It is crucial to correctly diagnose and determine the type of reflux in infants. Generally, reflux observed after each feeding, with small amounts of spit-up, no bile or blood in the vomit, and good overall development, is considered physiological (normal). However, if there are signs such as a stagnation in the baby's weight gain or actual weight loss, pathological reflux should be suspected, and a detailed medical evaluation is necessary. Untreated pathological reflux can lead to various serious health problems in infants and may pave the way for the development of other diseases in the long term. Major complications include weight loss, growth retardation, pain due to esophageal irritation, and loss of appetite. Disturbances in sleep patterns, restlessness, and difficulty falling and staying asleep may occur. Continuously recurring vomiting increases the risk of milk or stomach contents entering the windpipe (aspiration), leading to frequent lung infections. Furthermore, damage to the vocal cords may occur, and respiratory problems such as excessive wheezing or rattling due to bronchial obstruction in the airways can be observed.
