👉 Catarrh, also known as a nasal obstruction, is a condition characterized by the difficulty in breathing due to mucus or fluid buildup in the nose. The exact cause of catarrh can vary widely depending on factors such as allergies, asthma, sinusitis, and other respiratory conditions. Symptoms can include coughing up mucus, sneezing, and difficulty swallowing. Treatment may involve medications or nasal irrigation to relieve the congestion.
