Neurologist says vomiting is not migraine relief

A headache specialist is pushing back on a recent study that linked vomiting during migraine attacks with faster pain relief. Dr. Egilius Spierings says the findings are being misread and warns patients not to treat vomiting as a remedy.

Why it matters: - Migraine patients may mistake vomiting for a sign that the attack is improving, but Dr. Egilius Spierings says that interpretation could lead to harmful self-treatment. - Vomiting can worsen dehydration, reduce medicine absorption and add to migraine-related disability. - The warning matters because research findings can be misunderstood as treatment advice.

What happened: - Dr. Egilius Spierings, a neurologist and headache specialist, responded to a recent study that linked vomiting during migraine attacks to faster pain relief. - The study found that some patients reported improvement after vomiting. - Dr. Spierings said that sequence does not prove vomiting caused the headache to subside. - The study was conducted at the Headache Center of the University Hospital of the University of Florence.

The details: - Dr. Spierings said vomiting is a sign of illness, not a treatment. - He said migraine attacks move through phases, and pain may already be easing when vomiting occurs. - He said vomiting can make patients feel worse by causing dehydration. - He said vomiting can interfere with medication absorption. - He said nausea and vomiting are often overlooked as major contributors to migraine disability. - He said many migraine headaches do not fully limit function until nausea begins. - He said the straining that comes with vomiting can make headaches worse. - He said temporary relief can come from reduced stomach distension, but that relief does not last. - He said stomach complaints during migraine are generally tied to slowed gastric emptying caused by intense pain and sympathetic nervous system activation. - He said prescribing anti-nausea drugs such as Zofran® can further slow stomach emptying and can also hinder absorption of migraine medicine. - He said vomiting can sometimes have a different effect in very young children, where it may shorten the episode and ease stomach distress. - He said adults should avoid vomiting whenever possible. - He said the headache center in Florence is one of the oldest in the world and was founded in the early 1950s by Professor Federigo Sicuteri. - He said 77% of that center's patients experienced vomiting with migraine attacks, which he sees as evidence of poor treatment.

Between the lines: - Dr. Spierings is drawing a hard line between a research observation and a care recommendation. - His criticism suggests the bigger issue is not the study itself, but how easily patients and clinicians may overread it. - He is also challenging the idea that controlling nausea should come before treating the headache itself.

What's next: - Dr. Spierings is available for interviews. - He is urging migraine patients to seek therapies that stop the headache rather than tolerate symptoms that make them feel worse. - More information is available here.

The bottom line: - Vomiting may happen during migraine attacks, but Dr. Spierings says it should be seen as a warning sign, not relief.
