There may be ways to manage your medications and the foods you eat to help ease your胃肠道symptoms and even shorten your migraine attacks. Here are some answers to common questions about diarrhea and migraine.
1. Is Diarrhea Common With Migraine Attacks?
腹泻并不常见symptom of migraine说，但它肯定发生了Roderick Spears, MD, a neurologist andheadache specialistat Penn Medicine in Philadelphia. “A smaller percentage of people will say they have diarrhea as asymptom of migraine与呕吐相比，“他说。
与腹泻不同，恶心和呕吐是国际头痛社会分类中列出的症状ICHD-3对于偏头痛。
Diarrhea can occur as a symptom of any type of migraine; it’s not related to one specific type, says Dr. Spears.
2.什么导致腹泻和头痛？
“我们认为腹泻和头痛之间存在联系血清素being the common denominator,” says Spears.血清素is a majorneurotransmitterthat helps regulate mood, but there are also a lot of serotonin receptors in the gut, he explains.
“In the majority ofpeople with migraine，肠道实际上会在攻击期间慢下来，而不是向前移动任何东西。在最坏的情况下，事情朝着相反的方向，人们体验呕吐，但为了较小的人，偏头痛实际上会加速肠道，而且他们发展腹泻，“矛。
3. Why Do Migraine Attacks Cause Vomiting and Diarrhea?
“Sometimes如果偏头痛没有停止，恶心会变成呕吐，“皮斯说。但他说，为什么呕吐或腹泻可以是偏头痛的一部分并不完全清晰。
“We know that vomiting will decrease intracranial [within the skull] pressure. There are some migraine patients, especially younger people, who tell me that if they呕吐during a migraine attack, it will abort the attack,” says Spears.
4. Can Digestive Issues Cause Migraine?
It hasn’t been proven that肠易激综合征（IBS）causes migraine or vice versa, says Spears, but “there is a correlation between the two conditions. If you have migraine, it seems you’re more likely to have IBS, and if you have IBS, you’re more likely to have migraine,” he says.
一种study published in the波兰神经病学和神经外科杂志发现23％以53％的IBS经历频繁的头痛，10％至20％的人口都有偏头痛和IBS。
一种IBS的诊断矛数目说，在偏头痛袭击中，不同于胃肠道（GI）症状不同。“当一个人有IBS时，他们有腹泻，constipation, or abdominal腹胀going on most of the time, and they can cycle between those different phases,” says Spears.
即使您在偏头痛中遇到这些类型的GI症状，他也不会一直在出现，他解释道。“即使在chronic migraine, you wouldn’t have a lot of patients in that category,” he says.
Chronic migraine is when a person experiences 15 or more days per month of headache with migrainous features for at least three months, according to theMigraine Research Foundation。eagodic偏头痛是当一个人每月较少的人数少于15个。

即使在腹泻的情况是脸上一个征兆ting from an underlying illness or infection, it may actually be the dehydration that triggers the headache, says Spears.

There are potential side effects for some acute medications as well. Some over-the-counter and prescription drugs, such asExcedrin偏头痛orFioricet, contain caffeine, which may contribute to diarrhea.
