Dealing with stomach acid reflux can sometimes be a headache, with advice often including lying on one side, not lying down after eating, changing diet, chewing slower or quitting smoking.
And while there are pills to take against reflux, it turns out they too could be a headache - a literal one - as a team of US scientists believes the medications could be causing migraines.
"People who take acid-reducing drugs may have a higher risk of migraine and other severe headache than people who do not take these medications," they found, after examining data on almost 12,000 patients in work published by the American Academy of Neurology.
The teams said their work did not "prove" the drugs cause migraines, but that there is an "association" that warrants "further investigation" and that people using the medications should see a doctor about continuing if they experience headaches.
The team said they did not examine the impact of over-the-counter treatments for acid reflux.
"These drugs are often considered to be overprescribed, and new research has shown other risks tied to long-term use of proton pump inhibitors, such as an increased risk of dementia," said Margaret Slavin of the University of Maryland in College Park.
