What Causes Migraines

Many people suffer from migraines and don’t understand why or what causes migraines. The real cause of migraines is still unknown, but several factors make your chances of getting migraines higher.

If you suffer from migraines, read the following article to determine what causes migraines in the human body and how to cope with them.

A migraine is the most common kind of headache, which can be debilitating. The symptoms associated with migraine include throbbing pain on one side of the head, nausea, vomiting and sensitivity to light and sound.

In this article, we will take a look at the causes of migraines and how to treat them and some lifestyle changes you can make to prevent migraine from occurring.

What Causes Migraines In The Human Body

What are migraines?


First, let’s review what migraines are. Many people think of it as a regular headache; however, that couldn’t be further from the truth.

While there are similarities between headaches and migraines, they are two entirely different conditions with different symptoms.

A migraine happens when your blood vessels dilate and expand beyond their normal size. When they begin to swell, they pressure your nerves which may result in extreme pain or sensitivity to light or sound.

It can also lead to a chemical imbalance that can cause nausea, vomiting and even loss of consciousness. What causes migraine is still unknown, but researchers have found some interesting reasons why some people get them more than others.

For example, women are three times more likely to experience migraines than men. People who suffer from depression or anxiety may also find themselves experiencing migraines more often than those who don’t suffer from these disorders.

Stress is one of the most common triggers for those who suffer from migraines, so if you feel like you have too much stress in your life, try finding ways to relax!

Another common trigger for migraines is dehydration, so make sure you stay hydrated by drinking plenty of water throughout the day!

If you think you might be suffering from an underlying medical condition like high blood pressure or hypothyroidism, talk to your doctor immediately because treating these could help relieve some of your symptoms.

What causes migraine

Everyone has different triggers for migraines, and no one knows exactly what causes migraines. It’s been proposed that migraine headaches result from the enlargement of small blood vessels in and around your brain.

Blood vessels surround your brain, and during a migraine, these blood vessels expand or become swollen as they attempt to release excess fluid into surrounding tissues to keep you from having a headache.

What causes migraines? No one knows for sure, but it could be various factors like genetics, environmental triggers (like diet or stress), hormonal changes that occur at certain points in women’s menstrual cycles, and food sensitivities.

If you have an acute migraine, drink lots of water and rest until it passes. Take a pain reliever, either ibuprofen or acetaminophen, and avoid taking anything else with caffeine. Over-the-counter pain relievers like Excedrin contain caffeine and should be avoided if possible.

If over-the-counter drugs aren’t effective enough, your doctor may also prescribe stronger medication to help with migraines. You can check out the causes of stomach pain here.

What are the most common triggers?

We’ve already covered some common migraine triggers in a previous section, but there are several other common culprits.

Some experts believe that low serotonin levels can trigger migraines, so if you notice that your headaches go away when you’re on a diet with plenty of carbohydrates, you may want to try limiting them and see if it helps.

Sulfites and tyramine (both natural preservatives) can also cause migraines. If avoiding these triggers doesn’t help, consider adding an over-the-counter anti-inflammatory drug like ibuprofen to your migraine treatment plan.

Though some people report feeling worse after taking these medications, these medications aren’t for everyone. You should consult your doctor before starting any new medication.

What can be done during an attack?

There are two different migraine attacks, and pain characteristics can distinguish them. Many people experience both auras and migraines with their headaches, but not all individuals do.

When a person is experiencing an aura, they will have visual disturbances. An aura usually lasts for about 20 minutes before it resolves itself.

On the other hand, a typical migraine is characterized by a severe throbbing headache that feels like pressure behind one’s eyes or at one’s temples.

Unfortunately, most sufferers of migraines find little relief from simple over-the-counter medications like Tylenol and Advil because these drugs don’t address what causes migraines in the first place. If you suffer from migraines, you may want to consider seeing your doctor discuss treatment options.

Your doctor may prescribe medication such as Imitrex, which is used to treat acute migraine attacks. Imitrex works by constricting blood vessels around your brain and decreasing inflammation around nerve endings to reduce pain.

It’s important to note that while Imitrex does work well for many patients, it isn’t right for everyone, and some patients may even experience side effects such as nausea or dizziness when taking it.

Suppose you suffer from chronic migraines (more than 15 days per month). Your doctor might recommend preventive medications such as Topamax or Zomig, which help reduce the frequency of attacks and severity when they occur.

Diet Changes

One of the most common causes of migraines is dehydration when we don’t drink enough water. Processed foods are also a leading culprit.

A diet high in sodium will make your blood pressure go up and then down again, which may trigger a migraine episode. Dehydration and sodium are common triggers because they affect hormones that can lead to headaches.

If you’re looking for ways to stop headaches at their source, start by limiting your intake of processed foods and salt to see if that alleviates your migraines.

It would be best if you also looked into getting more exercise every day. It improves overall health, but it can reduce your risk of chronic pain as well. And be sure always to stay hydrated!

Medication Options


If you find that your migraines are caused by stress, there’s a good chance that taking some form of medication will ease those symptoms. Some people even take certain medications to prevent or reduce migraines.

These medications fall into three main categories: abortive, preventive, and prophylactic (preventative) medications. Let’s talk about each one in turn.

Abortive Medications – if you have a migraine attack coming on, it can be incredibly helpful to know what kind of medication might help get rid of it.

These include pain relievers like ibuprofen and naproxen, and triptans, which work on serotonin levels in your brain and have been shown to relieve migraines very quickly when taken during an attack.

Other non-steroidal anti-inflammatory drugs (NSAIDs), including aspirin, may help alleviate pain but don’t work as quickly as triptans do.

Preventive Medications – these medications may not help get rid of migraine attacks once they start happening, but they can often stop them from starting at all.

They include beta-blockers and antidepressants. Beta-blockers work by blocking out adrenaline, which is known to trigger headaches. Antidepressants can also be used for prevention because they change serotonin levels in your brain, making it harder for migraines to occur.

Prophylactic Medications – while these medications aren’t guaranteed to prevent migraines entirely, they have been proven effective at helping reduce their frequency and severity.

These include calcium channel blockers such as verapamil or diltiazem; tricyclic antidepressants such as amitriptyline; anticonvulsants such as topiramate; and other agents that affect blood flow through arteries in your head like flunarizine.


Many migraineurs and non-migraineurs alike suffer from chronic headaches. The pain is often a result of poor diet, dehydration, stress, or lack of sleep.

Our bodies need at least eight hours of restful sleep each night to function well, but many people don’t get that much because they work long hours or have hectic lives.

A good night’s sleep is essential to our physical and mental health; it helps us fight off illnesses and reduces our overall stress levels.

You should also make sure you are eating right, drinking plenty of water every day, and taking care of yourself by getting regular exercise and spending time with friends and family.

If none of these things helps reduce your migraines, consider seeing a specialist for further treatment options such as Botox injections or surgery.
