Weight Loss Medication

It’s been revealed that obesity is the second biggest preventable cause of cancer after smoking (WHO, 2022), and yet 63.8% of UK adults were overweight or obese in 2021 to 2022 (GOV.UK), making us the most obese nation in Western Europe (BBC Food, 2021). Whether it’s due to a rise in processed food (Etilé & Oberlander, 2019), a culture that does little to promote being active (Dhuli et al, 2022), or a lack of education (Cancer Research UK, 2022), it seems the UK as a whole need to try and live a healthier life.

If you want to lose body weight and achieve a healthy weight but diet and exercise alone haven’t worked, then we offer effective weight management treatments to assist you in achieving and maintaining a healthy body.

Obesity is a health condition that relates to an individual's body weight and BMI. You'll find answers to common questions that our team get asked about obesity below.

What is obesity?

The World Health Organisation (2024) define obesity someone with an excessive or abnormal accumulation of fat, within their body weight composition, that presents a risk to health. Obesity has been linked to lower energy levels and fatigue (Frank et al, 2022).

When are you classed a clinically obese?

You are classed as obese if your BMI (body mass index) is between the range of 30-39.9. A BMI of 40 or more is considered severely obese (NICE, 2023).

Can you be overweight but not obese?

Yes, it's possible to be overweight but not obese. You would be classed as clinically overweight if your BMI is in the range between 25 and 30 and classed as obese if your BMI is above 30 (The House of Commons Library, 2023).

How prevalent is obesity in the UK?

According to the NHS (2023), it is estimated that 1 in 4 adults and 1 in 5 children aged 10-11 are living with obesity in the UK.

What are the health risks of obesity?

Obesity can cause further health problems including type 2 diabetes, high cholesterol, sleep apnea, heart disease, high blood pressure and more (Mayo Clinic, 2023).

Does obesity affect fat cell production?

Yes, body fat cells are created at a faster rate in people who suffer from obesity (approximately twice as many new fat cells annually compared to a leaner individual) and similarly, an obese person's existing fat cells will die at a faster rate than someone who is lean (Medical News Today, 2022).

How can obesity be treated?

The best and most sustainable way to treat obesity and avoid weight regain is a weight loss journey that includes a lifestyle change including regular exercise and a healthy, reduced-calorie intake diet (NHS Inform, 2023). Additionally, regular physical activity and a healthy diet can improve how effective weight loss medications such as semaglutide, liraglutide and terzepatide are in treating obesity (Grave, R.; 2024).

For those who are dangerously obese, bariatric surgery (or weight loss surgery) such as a gastric band is also an option but it comes with risks (Bupa UK, 2021), scarring and a hefty price tag (NHS, 2024), so it should be considered a last resort, rather than a quick fix to achieve weight loss goals.

Weight Loss Experiences

Every individual's weight loss journey is unique to them and they will all have different experiences. Take a look at some independent experiences of people's weight loss journeys below that include natural weight loss treatments such as increased exercise and healthy dietary choices:

What are the benefits of weight loss?

Reduce the Risk of Type 2 Diabetes, Cancer and Heart Problems

Losing weight and maintaining a healthy BMI can ease your breathing, improve your confidence and reduce your risk of type 2 diabetes, cancer and heart problems (Diabetes UK, 2023). It can also lead to sagging skin and gallstones though so losing weight at a safe rate is better than aiming for immediate results (Everyday Health, 2018). There has also been a link between weight loss and depression, which could be due to overweight people using binge-eating to mask other issues, or tying weight loss to the key to happiness and therefore feeling unfulfilled when they achieve or struggle to achieve it (Healthline, 2021). Commit to working through any emotional or psychological issues at the same time as trying to lose the excess weight.

Always consult with your doctor or health care provider for advice on the most appropriate course of weight loss treatment to aid your personal weight loss journey, to ensure that you lose weight in an appropriate, safe and sustainable way to suit your individual needs and continue to maintain a healthy weight.

Gaining extra weight can occur from an individual's diet and lifestyle (NHS, 2023) including:

  • Eating large amounts of processed or fast food
  • Eating out a lot
  • Comfort eating - due to stress, emotional factors and/or poor sleep (NICHD, 2021)
  • Drinking too much alcohol or sugary drinks

Mendis & Wiggins (2023) also mention other contributing lifestyle factors such as:

  • Not exercising enough
  • Medical conditions that make you less mobile
  • Side-effect of a medication that you're taking
  • Your age
  • Menopause
  • Genetics
  • Lack of sleep
  • Stress and lifestyle factors
  • Appropriate weight gain

Can weight loss improve high blood pressure?

Yes. Healthy forms of weight loss management such as exercise and a well-balanced diet have proven effective in improving high blood pressure in overweight individuals (Bacon et al, 2004).

Can weight loss cause hair loss?

Stress on the body and/or nutrient deficiencies can potentially cause hair loss after weight loss achieved through weight loss surgery (bariatric surgery) or restrictive dieting, although this type of hair loss is typically only a temporary condition, medically called ‘telogen effluvium’ (Medical News Today, 2021).

Weight Loss Medication FAQs

Below you'll find answers to common question our team get asked about relating to prescription weight loss medication.

Before considering weight loss treatments such as prescription medications for weight loss, one of the most important things when trying to lose weight is getting your diet under control whilst also increasing physical activity (BBC Good Food, 2014). Aim to eat plenty of fruit and vegetables every day, eat protein-rich foods and opt for fibre-rich carbohydrates for long term sustainable weight loss (Livestrong.com, 2009). Don’t deny yourself all treats but do snack a little wiser with a reduced calorie diet; reach for foods that you can have a lot of, without a lot of calories such as air-popped popcorn or rice cakes (SheFinds, 2023).

Try to create a weight loss plan that’s achievable and avoid having sugary, fatty foods (foods high in saturated dietary fat) in your house so that it’s easier to resist temptation. Choose water above other sugary drinks and/or alcohol, or sugar-free natural fruit juices if you fancy something different (Healthline, 2023).

Losing weight is also about consistent exercise and physical activity (Cox, C.; 2017), so start by introducing this into your weight loss routine too. Even just 150 minutes of exercise a week can make a big difference (NHS, 2023), so start small to avoid feeling overwhelmed and falling off the wagon.

Google Web Story: How To Lose Weight

UK Meds have created a Google Web Story guide to explain how to lose weight, covering medical and lifestyle-focused weight loss treatments. You can view it below:

Weight Loss Tablets

If your BMI is greater than 30 and you haven't been able to lose weight through natural weight loss treatments such as diet and exercise alone, your doctor / health care provider may suggest weight loss tablets (also referred to commonly as ‘diet pills’) as an anti obesity medication to aid your journey if they deem it appropriate for your individual needs (Mayo Clinic, 2022). UK Meds offer the weight loss tablets Xenical, Orlistat and Alli.

For more information on any of the weight loss tablets, please refer to the patient information provided with the medication:

How should you use a weight loss pill?

You should only use weight loss pills to achieve body weight reduction as instructed by your doctor or health care provider, to ensure that any diet pill weight management medication is being taken in the safest way to suit your individual requirements. Weight loss supplements should not be a substitute for healthy eating habits.

Weight Loss Injections

If your BMI is over 30 and you’re considered obese, then you can aid your weight loss mission with help from GLP 1 Agonist weight loss injections at UK Meds, if your doctor recommends them as a suitable course of weight loss treatment for you to achieve your weight loss goal (British Heart Foundation, 2024). Offering effective results as an appetite suppressant, we stock a range of prescription GLP 1 Receptor Agonist weight loss injections that can aid diet and exercise in your weight loss journey, provided they have been recommended by your doctor. Weight loss injections offered by UK Meds include: Mounjaro (tirzepatide) weight loss pen, Wegovy (semaglutide) weight loss pen and Saxenda (liraglutide) weight loss pen.

For more information on any of the medical weight loss injections, please refer to the patient information provided with the medication:

How should you use weight loss injections?

You should only use and dose a weight loss injection as instructed by your doctor or health care provider to ensure it is being taken in the safest way to suit your individual requirements as a weight loss aid. Weight loss injections are not a substitute for increased physical activity and regular exercise (which itself is a very effective natural way to promote fat burning / fat metabolism and overall fat loss) and a sticking to a healthy diet and consuming fewer calories.
