Hi. Thanks for your query. Noted the history of your husband having a BM and fell down in the bathroom and had been unconscious to the extent that he did not remember what happened. He was sweaty and said had cramps and felt sick to his stomach. All these things indicate a few things: This could have been an attach of vaso-vagal where the vagus nerve gets over-active to cause such a problem. Another possibility is that he is having intestinal infection and electrolyte imbalance due to loss into third space also can cause the same problems. I would advise you the following: Keep a watch see if there are loose stools, fever, chills or so. If such symptoms develop, take hi to ER and get investigated and treated properly.
