss over the long term.

Hi @TreesOfGreen99 It is healthier and safer to aim for a steady rate of weight loss of around 1 kilogram (about 2 pounds) per week. Losing weight too quickly can increase the risk of side effects such as gallstones or result in excess loose skin. It’s important to make sure you’re eating enough, focusing on balanced meals high in protein and essential nutrients to avoid deficiencies.

If you or someone you know is experiencing rapid weight loss, it’s a good idea to speak with a healthcare provider. They can help review the treatment plan and offer support to keep weight loss safe and sustainable over the long term. Managing weight loss is a marathon, not a sprint -and ensuring your body stays nourished is a key part of that journey.

Hi @TiredyMcTired Thank you for your thoughtful questions.

Not everyone needs to increase their dose. The step-up dosing schedule is designed to help you find the lowest dose that works effectively for you while minimising side effects. Some people experience good results on the starting dose, while others may need to increase gradually if their weight loss plateaus and side effects remain manageable.

Regarding side effects, it’s common to experience mild symptoms such as nausea, vomiting, diarrhoea or constipation, especially early on. These often improve over time. More serious side effects like pancreatitis or gallbladder issues are rarer, but important to be aware of. There is currently no evidence that this class of medication increases the risk of thyroid cancer in humans. If you have concerns, it is important to discuss them with your healthcare provider.

For maintenance, ongoing support is often needed because obesity is a chronic condition. Access to medication after reaching a healthier weight depends on clinical guidelines and individual circumstances, which your provider can help navigate.

If you’re exploring whether this type of treatment might be suitable for you, the best place to start is by completing a consultation, which will be carefully reviewed by a healthcare professional.

Hi @vulvacious Nausea is one of the most common side effects. It often feels like a churning or unsettled sensation in the stomach and can be particularly noticeable in the early stages of treatment. This happens because the medication slows how quickly food leaves your stomach, which helps you feel fuller for longer. However, this can lead to nausea.

There are a few ways to help manage this. Drinking plenty of fluids like cold water or herbal teas (such as peppermint) can soothe the stomach. Getting regular fresh air may help settle the queasiness. Eating small, frequent meals rather than large ones can be easier on digestion, and reducing your intake of sugary or fatty foods can also make a difference. Some people find that avoiding strong-smelling foods when cooking or eating helps reduce symptoms, too.

If nausea continues or becomes difficult to manage, it’s a good idea to speak to a healthcare provider for tailored advice.

Hi @hannahp1209 That’s a really important question. These medications have come into the spotlight more recently for weight management, but the type of medication (GLP-1 receptor agonists) has been used for over 20 years to treat type 2 diabetes. So while using them specifically for weight loss is newer, there is a solid base of long-term data from diabetes care that helps inform our understanding of their safety.

Research is ongoing, and new information continues to emerge. Studies so far suggest these medicines may offer health benefits beyond weight loss, including improvements in blood pressure, cholesterol, and inflammation levels. Like with any medicine, there are potential risks, but the current evidence suggests that the benefits (especially in managing obesity, which carries serious health risks) can outweigh them for many people.

Hi @DinkyDaffodil Reaching your goal weight is a major achievement, but maintaining it can be challenging. One of the most important tips for staying on track long-term is to focus on building sustainable habits throughout your weight loss journey and not just after. That means paying attention to things like regular exercise, balanced meals that are high in protein, managing stress, staying hydrated and being mindful of emotional or stress eating.

Some people do stay on a lower dose like 2.5mg long-term if it helps manage their appetite and prevent weight regain. The goal is always to find the lowest effective dose that works, and for some that might be 2.5mg. Ongoing use should always be guided by a healthcare professional based on individual health and needs.

Weight management is a long-term process, especially since obesity is now recognised as a chronic health condition. For many, continued support can be necessary to keeping weight off in a safe and healthy way.

Hi @Fancyquickthinker While everyone’s response is different, studies show that weight loss with this class of medication typically includes a reduction in visceral fat, which may not always be visible on the outside but has a meaningful impact on metabolic health.

Hi @Hkakge Yes, the idea of ongoing or "maintenance" dosing is becoming more common in discussions around long-term weight management. That’s because obesity is now recognised as a chronic health condition, and just like other long-term conditions, it may require ongoing support to maintain results.

Hi @chickenpotnoodle Long-term weight management is such an important part of the journey.

Obesity is now recognised as a chronic condition, so it is becoming more widely accepted that some people may need ongoing support to maintain their progress, just like with other long-term health conditions. Once someone stops taking a weight loss treatment, continuing with healthy habits (like balanced eating and regular movement) becomes even more important. We focus on education and behaviour changes as part of the wider weight loss journey and not just while on a treatment plan.

If weight regain happens, it doesn’t mean someone has failed - it just means the condition needs further support. In many cases, treatment can still be effective again, but this would always depend on individual circumstances and a healthcare professional’s assessment.
