John P. Newnham is a Pediatric Endocrinologist based in Nedlands, WA. His clinic is at 17 Monash Ave, Nedlands, WA 6009, Australia. He looks after babies, children, and families who need help with hormone and growth-related health issues, especially when things are starting from the newborn stage.
Many of the concerns he helps with can be quite complex, and they often need careful checks over time. This can include conditions like congenital adrenal hyperplasia (CAH) and congenital hyperinsulinism, where hormone balance and blood sugar can be affected. He also supports children with ongoing weight and metabolism issues, including obesity.
Newborn and early life problems are a big part of his work too. At times, babies are managing things like newborn jaundice, prematurity, or breathing and oxygen problems right after birth. He also helps with serious early conditions where the body’s chemistry can change, such as metabolic acidosis and lactic acidosis, and situations like hypoxia or cerebral hypoxia.
He also works with families dealing with blood pressure issues in infants and hypertension. That can be stressful, so the focus is on staying calm, checking the details, and making sure care is clear. If a baby has feeding and gut problems like necrotizing enterocolitis, that’s another area where early specialist input matters.
There are also other paediatric health concerns that can come up alongside endocrine problems. This may include hypospadias, undescended testicle, varicocele, and intersex traits. At times, he may be part of the care team when children have issues like gestational diabetes history, intrauterine growth restriction, or pregnancy-related liver and bile problems such as intrahepatic cholestasis of pregnancy.
John’s training is grounded in paediatric care and hormone health, which helps when the situation is urgent and the pathway can be unclear. Over time, he aims to bring order to the testing and follow-up, so families know what’s happening and what to watch for next. Keeping communication practical and easy to understand is part of the job.
While public details on research or clinical trials aren’t listed here, the main goal in his work is steady, hands-on care for kids with hormone and early-life medical needs.
