👉 The Christmas Flu, also known as the Christmas Respiration or Post-Natal Respiratory Syndrome, is a rare condition characterized by a sudden onset of respiratory distress in women who have recently given birth. It is often triggered by the hormonal changes and physical stress associated with childbirth, leading to an overproduction of mucus in the respiratory tract. This excessive mucus can obstruct airways, causing difficulty breathing and potentially leading to pneumonia or other respiratory complications. Symptoms typically appear within a few days to a week after delivery and can include wheezing, coughing, shortness of breath, and chest tightness. Treatment often involves supportive care such as oxygen therapy, bronchodilators, and sometimes antibiotics to prevent infection.
