Our pharmacists will recommend the most suitable treatment for you based on your BMI, other medicines you are already taking and any other health problems you may have.

Some of the most common side effects from weigh loss injections include nausea, vomiting, diarrhoea, constipation, stomach pain and fatigue.

These will usually go away on their own. If you feel sick, drinking lots of water and eating smaller meals and easy to digest foods will help. If you get a headache, drink water, rest and taking over-the-counter pain killers.

If you are taking weight loss pills, you may need to go to the toilet more often or have oily or fatty stools. Eating less fat can help with this.

You can find out more about possible side effects by reading the information leaflet carefully when you receive your medication. Please contact us for advice if you are worried about any side effects.

If you have a serious side effect, such as an allergic reaction, call 999 or ask someone to take you to A&E. 

To lose weight safely, the NHS recommends you should reduce the amount of calories you eat by 600 every day. This means men should limit their intake to no more than 1,900 calories and women to no more than 1,400. This will create a calorie deficit, which means you are eating less calories you burn.

You should also eat more fruit, vegetables, wholegrains and healthy fats (such as salmon or other oily fish). Try and include healthy proteins, such as chicken, lean beef, eggs or beans, with every meal as they will help you to stay fuller for longer. Limit sugary food and drinks, high fat or deep fried foods, as well as white bread and alcohol.

Exercise is also really important. Try and do around 150 minutes of moderate intensity exercise every week, such as power walking, swimming or cycling, and add in some higher intensity activities like running if you can. As well as helping you lose weight, exercise can help protect your bones and joints as you grow older and prevent conditions such as heart issues, stroke and diabetes.
