Dr Oscar Serrallach  MBChB, FRACGP

Dr Oscar Serrallach’s patients benefit from his diverse experience and thirst to remain at the cutting edge of wellness medicine. A thirst that led him down the path of studying and practicing functional medicine, whilst addressing the multi factorial aspects of health and well being.

He is a leader in the field of postnatal health and it was through the experience of his own family and the lens of functional medicine that he came to realise the huge impact that nutrition, lifestyle and the environment have on the postnatal period. Oscar has spent the past eight years devoted to the identification and treatment of Postnatal Depletion, which he suspects up to 50% of mothers suffer, to some degree.
