Educational, not medical
The information on this site and provided in Erst's fitness, nutrition, and education services is for general educational purposes only. It is not medical advice, and it is not a substitute for care from your physician, midwife, or other qualified healthcare provider.
Talk to your provider first
Always consult your healthcare provider before beginning or changing an exercise or nutrition program during pregnancy or postpartum, and about any questions you have regarding a medical condition. Never disregard or delay professional medical advice because of something you read here.
Scope of practice
Erst's services are provided by a certified childbirth educator, trained birth doula, and certified perinatal fitness specialist — not a physician, and not a New York State certified dietitian-nutritionist. Where a medical condition is being treated, Erst works alongside your medical team and does not diagnose, treat, or manage medical conditions.
Emergencies
If you think you may be experiencing a medical emergency, call 911 or contact your healthcare provider immediately.
