Key Questions Answered
A cough lasting three weeks or more is considered a serious health risk and can indicate conditions like pulmonary tuberculosis, asthma, allergies, or chronic obstructive pulmonary disease, requiring immediate medical examination.
Symptoms associated with tuberculosis include phlegm or blood in the sputum, chest pain, weakness, loss of appetite, unexplained weight loss, fever, and night sweats.
Long-term smokers with a persistent cough are at a higher risk of developing Chronic Obstructive Pulmonary Disease (COPD), which causes long-term damage to the airways and lungs and gradually increases breathing difficulties.
