With changes in weather, many people encounter coughing problems. Usually, in such cases, people take expectorants on their own. Some experience relief, while others' cough persists for several days. Doctors explain that coughing is a natural protective mechanism of the body designed to expel mucus, dust, irritants, and microbes from the respiratory tract.
A cough caused by a common cold, allergy, or mild respiratory infection usually goes away on its own, and there is no need to worry about it. However, sometimes a cough that seems minor can be a sign of a more serious illness. Therefore, it is crucial to know when this symptom should not be neglected.
Dr. Vivek Nangia, Head of Pulmonology at Max Hospital in Saket, told Aajtak.in about this issue. He emphasized that if five specific symptoms appear along with the cough, immediate medical attention is necessary.
Firstly, if the cough lasts for three to four weeks. Dr. Vivek notes that if the cough starts and continues for three to four weeks, it indicates that it is not ordinary. This may suggest a serious infection in the body, including asthma, pneumonia, or tuberculosis. With such a prolonged cough, one should consult a doctor immediately; a specialist can accurately diagnose the condition using X-rays and other tests.
Secondly, if the cough produces phlegm containing blood. The appearance of a large amount of phlegm during a cough should not be ignored, especially if blood is visible in it. Hemoptysis can be a sign of a respiratory infection, bronchiectasis, or tuberculosis. In some cases, it may also indicate a lung tumor, especially in smokers. If blood reappears, a medical examination must be urgently undergone.
Thirdly, if the cough is accompanied by difficulty breathing or wheezing. Attention should be paid to breathing problems, chest tightness, wheezing, or reduced ability to exercise without an apparent reason. These signs may indicate asthma, COPD, pneumonia, or other heart and lung diseases. Sudden or excessive shortness of breath, especially if accompanied by chest pain, blue lips, confusion, or decreased oxygen levels, requires immediate medical assistance.
Fourthly, if there is fever, weight loss, or night sweats. Viral infections usually resolve on their own. However, if the cough is accompanied by persistent or frequent fever, profuse night sweating, loss of appetite, severe fatigue, or unexplained weight loss, further testing should be conducted.
Fifthly, attention should be paid to a change in the nature of the cough without an obvious reason. One should pay close attention to a cough that suddenly becomes more frequent, deeper, or painful, or where the amount of phlegm increases, or its overall character changes. This is particularly relevant for smokers or former smokers. Increased attention is also required for people over 40 years old or those frequently exposed to tobacco smoke, air pollution, or dust in the workplace.
