Everything You Need To Know About Wegovy Headaches
Just like any other medication, headaches are one of the most frequently reported side effects for patients who have started their Wegovy Journey. According to the majority of the clinical trials, it is considered as a very common side effect of the medication. It typically occurs during the stage when you are gradually increasing your dosage after every 4 weeks. This usually happens because your body is slowly adjusting to the new dosage as the week goes by. There were roughly 14% of adults or 1 in every 7 adults who experienced mild to moderate headache during the medication. Headache while taking Wegovy is usually caused by dehydration. The main job of Wegovy is to slow down your digestion or simply make you feel fuller for a longer period of time. Because of this, there is a slow down in your food intake as well as in taking fluids in your body. Not having enough fluids in your body is one of the main reasons for experiencing headache due to Wegovy.
While headache is a very common side effect, there are people who can’t tolerate this side effect especially if they need to work outside. Here are some of the ways on how you can manage and prevent it:
- You can start by adding electrolytes in your plain water. This could be a liquid IV, Nuun, or by just adding a pinch of salt and lemon. It helps your cells retain the hydration in your body.
- Practice eating small amounts of protein-rich food even if you are not feeling hungry.
- Don’t ever skip a dose or do not try to double it up. Strictly follow your schedule.
- Monitor your caffeine intake especially when you usually take it in the morning.
If this could not be tolerated anymore with these precautions, consult with your doctor immediately and let him know your condition. Don’t wait until you feel the worst side of it.
Can Wegovy Actually Cause Headaches?
People who have started taking Wegovy reported that headache is one of the common side effects that they have experienced during the medication. While this is typically temporary, you should understand its data and the usual physiological triggers to help you manage it as your body adjusts.
- Headaches typically occur during the first 16 to 20 weeks of the medication. This is the phase where you are gradually increasing your dosage after every 4 weeks, so your body is also adjusting to the present medication at that time.
- Again, it occurs generally because of dehydration. As Wegovy slows down the food intake in your body, it also slows down the fluid intake. It is why you need to be intentional in keeping yourself hydrated.
- If you are also eating enough calories or skipping meals because you are not feeling hungry, it could also cause a headache which most of the time is called the hunger headache. Caffeine withdrawal could also be the reason.

Verified Before & After
Tip 1: Stay Hydrated
Hydration matters because dehydration is the ultimate trigger of headache. It is recommended to take at least 2 litres of water per day depending on your activity level too. It could also help adding electrolytes and drinking herbal tea. You can set an alarm to keep you reminded of drinking water during your Wegovy medication.
Tip 2: Set A Healthy Balanced Diet
Avoid eating highly processed food and instead, eat whole foods, complex carbohydrates, and ginger to avoid experiencing headache & nausea. Aside from the fluid, you should also be intentional in the food you take.
Tip 3: Consider Over-the‑Counter Solutions
If headache is no longer tolerable or you want to at least manage the pain, you can try taking over-the-counter medicine like paracetamol since it is typically safe. But make sure that you discuss this option with your doctor too before taking Wegovy. This could help you have your options on what you need to do if there are side effects that you can no longer tolerate like headache.
Tip 4: Talk to Your Provider About Your Dosage Adjustments
Record your side effects every week so you can have a reference on what are the side effects present during the medication. This could help you and your doctor assess whether you need to increase your dosage or lessen in order to prevent any side effects.
Tip 5: Lifestyle Modifications
Aside from the precautions like keeping yourself dehydrated and having a healthy balanced diet, you should also practice having a good regular sleep. It helps mitigate headaches.
Conclusion
Headaches are a very common side effect of Wegovy and it is usually temporary. You don’t have to worry because it’s all part of the process. If your headache can no longer be managed through the precautions mentioned above, make sure to discuss with your doctor immediately so he can assess what could possibly be the reason for it.
