POOJA KOTHARIMom of a 8 yr 5 m old boy4 months agoA. A persistent cough lasting for over a month can be concerning, especially if the cause is not clear and medications are not helping. There are several potential reasons for this, including:
Allergies: Allergic rhinitis or asthma can cause chronic coughing, especially if your child is exposed to allergens like dust, pollen, or pet dander. Sometimes, allergies don't show obvious symptoms other than a persistent cough.
Post-nasal drip: If your child has had a cold or upper respiratory infection, mucus may be dripping down the back of the throat, causing irritation and coughing.
Asthma: This is a common cause of a chronic cough in children. Asthma-related coughing often worsens at night or during physical activity.
Environmental factors: Dry air, exposure to smoke, or living in an area with high pollution could also trigger a persistent cough.
Gastroesophageal reflux disease (GERD): Sometimes, acid reflux can cause coughing, especially at night or after meals.
Infections: Though a month-long cough is unusual, some respiratory infections, like a lingering viral infection, can cause a prolonged cough. Whooping cough (pertussis) is also something to consider if the cough is severe and rhythmic.
Since the pediatrician is unable to find a clear cause, it might be a good idea to get a second opinion, and possibly ask for further tests like an allergy test, chest X-ray, or a referral to a pediatric pulmonologist or an ENT specialist to explore other possibilities.
