Summary:

• Drink 2-3 litres of water per day to stay hydrated, eat small bland meals, and if you are taking multiple medications, monitor your blood sugar.
• If you are experiencing a severe, persistent headache that comes with vomiting, blurry vision, or other symptoms that are concerning, seek your doctor’s help right away.

 

What Is Ozempic?

Ozempic contains an active ingredient called semaglutide, a GLP-1 receptor agonist. It mimics the natural hormones of our body, which helps slow down gastric emptying, improves insulin response, and reduces appetite. This drug is approved to treat type 2 diabetes patients and is famous for being used off-label in the UK for managing obesity or overweight individuals.

But like most medications, Ozempic comes with potential side effects. One of its mild and temporary side-effects is headache, together with nausea, dizziness, fatigue, and stomach upset

 

Why Headaches Occur?

Headaches can occur especially during the first few weeks of taking the treatment or when your dose has been adjusted. The reason is because your body is adjusting to the medication, and it makes you dehydrated as your appetite becomes low.

The good thing is that most cases resolve within 1 to 2 weeks, after their blood sugar levels and hydration start to stabilise.

 

Ozempic-Related Headache: Understanding Its Cause

When you start using Ozempic, headache is one of the temporary, mild side effects you are going to experience during the first few weeks of taking it. You might feel uncomfortable and worried if you’re not sure why it happens. Understanding the cause of headaches can help you manage them effectively.

 

Direct Pharmacologic Triggers

These headaches are the direct effects of the medications in your body, your lifestyle, as well as external factors.

Direct Pharmacological Triggers

• Slowing of the digestive System: It affects your body’s nutrient absorptions and your blood sugar levels.
• Appetite suppression: It influences the chemistry of your brain and its circulation.
• These changes may affect the work of your blood vessels and nerves, which lead you to experience temporary headaches.

 

Nausea & digestive issues

The medication causes nausea that can make the muscles of your head and neck tight, which may lead to headache.

These side effects usually go away after a few weeks getting your body adjusted to the medications.

 

Indirect Triggers

These are headaches that are caused by secondary effects, lifestyle, or changes in your metabolism because of taking Ozempic.

 

Dehydration

Your thirst and appetite can be reduced once you take Ozempic drugs. So you will often drink less water, which makes you dehydrated. It can cause:

• Mild, pounding headaches
• Fatigue
• Reduced concentration
• Mild dizziness

You may notice these more during hot weather, exercising, or if you are sweating a lot.

 

Verified Before & After

Verified Before & After

 

Hypoglycaemia

Although having a low blood sugar on Ozempic can be rare, it can increase the risks if you are taking other medications like insulin, sulfonylureas, and other medications that can lower blood sugar level. You may experience shakiness, sweating, irritability, and sudden hunger if you have low blood sugar headaches.

Decreased food intake and inconsistent meal

The drug can make you skip your meals or eat just a small portion because you don’t feel hungry. Because of this:

• It reduces the availability of glucose for your brain.
• It increases your chance to have headaches.
• It can make you feel irritable and tired.

You still need to eat nutrient-rich food on time even if you feel full.

 

Changes in sleep & Stress

Sometimes, people experience stress or anxiety when they start a new medication. Particularly when the treatment is delivered via injections. Tension headaches can be triggered by stress and your sleep can be deprived when you are nauseous or uncomfortable with the recent adjustments.

 

Caffeine reduction

Individuals who started using Ozempic can naturally reduce intake of their coffee for caffeinated beverages. Because of this, mild caffeine withdrawal headaches can be triggered.
