I’m not sure I’m a migraine sufferer, but I definitely do identify with “poop headaches”. I have understood them for about two years now.
One day I had this serious headache behind my left ear. I took an aspirin with a full glass of water (also works with Tylenol). Coincidently I had to poop. The headache went away within 30 minutes after pooping.
This would happen about once a month. One day I drank the usually large glass of water without an aspirin. Soon had to poop. After the poop the pain went away within 30 minutes. I was amazed.
From then on, when the pain behind the left ear starts…I drink one or two large glasses of water (no aspirin)…then, very soon after have to poop. Did poop…and the headache is gone within 30 minutes.
I don’t know what’s going on with my guts to cause this. I am not constipated, nor have diarrhea, etc. Normal stools. No nausea or stomach aches.
I am curious why this works.

    I also have this problem. My bowels move everyday and seem normal but not enough BM comes out. When my bowels get too full I get a migraine. I take a generic of Maxalt MLT and it works, however, if I don’t take something to make my bowels move I will get a migraine everyday until I do! It could be bacteria related.

    I have this problem too, but more than once a month. It occurs at least once a day. Taking magnesium daily has helped with the poop migraines, BUT I’m in the bathroom longer.

    Scientists who study this connection refer to the digestive system as the “gut brain”, “second brain”, or more formally as the enteric nervous system (ENS). The vagus nerve connects the brain stem directly to the ENS, enabling direct communication between the two. No other organ system has such a direct pipeline to the brain. Over 90% of the signals traveling along the vagus nerve are sent from the ENS to the brain. Additionally, the ENS is capable of regulating digestion independently of the brain. This was demonstrated by a study in which researchers severed the vagus nerve of rats only to find that their digestive tracts were still functioning 100%. No other organ system can operate independently of the central nervous system.

    I have no answers for you but I’ve heard that

    “Drinking 1-2 glasses warm water in the morning, 20 minutes before breakfast, flushes your system, stimulates your bowels to move, and hydrates you,”

    Any idea why the headache goes away after the poop?
    Is the brain saying you need to poop? Even when there is no urge.
    Or is the brain saying drink a lot of water in order to get the urge?
    Get things moving so to speak.
