Hyperventilation Symptoms
Symptom Checker: Symptoms & Signs Index
Medical Author: Melissa Conrad Stöppler, MD
Hyperventilation refers to overbreathing, in which
ventilation exceeds the
metabolic demand, and
its related physiological consequences. Excessive breathing can cause dizziness, lightheadedness,
weakness, shortness of breath, a sense of unsteadiness, muscle
spasms in the hands and feet, and a tingling feeling around the mouth and fingertips. All of these symptoms are the result of
abnormally low levels of carbon dioxide in the blood caused by overbreathing.
The term hyperventilation syndrome (HVS) is sometimes used to describe the
effects of hyperventilation observed in an emergency department setting. Many
acute (sudden onset)
cases of hyperventilation arise from panic, anxiety, and other emotional
conditions. Hyperventilation, particularly chronic hyperventilation (that
persists over time), can also be due to a range of
medical conditions.
The opposite of hyperventilation is termed hypoventilation
(underventilation).
