Do you suffer from both acid reflux and chronic headaches? If so, you may be surprised to learn that the two conditions are closely linked. We review the research on the connection below.
What Is Acid Reflux?
Acid reflux refers to when the contents of a person’s stomach flow back into their esophagus. This can lead to symptoms such as:
- Chest pain
- Difficulty swallowing
- Chronic cough
If these symptoms are chronic or severe, you may be diagnosed with gastroesophageal reflux disease (GERD).
Why the Link?
It’s unclear why there’s a link between acid reflux and headaches; experts aren’t certain whether acid reflux causes headaches, headaches cause acid reflux or both tend to occur together.
One theory about how their linked has to do with the gut-brain axis, which involves the autonomic nervous system (ANS). The ANS’s job is to deal with involuntary processes like respiration and digestion. It is made up of three main components:
- The sympathetic nervous system (SNS) is in charge of your body’s “fight or flight” response. It is the body’s automatic reaction to threats.
- The parasympathetic nervous system (PNS) controls a person’s “rest and digest” response. It helps the body relax once a threat has passed.
- The enteric nervous system (ENS) regulates certain digestive functions, including muscle contractions and secretions.
What Does the Research Show?
Several studies discuss the link between acid reflux and headaches:
- A 2015 study found that GERD is associated with impaired PNS function, meaning the link between acid reflux and headaches could result from a malfunctioning ANS.
- A 2017 study noted there is a link between ANS dysfunction, headaches and gastrointestinal (GI) disorders.
- Research from 2020 found that issues with glutamate levels can lead to GERD or migraine headaches.
Strategies for Managing Acid Reflux
You can manage acid reflux with a variety of strategies, including:
- Eating smaller, more regular meals.
- Not eating within three hours of sleeping.
- Avoiding triggering foods.
- Elevating the head and chest when sleeping.
- Taking antacids, H2 blockers or PPIs.
- Quitting smoking.
- Going to Piranha Fitness Studio to lose weight.
- Undergoing surgery.
