What Is Wegovy?
Wegovy contains semaglutide, a medication that mimics the GLP-1 hormone. It works by:
- Reducing appetite
- Slowing stomach emptying
- Helping control calorie intake
This mechanism supports gradual, sustained weight loss under medical supervision.
Common Wegovy Side Effects
Most side effects are gastrointestinal and tend to occur during the early stages or after dose increases.
Typical Wegovy side effects include:
- Nausea
- Vomiting
- Diarrhoea
- Constipation
- Abdominal discomfort
- Headache
- Fatigue
These effects are usually mild to moderate and often improve over time.
Why Side Effects Occur
Wegovy changes how quickly food moves through the stomach and affects appetite signals. This adjustment can temporarily disrupt digestion, leading to nausea or bowel changes.
A gradual dose escalation plan is used to improve tolerance.
Less Common but Serious Side Effects
Although uncommon, certain symptoms require prompt medical attention.
Serious Wegovy side effects may include:
- Pancreatitis (severe abdominal pain, often radiating to the back)
- Gallbladder issues (pain in the upper abdomen, nausea)
- Severe dehydration from prolonged vomiting or diarrhoea
- Allergic reactions (swelling, rash, breathing difficulty)
- Changes in vision (particularly in patients with diabetes)
Stop the medication and seek medical advice if these occur.
How Long Do Side Effects Last?
| Phase | What to Expect |
| First 1–2 weeks | Nausea and appetite changes common |
| Dose increases | Temporary return of symptoms |
| After adjustment | Symptoms usually reduce |
Persistence beyond a few weeks should be reviewed by a healthcare professional.
Practical Tips to Manage Wegovy Side Effects
To improve tolerance and comfort:
- Eat smaller meals and avoid overeating
- Limit fatty or fried foods
- Stay well hydrated
- Eat slowly and stop when full
- Follow the prescribed dosing schedule exactly
These steps reduce strain on the digestive system.
Who Should Use Caution?
Consult a healthcare professional before starting Wegovy if you have:
- History of pancreatitis
- Gallbladder disease
- Severe gastrointestinal conditions
- Certain thyroid disorders
- Diabetes-related eye conditions
At Earlsdon Pharmacy, guidance is available to assess suitability and safe use.
When to Seek Medical Advice
Contact a healthcare provider if you experience:
- Persistent vomiting or inability to keep fluids down
- Severe or worsening abdominal pain
- Signs of dehydration
- Unusual or concerning symptoms
Early intervention prevents complications.
