It is hard to answer your question without having more information on your case and the reasons you sought chiropractic care. Sometimes, after an adjustment you can feel a little achy or tight and if you had some interference in your nervous system (parasympathetic nervous system dominant) you can feel constipated or tired etc. So, when we apply a chiropractic adjustment, it can help with those types of issues so people could have better bowel movements or sometimes mild diarrhea because the sympathetic nervous system was stimulated.
Now, again it’s hard to know if that bout of diarrhea was due to the adjustments or if something else is going on. Nausea would usually not be a side effect of a regular chiropractic
adjustment. Did you have some gastro-intestinal manipulation done? That can sometimes happens then but rarely with a regular diversified adjustment. I would advise you to monitor your symptoms and call your health care provider and if it doesn’t get better or if you feel anything else, I would go get checked by your primary care provider to make sure the nausea and diarrhea are not due to any other underlying issue or viruses etc.
Hope this helps,
