Migraine (Headache and Nausea): Meaning, Causes & Treatments

What is Migraine?

Headaches and nausea often occur simultaneously, and while experts are uncertain about the specific reasons for their correlation in certain individuals, factors such as dehydration, migraines, or other health conditions can contribute to experiencing both symptoms concurrently.

Migraine headaches are frequently accompanied by nausea and vomiting, constituting a common occurrence in migraine sufferers. Research suggests that approximately 8 out of 10 individuals experiencing migraines also report symptoms of nausea. Studies indicate that women and individuals prone to motion sickness are particularly susceptible to experiencing nausea alongside migraines, with hormonal fluctuations possibly playing a role in the heightened prevalence among women.

Furthermore, migraines can manifest during pregnancy, often characterized by unilateral head pain and accompanying nausea. Interestingly, some pregnant individuals may notice a decrease in migraine frequency, while others may experience an increase in headache occurrences.

Cyclic vomiting syndrome (CVS), although distinct from migraines, shares a connection with migraine headaches. Predominantly affecting children, CVS episodes typically diminish as individuals reach adolescence. However, some individuals with CVS may transition into experiencing migraines in adulthood. Risk factors for adult-onset CVS include a history of migraines, prolonged marijuana usage, or a predisposition to motion sickness. Triggers for CVS episodes range from environmental factors such as hot weather and stress to sinus or respiratory infections.

The hallmark symptoms of CVS include sudden and intense episodes of nausea and vomiting, lasting from hours to days, with frequent bouts of vomiting during an episode. Between episodes, individuals may remain asymptomatic, leading to potential misdiagnosis by healthcare professionals who may mistake CVS for food poisoning or viral gastroenteritis.

Common Lifestyle Factors Contributing to Headache and Nausea

Your lifestyle plays a significant role in your overall health, potentially increasing the likelihood of experiencing headaches and nausea. Additionally, poorly managed health conditions can exacerbate these symptoms. Here are several examples:

Alcohol: Excessive consumption can result in waking up with intense headaches, nausea, vomiting, or abdominal discomfort. Other accompanying symptoms may include dizziness, extreme thirst, and heightened sensitivity to light and sound. Withdrawal from alcohol can also trigger headaches, nausea, and vomiting.

Caffeine: Whether due to skipping your morning coffee or attempting to reduce intake, caffeine withdrawal can manifest with headaches, nausea, fatigue, and difficulty concentrating.

Nicotine: Overindulgence in nicotine can lead to headaches and nausea, potentially accompanied by vomiting, increased heart rate, chest tightness, and respiratory difficulties.

Food Poisoning: Consuming contaminated food may result in headaches and nausea due to the presence of harmful pathogens. Prolonged vomiting from food poisoning can lead to dehydration, which can further exacerbate headaches.

Additional Factors Associated with Headache and Nausea

Should you experience headaches and nausea, it’s advisable to consult your physician and describe your symptoms along with any potential triggers. They will assist in identifying the underlying cause and recommend appropriate treatment.

Several common factors that may contribute to headache and nausea include:

1. Respiratory illnesses such as colds, flu, or stomach infections. These conditions often manifest with accompanying symptoms like a runny nose, diarrhea, chills, body aches, and fever, distinguishing them from migraines.

2. COVID-19 infection, characterized by symptoms like headache, nausea, vomiting, fever, coughing, and breathing difficulties, akin to other coronaviruses like SARS and MERS.

3. Fluctuations in blood sugar levels, leading to symptoms like nausea, headache, faintness, sweating, confusion, or in the case of high blood sugar, diabetic ketoacidosis.

4. Withdrawal from certain medications, particularly antidepressants like Lexapro, Prozac, and Zoloft, which can result in headaches and nausea.

5. Hormonal changes associated with PMS and menstrual cycles, often causing throbbing headaches, nausea, and light sensitivity before or during menstruation.

6. Preeclampsia, a condition characterized by high blood pressure during pregnancy, presenting symptoms like severe headaches, vision changes, abdominal pain, nausea, vomiting, decreased urine output, and in severe cases, HELLP syndrome.

7. Food poisoning from contaminated food, leading to headaches and nausea, with dehydration from vomiting exacerbating the headache.

8. Hypertensive crises or malignant hypertension, marked by severe headaches, nausea, and vomiting due to extremely high blood pressure.

9. Altitude sickness, also known as mountain sickness, occurring at high elevations and manifesting symptoms like headache and nausea.

10. Glaucoma, where increased pressure within the eyes can cause headaches alongside nausea and vomiting.

Uncommon Origins of Headaches and Nausea

Some infrequent causes to consider are:

1. Inner ear infection
2. Carbon monoxide poisoning
3. West Nile virus
4. Toxic shock syndrome
5. Dengue fever
6. Black widow bite
7. Cluster headaches
8. Brain bleeding
9. Brain injury
10. Brain tumor
11. Brain infection
12. Acoustic neuroma (a tumor affecting nerves linking the inner ear and the brain)
13. Malaria and yellow fever
14. Hepatitis A
15. Fifth disease
16. Kidney disease

Approaches for Alleviating Headaches and Nausea

Several strategies that may provide relief include:

1. Manage stress levels, as stress commonly triggers nauseating headaches. Implementing stress reduction techniques could potentially decrease the severity and frequency of your attacks.
2. Cease smoking.
3. Maintain a food diary to pinpoint potential headache triggers, such as chocolate and alcohol.
4. Ensure adequate sleep and rest.
5. Adhere to prescribed medications. Your healthcare provider may recommend drugs for headache prevention, particularly if diagnosed with migraines. Medications may also alleviate symptoms or halt headaches once they commence. Additionally, anti-nausea medications are available in various forms, such as pills, nasal sprays, suppositories, syrups, and injections. Considering their potential side effects, collaborate with your physician to determine the most suitable option.
6. Explore complementary therapies. Evidence suggests that biofeedback and acupuncture might alleviate migraines and other types of headaches, along with associated symptoms like nausea.
