Optimal care for women who are obese or overweight should involve a transdisciplinary and multi-specialty care approach, and should not be limited to managing the complications that arise during pregnancy. Recognising this concept is key to improving long-term outcomes for both mother and offspring. This multidisciplinary approach should include both medical (eg, hypertension, diabetes, dyslipidaemia) and social determinants of health (eg, diet, exercise, pregnancy planning).
