Yellow sputum from a cold is not a cure. Yellow sputum is a sign of a viral cold secondary to a bacterial infection. Colds are usually caused by viral infections, and patients usually experience symptoms such as cough, runny nose, sneezing, nasal congestion, fatigue, and aching limbs. Coughing and sputum caused by colds are usually white foamy sputum or white mucus sputum, and yellow sputum may appear if it is secondary to a bacterial infection. For those who have a cold and spit up yellow sputum, it can be treated by taking antibiotics such as amoxicillin or cefixime to fight infection. At the same time, patients should pay attention to keeping warm, eating a balanced diet and exercising appropriately in order to improve immunity and enhance the ability to fight viruses. Spitting yellow sputum can also be caused by other diseases, such as acute sinusitis, acute pharyngitis and so on. If the symptoms do not improve or worsen, it is recommended to consult a doctor in a timely manner, complete the examination, clarify the cause of the disease and follow the doctor’s instructions.
