Loud breathing refers to the audible sounds produced during inhalation and exhalation. This can occur due to various factors, including physical exertion, respiratory conditions, or obstructions in the airways. Common causes include asthma, allergies, or obstructive sleep apnea, which can lead to increased noise during breathing. In some cases, loud breathing may indicate an underlying health issue that requires attention. It can be accompanied by other symptoms such as wheezing, coughing, or shortness of breath. If loud breathing persists or is associated with discomfort, it is advisable to consult a healthcare professional for evaluation and potential treatment.
