Wegovy is a powerful prescription medication for weight loss. But like all medications, it can come with side effects. If you’re starting Wegovy or considering it, you probably have questions about what’s normal, what’s manageable, and what to watch out for.
This FAQ breaks it down.
What are the most common Wegovy side effects?
The most common side effects are related to digestion and usually occur during the first 8–12 weeks of treatment:
- Nausea
- Bloating
- Constipation
- Diarrhoea
- Loss of appetite
- Fatigue
- Burping or acid reflux
- Headache
These symptoms are often mild to moderate and typically improve as your body adjusts.
Why does Wegovy cause nausea and bloating?
Wegovy works by mimicking a hormone (GLP-1) that slows down digestion and reduces appetite. This can cause food to stay in the stomach longer, leading to nausea, bloating, and early fullness.
The nausea is usually worse during dose increases, especially when moving up to 0.5 mg or 1.0 mg.
How long do side effects last?
For most people, side effects peak during the first few weeks of each dose level and then improve.
- Nausea may last 2–5 days after a dose increase
- Bloating, reflux, and fatigue may persist longer
- Most people feel more settled by weeks 6–8
However, some people experience side effects throughout the full titration schedule. If symptoms are severe or persistent, speak with your doctor.
Are side effects worse at higher doses?
Yes, side effects are typically more noticeable as you move up in dose. The 1.7 mg and 2.4 mg levels are where most people experience the strongest reactions, especially if they increased too quickly.
Titrating slowly and following your provider’s plan can reduce these effects.
What helps reduce side effects?
Here are proven tips that help many people manage Wegovy side effects:
- Eat smaller meals
- Avoid greasy or high-fat foods
- Stay upright after eating
- Don’t drink large amounts of fluid with meals
- Add ginger or peppermint (capsules or tea) for nausea
- Avoid alcohol during the first few weeks
- Walk gently after meals
- Don’t skip doses as this can worsen symptoms when restarting
If nausea or fatigue becomes too much, your doctor may suggest pausing or stepping back to a lower dose temporarily.
Can Wegovy cause fatigue or low energy?
Yes, fatigue is a common side effect, especially early in treatment. It may be caused by:
- Reduced calorie intake
- Dehydration
- Changes in blood sugar
- Mild dehydration from GI symptoms
It often improves after the first few weeks. Stay hydrated, add electrolytes, and eat small nutrient-dense meals.
Does Wegovy cause hair loss?
Hair thinning can happen, but it’s rare. It’s more likely to occur after rapid weight loss, not directly from Wegovy itself. The body sometimes sheds hair during periods of stress or nutrient depletion.
Eating enough protein, staying hydrated, and avoiding extreme calorie restriction can help reduce risk.
Can I stop Wegovy if the side effects are too much?
Yes, but talk to your doctor first. In many cases, pausing or reducing the dose temporarily can help. Restarting at a lower dose after a break often improves tolerance.
Stopping cold can lead to weight regain, so plan any changes carefully.
When should I talk to a doctor?
You should contact your doctor if you experience:
- Persistent vomiting or dehydration
- Severe abdominal pain
- Signs of gallbladder problems (e.g. sharp upper belly pain)
- Vision changes
- Symptoms that don’t improve after several weeks
- Concerns about continuing treatment
Most side effects are manageable, but it’s always better to check than to guess.
Final thoughts
Wegovy side effects can be uncomfortable at first, but for many people, they’re short-lived. With the right plan and support, most patients get through the adjustment period and go on to lose significant weight.
Still unsure? Speak to a doctor about your symptoms, or start a consultation online to see if Wegovy is right for you.
