A '''bionic stomach''' is an organ replacement that has 125% efficiency, and increases [[metabolism]] by 12.5% (metabolism is the average of stomach and liver efficiency).

== Acquisition ==
Bionic stomachs can be crafted at a [[{{P|Production Facility 1}}]] once the [[Research#{{P|Required Research}}|{{P|Required Research}}]] research project has been completed. They require {{Required Resources}}, {{Ticks|{{P|Work To Make}}}} of work, and a [[{{P|Skill 1}}]] skill of {{P|Skill 1 Level}}.

They can also be [[Trade|bought]] from exotic traders, [[Empire]] traders, and at [[Outlander]] [[faction base]]s. They are also sometimes offered as a [[quest]] reward.

== Summary ==
=== Body part ===
A bionic stomach replaces the user's organic stomach. The bionic stomach has a part efficiency of 125%. This not only fully replaces the functionality of a normal stomach - when coupled with the stomach body part having a [[Metabolism]] importance of 50%, it results in an increase in metabolism of {{+|12.5%}} over natural. Metabolism, in turn, improves the [[rest rate multiplier]] by {{+|3.75%}}, meaning the colonist will require slightly less sleep. 

[[Eating]] capacity, [[eating speed]], and [[food poisoning]] chances are unaffected.

=== Other effects ===
Additionally, all artificial stomachs are immune to [[gut worms]], and installing one will instantly cure the disease. Unlike the [[Royalty DLC]] stomach replacements, [[EMP]]ing a pawn with a bionic stomach will not force them to vomit. 

=== Installation ===
Installing a bionic stomach requires {{ticks|2500}} of work, 2x medicine of ??{{Check Tag|What Quality|Herbal, Industrial or Glitterworld?}} quality or better, and a [[Skills#Medical|Medical skill]] of 5.

Removing a bionic stomach requires {{ticks|2500}} of work, 1x medicine of ??{{Check Tag|What Quality|Herbal, Industrial or Glitterworld?}} quality or better, and a [[Skills#Medical|Medical skill]] of ?.

If the operation fails, the part has a chance{{Check Tag|What Chance?}} to be destroyed.

== Analysis ==
Of the [[bionic]]-level parts in the game, the bionic stomach offers one of the weakest improvements to a pawn. It gives a 3.75% increase in sleep efficiency, or, for a standard 8 hour sleep cycle, a savings of just over 17 minutes/day - a 1.8% increase in waking hours/day. [[Gut worms]] aren't often a major threat for a colony that can make or buy bionic parts. But as there's still an improvement, spare bionic stomachs are still worth installing (unlike functionally equivalent "replacements" like the [[bionic spine]]). 

The [[bionic heart]] is superior to the stomach, as it improves sleep efficiency by 8%, but is slightly more expensive. However, both bionic hearts and stomachs can be used together. A stomach is still cheaper than a [[royal bed]], and doesn't have the massive power costs of a [[sleep accelerator]]{{IdeologyIcon}}. All four options do not conflict with each other; the only downside is cost.

===Stomach comparisons===
{{Royalty|No category}}
The [[Royalty DLC]] introduced a number of Stomach replacements with their own advantages and disadvantages. All three of these variants include the benefits offered by the bionic stomach in addition to their unique benefits however they are also susceptible to [[EMP]], causing the pawn to vomit uncontrollably for a short length of time. 

====Sterilizing Stomach====
In addition to the normal benefits of a bionic stomach, the [[sterilizing stomach]] eliminates the risk of food poisoning at the cost of vulnerability to EMP. 

====Reprocessor Stomach====
In addition to the normal benefits of a bionic stomach, the [[reprocessor stomach]] reduces the amount of food a pawn requires by 25% at the cost of vulnerability to EMP. 

====Nuclear Stomach====
The [[nuclear stomach]] combines the benefits of all other stomachs and reduces the amount of food a pawn requires by a whopping 75%, at the cost of vulnerability to EMP and inflicting torso [[cancer]] on average once 120 in-game days.
