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:
“In the case of a deliberate, palpable, and dangerous exercise of ... powers not granted by the compact, the States ... are in duty bound to interpose for arresting the progress of the evil, and for maintaining within their respective limits the authorities, rights, and liberties appertaining to them.”
—James Madison (1751–1836)
“The revolutionary spirit is mighty convenient in this, that it frees one from all scruples as regards ideas. Its hard absolute optimism is repulsive to my mind by the menace of fanaticism and intolerance it contains. No doubt one should smile at these things; but, imperfect Esthete, I am no better Philosopher. All claim to special righteousness awakens in me that scorn and anger from which a philosophical mind should be free.”
—Joseph Conrad (1857–1924)
