The body keeps the score

I wonder how previous trauma would affect the physical body and how it would be manifested in innies. The severance process will remove memories. But would it also remove bodily responses? If Helena was forced to do something during her childhood (forced to eat raw eggs!) and has managed to respond in a calculated way (while she feels turmoil in her belly) would Helly R feel immense negative feelings about raw eggs? Can physical response to old trauma be the constant thing in all Gemma versions? An anchoring point? I don’t think something like this has been explored in the series. I was wondering what y’all think about it. What can be an anchoring point apart from love?
