Knowing what side effects are possible, how common they are, and when to seek help means you can approach your weight loss journey with greater confidence.

What Is Wegovy?

Wegovy (semaglutide 2.4mg) is a once-weekly injectable medication licensed in the UK for chronic weight management in adults. It belongs to a class of medicines known as GLP-1 receptor agonists, which work by mimicking a natural hormone that regulates appetite and food intake.

Wegovy is prescribed alongside a reduced-calorie diet and increased physical activity for adults with a BMI of 30 or above, or 27 or above with a weight-related health condition.

It is not a quick fix, but for many patients it can be a highly effective tool as part of a wider lifestyle programme.

Common Wegovy Side Effects

The most frequently reported Wegovy side effects relate to the digestive system. These tend to be most noticeable when starting treatment or when the dose is increased, and they often improve over time.

Common side effects may include:

  • Nausea
  • Vomiting
  • Diarrhoea
  • Constipation
  • Stomach pain or discomfort
  • Indigestion or heartburn
  • Bloating or wind
  • Reduced appetite
  • Belching

Most patients find these symptoms are mild to moderate and settle within the first few weeks as the body adjusts to the medication.

  • Changes in vision or signs of diabetic retinopathy worsening
  • Symptoms of gallbladder problems such as severe upper abdominal pain, fever or yellowing of the skin
  • Thoughts of self-harm or significant mood changes

If you are ever unsure, do not hesitate to contact a healthcare professional promptly.

Tips for Managing Common Side Effects

Many patients find that making small adjustments helps reduce the impact of Wegovy side effects, particularly in the early weeks of treatment.

▶ Managing Nausea
  • Eat smaller, more frequent meals rather than large portions
  • Avoid rich, fatty or highly spiced foods, especially when starting treatment
  • Stay upright for at least 30 minutes after eating
  • Ginger tea or ginger biscuits may help settle the stomach
  • Eat slowly and chew food thoroughly
▶ Managing Constipation
  • Increase your daily fluid intake, aiming for at least 6 to 8 glasses of water
  • Include more fibre-rich foods such as fruits, vegetables, wholegrains and pulses
  • Stay physically active where possible
  • Speak to your pharmacist if constipation persists, as a gentle laxative may help
▶ Managing Injection Site Reactions
  • Rotate injection sites regularly between the abdomen, thigh and upper arm
  • Allow the pen to reach room temperature before injecting
  • Do not inject into areas that are tender, bruised or scarred
  • Ask our team to review your injection technique if reactions continue

  • Have a personal or family history of medullary thyroid carcinoma
  • Have a condition called Multiple Endocrine Neoplasia syndrome type 2
  • Are pregnant or breastfeeding
  • Have a history of pancreatitis
  • Have severe gastrointestinal disease
  • Are under 18 years of age

FAQs About Wegovy Side Effects

How long do Wegovy side effects last?

For most patients, side effects are at their worst during the dose escalation phase. They typically improve within the first four to eight weeks as the body adjusts.

Does everyone experience nausea on Wegovy?

Not everyone will experience nausea, though it is the most commonly reported side effect. Eating smaller meals and avoiding fatty foods can help minimise it.

Can Wegovy cause hair loss?

Some patients notice temporary hair thinning during rapid weight loss. This is generally related to the calorie deficit rather than the medication itself and usually resolves over time.

Is it safe to take Wegovy long term?

Wegovy has been evaluated in clinical trials over several years. For most eligible patients, long term use is considered safe under medical supervision.

What should I do if side effects are affecting my daily life?

Contact your healthcare provider. There may be adjustments to your dose schedule or additional support available to help you manage.

Can I drink alcohol while taking Wegovy?

Alcohol is not directly contraindicated, but it can worsen nausea and contribute to low blood sugar. It is advisable to limit alcohol intake during treatment.
