	'''Exercise intolerance''' is a condition characterized by an inability to perform physical activities at the level or duration that would be expected based on an individual's age, sex, and physical condition. It is often associated with feelings of fatigue, breathlessness, or muscle pain during or after exercise. Exercise intolerance can be a symptom of various underlying health issues, ranging from cardiovascular and respiratory diseases to metabolic disorders and musculoskeletal problems.		{{SI}}

'''Exercise intolerance''' is a condition characterized by an inability to perform physical activities at the level or duration that would be expected based on an individual's age, sex, and physical condition. It is often associated with feelings of fatigue, breathlessness, or muscle pain during or after exercise. Exercise intolerance can be a symptom of various underlying health issues, ranging from cardiovascular and respiratory diseases to metabolic disorders and musculoskeletal problems.

==Causes==
Exercise intolerance can be caused by a wide range of conditions, including but not limited to:

* [[Cardiovascular diseases]]: Conditions such as [[heart failure]], [[coronary artery disease]], and [[peripheral artery disease]] can impair blood flow, leading to reduced oxygen supply to muscles during exercise.
* [[Respiratory diseases]]: Diseases like [[chronic obstructive pulmonary disease]] (COPD), [[asthma]], and [[pulmonary fibrosis]] can limit lung function, making it difficult to maintain adequate oxygen levels during physical activity.
* [[Metabolic disorders]]: Conditions such as [[diabetes mellitus]], [[thyroid disorders]], and [[mitochondrial diseases]] can affect the body's energy production and utilization, leading to exercise intolerance.
* [[Musculoskeletal problems]]: Issues such as [[arthritis]], [[fibromyalgia]], and [[muscular dystrophies]] can cause pain or weakness that limits physical activity.
* [[Chronic fatigue syndrome]] (CFS) and [[myalgic encephalomyelitis]] (ME) are also associated with significant exercise intolerance, often exacerbated by physical activity.

==Symptoms==
Symptoms of exercise intolerance may include:

* Unusual or excessive fatigue during or after physical activity
* Shortness of breath or difficulty breathing during exercise
* Muscle pain or weakness during or after exercising
* Dizziness or lightheadedness associated with activity
* Rapid heartbeat or palpitations during physical exertion

==Diagnosis==
Diagnosing exercise intolerance involves a thorough medical history, physical examination, and often, specific tests to identify underlying causes. Tests may include:

* [[Cardiopulmonary exercise testing]] (CPET) to assess cardiovascular and respiratory function during exercise
* Blood tests to identify metabolic disorders
* Imaging studies, such as echocardiograms or stress tests, to evaluate heart function
