Analysis

Effects

A bionic stomach improves a pawn's metabolism by 25%. This, in turn, slightly improves the rest rate multiplier by about 8%, meaning the colonist will require less sleep. The bionic stomach is a cheaper way to reduce time sleeping than upgrading to a royal bed, however both can be combined.

Installing a stomach can be used to instantly treat gut worms as the new stomach replaces the diseased part. With it installed, further infections are also prevented.

Of all the bionic parts in the game, excluding the bionic spine, it is likely the least useful, only improving rest rate multiplier. However, it is still worth installing if there is one to hand, as this bonus is still significant.

Eating speed and food poisoning chances are unaffected.
