Are you experiencing a persistent cough weeks after recovering from a cold? You’re not alone.
It’s a scenario familiar to many, as highlighted in a recent article in the Canadian Medical Association Journal. According to research, 11% to 25% of adults encounter what’s known as a post-infectious cough after battling a respiratory infection.
What causes this lingering cough? Dr. Omid Mehdizadeh, an otolaryngologist at Providence Saint John’s Health Center, explains that post-viral coughs stem from increased inflammation in the respiratory system, affecting areas such as the nose, throat, and lungs. This inflammation heightens bronchial sensitivity and triggers excess mucus production, hindering its clearance.
But fear not, as these coughs typically resolve on their own within three to eight weeks. However, if the cough persists or becomes bothersome, there are steps you can take. Dr. Chantel Strachan, a Primary Care Physician at Columbia University Irving Medical Center, suggests conservative measures like over-the-counter cough suppressants, intranasal steroids for postnasal drip, humidifiers, and lozenges.
It’s essential to avoid unnecessary medications like antibiotics or steroids, as studies show that most post-infectious coughs improve naturally over time. Additionally, reliance on certain medications may strain medical resources and contribute to environmental concerns.
How can you differentiate between a post-infectious cough and a more serious condition? Dr. Mehdizadeh advises that post-infectious coughs typically manifest as dry, hacking coughs. Conversely, a wet cough accompanied by symptoms like shortness of breath or chest pain warrants medical evaluation.
In summary, while post-infectious coughs are a common nuisance, they are generally benign and manageable with conservative measures. However, if symptoms persist beyond eight weeks or are accompanied by concerning signs, seeking medical advice is prudent.
