Exercise-induced nausea
{{Short description|Feeling of sickness after exercising}}
Exercise-induced nausea is a feeling of sickness or vomiting which can occur shortly after exercise has stopped as well as during exercise itself. It may be a symptom of either over-exertion during exercise, or from too abruptly ending an exercise session. People engaged in high-intensity exercise such as aerobics and bicycling have reported experiencing exercise-induced nausea.
Cause
A study of 20 volunteers conducted at Nagoya University in Japan associated a higher degree of exercise-induced nausea after eating.{{cite journal|last=Kondo|first=T.|author2=Nakae Y|author3=Mitsui T|author4=Kagaya M|author5=Matsutani Y|author6=Horibe H|title=Exercise-induced nausea is exaggerated by eating|journal=Appetite|date=Apr 2001|volume=36|issue=2|pages=119–25|pmid=11237347|doi=10.1006/appe.2000.0391|s2cid=29341304}}

Another possible cause of exercise induced nausea is overhydration. Drinking too much water before, during, or after extreme exercise (such as a marathon) can cause nausea, diarrhea, confusion, and muscle tremors.{{cite web|last=Rosner|first=Mitchell H.|author2=Tamara Hew-Butler|title=Exercise-associated hyponatremia|website=UpToDate |publisher=Wolters Kluwer|year=2010|url=http://www.uptodate.com/contents/exercise-associated-hyponatremia|accessdate=3 April 2013|ref=hyponatremia}} Excessive water consumption reduces or dilutes electrolyte levels in the body causing hyponatremia.
