What does a funeral home do to a bloated body?

This would depend on if the bloating was due to internal gas or water. In a case of internal gas when pressure inside the stomach causes the deceased's stomach to swell up, a mortician or funeral director, will relieve the body of the stress by making an incision into the stomach to release the case. This is normally achieved, by incision three finger lengths down from the middle of the breast bone. In the case of bloating by water, other than remove excess water from the deceased, there is not much more that can be done apart from embalming, were the visual affects of bloating are slightly decreased.
