Q. Hi Fitz, Why is that we feel like puking or vomiting during intense workouts? Is it a bad indication or health threat? I saw on the Biggest Loser that there were those who puked. However, I felt it just recently on my 20 minute incline treadmill workout and it gave me the creeps. Did I do something wrong? Am I supposed to have myself checked with a doctor? Thanks, Kassy
A. Hi Kassy. Thanks for the great question. There are a bunch of possible causes for your nausea, and most are not worthy of worry. Vigorous exercise takes it's toll on all the different parts of our body; not just our legs, arms and abs. It effects our respiratory, cardiovascular, nervous, and digestive systems (amongst others) as well. Most of the effects of challenging exercise are great, some of the effects though are temporarily not-so-great. I found a study by Dr. R. Rafoth, M.D., The Athlete and the G.I. Tract which describes the causes of exercise induced nausea and other G.I. symptoms which I summarize below.
Some of the factors that can lead to exercise induced nausea are:
1. Presence of symptoms in a non exercising period, such as Irritable Bowel Syndrome.
2. Age. More symptoms occur in younger athletes.
3. Gender: Women are more likely to experience exercised induced nausea, completely unrelated to ones menstrual cycle.
4. Diet: There is an increased incidence of upper abdominal symptoms in athletes who consumed:
-
too big a meal too close to exercise
-
fats
-
hyper-tonic drinks, glucose syrups, honey/maple syrups
-
foods high in dietary fiber
-
high protein diets
