Question: what does it mean when your nose bleeds and you feel dizzy?
Answer: Usually a nosebleed from both nostrils is due to a heavy flow from one nostril; the blood has just backed up and overflown into the other. If blood drips down the back of the throat into the stomach you may spit up or vomit blood. Excessive blood loss can cause a feeling of dizziness, light-headedness and fainting.
