About an hour after we ate my wife started vomiting excessively followed by diarrhea, she also has fine red spots on her face. her balance is not great either. she has stomach cramps. what can it be and what should i do?

Dr. or ER can check: Normal healthy young adults can get the stomach flu or food poisoning symptoms from time to time. A patient will usually vomit until her stomach is all empty, which is why it is helpful to not eat or drink anything for a few hours afterwards. That said, a person who is not balancing well likely needs examination in the ER to see if IV rehydration is needed, and diagnose a possible cause.
