Thinking of Switching to Wegovy?
See our guide below to make sure you've got all the answers you need to make the right decision for you.
How to Manage Common Side Effects of Wegovy
1. Changes to your sense of taste
A very small amount of people have reported that some foods taste slightly different than they used to. We do not know why this happens and more studies are ongoing.
How to manage it:
Some people have found that trying new foods or food with strong flavours can help. Though if you are concerned about this please contact us directly.
2. Diarrhoea, acid reflux and heartburn
As the medication works on your gut side effects that relate to the stomach are to be expected. These are generally mild and should go away as your body gets used to the medication.
How to manage it:
Eat smaller meals and avoid anything spicy or strongly flavoured.
3. Burping and gas or flatulence
Semaglutide slows down your gut so the gas we normally produce may hang around for longer creating more issues as it comes out.
How to manage it:
Thankfully these side effects are mild and return to normal as your body adapts to the new medication. If these are especially problematic we have a range of treatments that we can recommend to help you.
4. Nausea and vomiting
Unfortunately, this is the most common side effect of this medication. Sometimes you may vomit and other times you may just have a feeling of wanting to be sick. These effects do pass as you become accustomed to the medication. Equally the slow dose increase helps to reduce the chance of these symptoms from occurring.
How to manage it:
For most people, there are some simple changes and self-care that can help such as:
- Taking regular sips of a cold drink
- Drinking ginger or peppermint tea
- Eating foods containing ginger - such as ginger biscuits
- Eating smaller, more frequent meals
If the sickness or nausea is becoming unbearable please contact us as we have a range of treatments that we can provide for you to alleviate these unpleasant effects.

5. Dizziness or lightheadedness
A few patients have reported that they’ve experienced this early in their weight loss journey. It can often be made worse if you become dehydrated.
How to manage it:
Lie down until the dizziness passes, then slowly get up, moving carefully. Ensure that you avoid driving or operating machinery if you feel like this.
6. Fatigue
Feelings of tiredness or fatigue are usually a result of other effects of the medications such as reduced energy intake or vomiting and dehydration.
How to manage it:
Resting and taking time to adjust to the new changes in your lifestyle can help. It is always good advice to stay hydrated and not exert yourself too much.
Wegovy Weight Loss Injections
Wegovy is a specially formulated medication that’s clinically proven to aid weight loss. Taken as a weekly injection, it could help to control your appetite and prevent you eating more than you need to.
7. Headaches
These are usually caused by dehydration and they often pass quickly.
If the headaches persist please contact our medical team for more advice.
How to manage it:
Rest and try not to over-exert yourself. Maintain a good fluid intake. You can take paracetamol as required.
8. Abdominal pain or constipation
There can be many reasons for feeling like this, especially as you go through changes in your diet, and while your body adjusts to Wegovy. These are usually short-lived and resolve quickly.
However, if these are severe or do not go away they could be the signs of something more serious and you must contact your doctor or call 999 immediately.
How to manage it:
Small meals can help as can eating a bland diet. We can also recommend some simple over-the-counter treatments that can be taken to help.
How to reduce the chance of adverse reactions
Most of the side effects we’ve talked about are minor and do pass as your body gets used to taking Wegovy, and the majority of people can take this medication without issue.
To reduce any side effects to a minimum, the titration plan takes you from a low dose to a maintenance dose very gradually.
