why am i coughing so much

Coughing a lot can happen due to several common causes such as infections (cold, flu, bronchitis), asthma, allergies, exposure to irritants like smoke or pollution, gastroesophageal reflux disease (GERD), postnasal drip, or certain medications like ACE inhibitors. It can also be a lingering effect after respiratory infections or a sign of chronic conditions like chronic obstructive pulmonary disease (COPD) or other lung diseases. If the cough lasts a long time, worsens, or is accompanied by other symptoms, medical evaluation is suggested to determine the exact cause.
