Exercise intolerance is a condition where the patient is unable to do physical exercise at the level or for the duration that would be expected of someone in his or her general physical condition, or experiences unusually severe post-exercise pain, fatigue, or other negative effects. Exercise intolerance is not a disease or syndrome in and of itself, but a symptom.
Since there are many possible specific reasons why exercise could be inhibited, this is a rather slippery term. For instance, the patient may experience unusual breathlessness (dyspnea), muscle pain (myalgia), or increasing muscle weakness while exercising, or may, after exercise, experience severe headache, nausea, dizziness or extreme fatigue. In most cases, the specific reason that exercise is not tolerated is of considerable significance when trying to isolate the cause down to a specific disease.
Famous quotes containing the words exercise and/or intolerance:
“I would not that death should take me asleep. I would not have him meerly seise me, and onely declare me to be dead, but win me, and overcome me. When I must shipwrack, I would do it in a sea, where mine impotencie might have some excuse; not in a sullen weedy lake, where I could not have so much as exercise for my swimming.”
—John Donne (c. 1572–1631)
“In economics, we borrowed from the Bourbons; in foreign policy, we drew on themes fashioned by the nomad warriors of the Eurasian steppes. In spiritual matters, we emulated the braying intolerance of our archenemies, the Shi’ite fundamentalists.”
—Barbara Ehrenreich (b. 1941)
