I’ve been practicing yoga for 4 years and continue to experience nausea and discomfort that lasts for minutes to hours after certain poses. There is no history of gastric problems and my doctor has found nothing that seems to suggest a hiatal hernia or other gastric anomaly. Shoulderstands, backbends, the fish, and camel are most problematic. Headstands and forward bends do not produce any of the symptoms.
I have an attentive teacher that makes sure that my breathing is proper and neck is protected, and has offered exercises to help strenthen the neck. any thoughts?
It sounds to me as though you have consulted a phsyician with some likely candidates for causing this problem. good that you have done that. Now we are left with 2 possibilities either the instruction is not clear or your body has some unique shape to its organ positions. If it is the latter than you might need more transit time between eating and these poses than others doing same poses. If it it the former then some posibilites that occur to me are to extend that is lengthen your neck in all these backbending poses and not compress the chin into jugular notch while doing shoudlerstand. The head in fish should not be dropped backwards but rather use muscles exerting effort to hold the head up so you are looking forward. let me know what you discover if these are helpful or not. if not then i have other thoughts to consider. namaste mukunda
