Aside from good and bad bacteria, some essential hormones and neurotransmitters are created in the gut and have a significant effect on our brains. Some studies have also shown that a disruption to the normal, healthy balance of bacteria in the microbiome can cause the immune system to overreact and contribute to inflammation of the GI tract, which in turn can lead to the development of diseases that occur not only throughout your body, but also in your brain.
Another study backs his theory and Dr. Wright’s comments up. This study was carried out on 64 patients all assessed using the MIDAS (Migraine Disability Assessment) test and concluded that “H. pylori eradication may indeed have a beneficial role on migraine headache.” Some medical experts remain sceptical and believe that this may be a coincidence or a temporary lull. The jury is mostly out on this one at the moment.
This may not be a cure and everyone who suffers from migraine knows that there is nothing that works for everyone, but it’s another option to explore. So take care of your second brain and it might help you to take care of your first brain!
