Gaston B. Arnolda is a paediatrician based in Sydney, working from Level 6, 75 Talavera Road, Sydney, NSW 2109, Australia. He looks after children from newborn stage through the early years, with a calm, practical approach to common illnesses as well as some more serious conditions. Parents often want answers they can understand, and he aims to keep things clear and steady from the first appointment to follow-up care.
In day-to-day practice, he treats issues like newborn jaundice and helps families whose babies are dealing with breathing problems in infancy, including infant respiratory distress and related conditions. He also sees babies who are premature, and can support care needs where ongoing monitoring matters. At times, he manages concerns such as croup and other upper airway or throat problems, plus conditions like laryngitis and tonsillitis.
He also works with children who have ongoing digestive or feeding concerns, including gastroesophageal reflux disease (GERD) and reflux in infants. Ear issues come up often too, including otitis media with effusion, and he helps work out what’s going on and what to do next. For some kids, symptoms can be linked to more than one problem, so he focuses on checking the full picture and making a plan that fits the child’s age and situation.
There are times when paediatric care needs to move quickly, especially when symptoms could point to something urgent. His service list includes serious conditions such as strokes, heart attack, and colorectal cancer, so he’s used to the kind of careful assessment those cases require. Over time, his work covers a wide range of paediatric presentations—from breathing and throat problems to reflux and infant jaundice—so families can get support when they need it most.
