My husband began feeling dizzy and hot. then some stomach aches and nausea. the dizziness was the worst and within an hour started vomiting only ones. what can these symptoms be?

Doctor can examine: One's primary care doctor can evaluate where the nausea and vomiting might be coming from. Many conditions can cause nausea and vomiting. A person can write down his symptoms, from the beginning, to show his doctor. Include details on what actually happens, when it happens, what improves symptoms, what worsens symptoms, any food relationships, any sick contacts, any travel or animal contacts, etc.
