Does scoliosis effect pregnancy or a person having scoliosis goes through any issue during pregnancy?

Depends: Scoliosis is a label that includes curves that are so minor they are never recognized or only found by a chance x-ray. Some are so major that either side to side or rotary changes make breathing & functioning difficult. Since the major forms are rare, I suspect your question is about minor to moderate. This is one issue an OBGYN can answer based on the specifics of an exam.
