My husband and I had dinner last night and he felt like it was very heavy for his stomach, he was burping and couldn't digest the food very well, we went to bed and at 3AM he got up to go to the restroom and passed out, he blacked out and felt on the floor. I called 911 and the paramedics said he had an indigestion and said he would be fine. Right now he has a headache and has been vomiting all night…is this a serious condition or he is just dehydrated and will get back to normal in a day?
