The SIBO summit is being replayed today and tomorrow and I've gone over Dr. Kharrazian's talk on the brain connection. We know that Hashimoto's affects smooth muscle and I think Dr. K has explained the reason how and it begins with the vagus nerve in the brain stem. Your bowels are composed of smooth muscle so if the vagus nerve isn't active, neither are your bowels. The neurons in your brain must work together (plasticity). In Parkinson's patients the neural disabilities are seen in their muscles. They stiffen, their handwriting becomes very small and the tremors are really the last sign. With low hemoglobin anemia, the brain does not get enough oxygen and therefore the vagus nerve is not going to be very active. The palate and throat muscles will tire. I'll assume this continues if you're thyroid function is still low.
He said that gargling very aggressively during the day may activate your vagus nerve.
If you have a sensitive gag reflex and feel nauseous for a while if you do gag, you really need to work on building the vagus nerve just like you would, a muscle. In fact he suggests causing the gag reflex purposely to make your eyes water. That is another part of the motor function delivered by vagus nuclei. Coffee enemas are also very effective.
Anemia and low ferritin are part of the process but if inflammation is behind this, taking iron infusions may even increase the inflammation. Another reason supplementing may not be effective. We have to get our vagus nerve activated.
You can still sign up to listen to all of these interviews through tomorrow while they are still free on Facebook SIBO SOS Virtual Summit 2017. If you have time it is very worthwhile.
