Thanks for writing in.
From the information given about your husband, he is having vomiting
for over a week now.
I suppose its some kind of gastrointestinal system infection (bowel infection).
First you kkmust see that he doesnt get dehydrated. This itself can get life threatening.
Then please give hime plenty of fluids to take.
You must take him to ER if his situation is not improving, else it can get worse and dangerous .
Hope this helps.
