Chronic coughs lasting over eight weeks require prompt diagnosis to identify underlying causes such as infections, allergies, or reflux. Medical evaluation includes history, physical exams, and diagnostic tests like chest X-rays and lung function assessments. Early intervention helps prevent complications and provides relief from persistent coughing, sleep disturbances, and fatigue.

A cough lasting longer than eight weeks in adults or four weeks in children is classified as a chronic cough, which can significantly disrupt daily activities. Persistent coughing accompanied by symptoms like blood-streaked sputum, shortness of breath, or severe fatigue requires prompt medical attention. Causes include infections, allergies, acid reflux, asthma, or side effects from medication. Diagnosis begins with patient history and physical exams, with tests such as chest X-rays, sinus imaging, or lung function studies conducted if needed. Early identification and treatment of the underlying issue are key to relief.
Persistent coughs can lead to complications like sleep disturbances and exhaustion. Recognizing associated symptoms such as nasal congestion, throat infections, or acid reflux is essential. Certain medications may also cause chronic coughing. Diagnostic procedures include chest and sinus X-rays, lung function tests, and possibly endoscopy if the cause remains unclear. Children typically undergo chest X-rays and spirometry. Early diagnosis enables targeted treatment, addressing the root cause to alleviate symptoms and prevent further health issues.
