Hello. : Hello. Because of the length of time for your vomiting and diarrhea, this needs to be medically worked up. If your feel dizzy or faint when you go from lying to sitting, or sitting to standing (or your pulse increases by 20 or more when going from lying to standing) that could mean that you have not kept up with fluid losses. In that situation, you may need to go to an er or acute care clinic for intravenous hydration. If you have blood with emesis or bowel movement, go to er. This can show up as vomit that looks like dark coffee grounds or as bowel movements that are black, tarry and malodorous.
