Thinking about starting Wegovy and bracing for a few rough days? You're in good company.
Most people taking Wegovy run into some side effects early on, and almost all of them hit the gut. But don’t worry, they tend to settle as your body adjusts to the medication.
Let's walk through ten common Wegovy side effects and how to manage them with food that actually helps.
1. Nausea
Nausea is the one that almost everyone mentions. It tends to creep in within days of a dose increase, then eases off on its own.
Here are a few habits that can take the edge off:
-
Eat smaller meals and slow right down
-
Sip water or suck on ice chips all day
-
Lean on ginger to calm your stomach
-
Dodge fried, oily, or spicy foods and strong smells
If the nausea drags on or wipes out your appetite, seek medical advice from your provider.
2. Diarrhoea
Loose stools come with the territory, so hydration matters most here. Sip water, broth, or cold-pressed juice whenever it strikes.
Caffeine revs up your gut, so put coffee and energy drinks on pause. Fibre-rich foods like bananas, oats, and brown rice digest slowly and help calm everything.
Dairy can be a culprit for some, even without a lactose problem. A short break from it might bring relief.
3. Vomiting
Already feeling queasy? That makes being sick more likely. Since food lingers in your stomach, vomiting shows up fairly often, though it usually clears within days.
The same nausea tactics carry over. Ginger helps, and smaller portions take the pressure off your stomach.
Toast and crackers are gentle choices, or you can skip solids for a day. Keep fluids going with ice chips or ice pops when water won't sit well.
4. Constipation
Slower digestion means things can grind to a halt. Fibre is what gets you back on track, around 25–30g a day from whole foods.
Make sure to work these into your meals:
-
Fresh fruit and vegetables
-
Whole grains like brown rice and whole wheat pasta
-
Nuts and seeds
Drink plenty of water and add a daily walk to get things moving. Hitting your fibre target gets tricky when hunger fades.
EXALT packs cold-pressed fibre into drinkable smoothies, so reaching that goal is easier.
5. Headaches
Headaches often crop up in the early weeks, and the usual culprit is mild dehydration. When you're eating and drinking less than your body wants, fluid levels dip, and your head feels it.
Skipping meals can drag your blood sugar down, too, which adds to the throbbing.
The solution is mostly about topping up what you've lost:
-
Drink water steadily through the day rather than gulping it all at once
-
Reach for rehydration sachets if the ache hangs on, since they replace lost salts
-
Take paracetamol for relief when you need it
-
Eat something light and regular to keep your blood sugar even
Most headaches fade once your fluids are back on track.
6. Abdominal Pain
Most belly pain on Wegovy is mild and rides along with another symptom, like bloating or constipation. It comes from food creeping slowly through your gut.
Sort out the underlying cause, and the pain often eases. Small bites and modest portions help too.
Now and then, the pain turns severe, which can point to pancreatitis. Get urgent in-person care for severe abdominal pain, pain that spreads to your back, or pain with fever or relentless vomiting.
7. Fatigue
Tiredness often follows from eating and drinking less than your body wants. There's simply less in the tank.
Regular nourishment throughout the day helps, and so does decent sleep. On the days a full meal feels like too much, liquid nutrition goes down easily. A protein-rich smoothie lifts your energy without any cooking involved.
8. Heartburn
With food and stomach acid sitting around longer, heartburn becomes more likely. It often flares in the days after you raise your dose.
Give these common triggers a wide berth:
-
Spicy and fried foods
-
Tomatoes and acidic foods
-
Coffee and fizzy drinks
Easing off these for a while calms your stomach. Eating earlier in the evening helps too, so acid isn't pooling while you lie down.
9. Dizziness
Eating less, skimping on fluids, or losing them through diarrhoea can leave you light-headed. Topping up food and water usually steadies things.
People on diabetes medication like insulin or metformin face a higher chance of low blood sugar. Look out for shaking, sweating, a racing heart, or sudden hunger.
Tell your provider about your medications before you begin. Get in touch if the dizziness won't pass.
10. Injection Site Reactions
Some people notice redness or itching at the injection site. A bit of care makes a difference.
-
Switch your injection spot each week so the skin heals
-
Clean the area beforehand to keep infection away
-
Dab on numbing cream before you inject
-
Use antihistamines for any rash or irritation afterwards
Most of these reactions are mild and calm down within a day or two. Rotating between your stomach, thigh, and upper arm gives each spot time to recover.
Less Common Side Effects to Watch Out For
Here are a few less common side effects that you should know about:
-
Raised heart rate
-
Elevated pancreatic enzymes
-
Delayed stomach emptying
-
Low blood sugar without diabetes
-
Raised bilirubin, seen as yellowing of the eyes or skin
Wegovy can also bring rarer gallbladder problems and allergic reactions, like swelling of the face.
Tell your provider if you have a family history of medullary thyroid cancer before using Wegovy. Speak to your healthcare provider immediately if any of these appear.
