About of Sebastian K. King

Sebastian K. King is a Pediatric Gastroenterologist based at 50 Flemington Road, Melbourne, VIC, Australia.


Kids’ gut health can be complicated. Many families come in when a child has ongoing tummy pain, feeding problems, or bowel changes that just don’t settle. In many cases, this can involve reflux in infants, long-lasting constipation, or gut issues linked to nerves and bowel control.


Sebastian also looks after children with bowel conditions such as Crohn’s disease and ulcerative colitis, as well as other forms of colitis. At times, symptoms like diarrhoea, bleeding, or poor growth can be part of the picture, so care needs to be steady and practical from day to day.


Some patients need help with gut movement and bowel emptying. This can include chronic idiopathic constipation (CIC) and problems like encopresis, where stool leakage happens after long constipation. Others may have bowel incontinence due to neurogenic bowel, or issues that affect how the gut works overall.


There are also children with bowel problems that are present from birth. These may include Hirschsprung disease, intestinal pseudo-obstruction, imperforate anus, and short bowel syndrome. For congenital bowel narrowing or blockage, such as duodenal atresia or small bowel problems, the focus is on making sure children get the right tests and support early.


When unusual connections or openings are part of the condition, this might include oesophageal atresia, tracheoesophageal fistula, or other gastrointestinal fistulas. Some children are also managed after bowel surgery, including ileostomy or colostomy, and may need ongoing help with recovery and nutrition.


Endoscopy can be part of the workup too. This helps when symptoms need a closer look inside the gut. Alongside that, care often covers related problems like malabsorption, gastro-intestinal infection such as viral gastroenteritis, and issues that can affect digestion and overall hydration.


In the bigger picture, the goal is to give families clear next steps and calm guidance, while working through the diagnosis and treatment plan for each child. If a situation is complex, a careful, child-focused approach matters most.
