''Note: This article is about chronic [[health]] conditions that cannot be treated completely using medicines alone.  For physical damage, see [[Injury]].  For treatable conditions, see [[Disease]].

'mtb' stands for 'Mean Time Between', and is how it's presented in the game files.

Some conditions can give rise to other conditions; the risk of this happening will diminish if the condition is treated.

==Chronic==
Ailments that come with age.

===Alzheimer's===
Progressive brain degeneration. As of Alpha 16, it has yet to have stages implemented where it becomes fatal, with the worst stage being 'Major'.

Progresses by 0.003 per day, meaning that it will take 333.33 days for it to reach full severity.

* '''Minor''' - begins as soon as it appears
** Symptoms:
*** Impaired consciousness (-5%)
*** Confused wandering (''mtb of 12 days'')
*** Forget memory thought (''mtb of 7 days'')

* '''Minor''' - begins at 20% severity
** Symptoms: 
*** Impaired consciousness (-10%)
*** Confused wandering (''mtb of 9 days'')
*** Forget memory thought (''mtb of 4 days'')
*** ''0.15%'' of conditional thoughts nullified

* '''Major''' - begins at 50% severity
** Symptoms:
*** Impaired consciousness (-15%)
*** Confused wandering (''mtb of 7 days'')
*** Forget memory thought (''mtb of 2 days'')
*** ''0.5%'' of conditional thoughts nullified

* '''Major''' - begins at 80% severity
** Symptoms:
*** Impaired consciousness (-20%)
*** Confused wandering (''mtb of 4 days'')
*** Forget memory thoughts (''mtb of 0.8 days'')
*** ''1%'' of conditional thoughts nullified

===Asthma===
Asthma is a chronic health condition where inflammation causes the airways to narrow, restricting the flow of oxygen to the lungs. It has yet to have a stage where it becomes fatal. Unlike other chronic diseases, Asthma can be contracted at almost any age, meaning it's not terribly uncommon to have an asthmatic person some time down the line. Asthma can be 'cured' via lung transplants, but this is less viable as of Alpha 16 due to the reduced medical potency of all medicines (except Glitterworld Medicine).

When not treated, it progresses by a rate of 0.25 per day, meaning it will take 2 days to reach full severity. <br>
The maximum severity for Asthma is 50% as of Alpha 16.

Good treatment will reduce the rate of progression by up to 0.8, meaning it will regress by 0.55 a day; it can be returned to its initial severity, but cannot be cured completely.

Asthma's severity will fluctuate depending on the quality of treatment received, with a treatment quality of 32% (the higher, the better) beginning to regress the stages of asthma.

* '''Minor''' - begins as soon as it's contracted
** Symptoms:
*** Impaired respiration (-5% per affected lung)

* '''Major''' begins at 30% severity
** Symptoms:
*** Impaired respiration (-15% per affected lung)

* '''Major''' begins at 45% severity
** Symptoms:
*** Impaired respiration (-25% per affected lung)

Treatment:
* Treated every {{ticks|420000}}

===Bad Back===
The older a colonist is, the more likely they're going to hurt their back one day (or just naturally develop one).

General Symptoms:
* Impaired movement (-30%)
* Impaired manipulation (-10%)

===Cataracts===
Cataracts are the clouding of the lens on your eyes which may occur spontaneously with age similarly to [[#Bad Back|bad back]]. Unlike bad back, cataracts are a very serious impairment, but technically treatable via [[Health|surgery]] of the eye. In an unmodded game, this is only possible using [[Bionic Eye|bionic eyes]].

General Symptoms:
* Impaired sight (-50% part efficiency per eye; resulting in 50% sight if both eyes are afflicted)

===Carcinoma===
A carcinoma (or cancer) is where mutated cells uncontrollably divide to form tumours, which then 'crowd out' normal bodily cells and hinder bodily function in that area. Carcinomas can be surgically removed (required a surgeon with at least 10 medicine skill), or healthy parts can be transplanted in some cases. Ordinary treatment (which can be performed by anybody) will prolong the development of a carcinoma or speed up remission, with better treatment being more effective.

A carcinoma typically starts out at 30% severity. There is a 30% chance that a carcinoma won't cause any pain whatsoever.

A cancer has 3 stages; growing, stable and remission.<br>
When growing, it progresses by 0.003 per day, meaning it will take 233.33 days for it to reach full severity from discovery. <br>
When stable, it neither grows nor regresses on its own. Treatment can however cause it to shrink. <br>
When in remission, it regresses by 0.002 per day, taking up to 500 days to disappear on its own.

Good treatment can slow progression by 0.0027 per day, meaning that the carcinoma will grow at only 10% of its original speed, and regresses over twice as fast.

* '''Minor''' - less than 15% severity
** Symptoms:
*** Little pain (+10%)
*** Reduced part efficiency (-10%)

* '''Minor''' - starts at 15% severity
** Symptoms:
*** Moderate pain (+20%)
*** Reduced part efficiency (-25%)

* '''Major''' - starts at 40% severity
** Symptoms:
*** Moderate pain (+35%)
*** Significantly reduced part efficiency (-50%)

* '''Major''' - starts at 60% severity
** Symptoms:
*** Acute pain (+50%)
*** Minimal part efficiency (-80%)

* '''Extreme''' - starts at 80% severity
** Symptoms:
*** Acute pain (+60%)
*** Minimal part efficiency (-90%)

* '''Extreme''' - 100% severity
** Symptoms:
*** Acute pain (+70%)
*** No part function (0% efficiency)
*** Destruction of affected part

Treatment:
* Treated every {{ticks|240000}}
* Can be surgically removed; this needs 6 medicine and a doctor of Medicine skill 10 or above, and is highly prone to failure

===Dementia===
Dementia is simply the functionality of the brain declining, and affects all cognitive functions.

General Symptoms:
* Impaired consciousness (-15%)
* Impaired speech (-40%)
* Impaired hearing (-40%)
* Confused wandering (''mtb of 5 days'')

===Frail===
As a pawn gets old, their physical form will deteriorate and will therefore not be as strong as they used to be. Can stack with a bad back.

General Symptoms:
* Impaired movement (-30%)
* Impaired manipulation (-30%)

===Heart Artery Blockage===
As one ages, plaque will build up in their heart's arteries, such as the coronary artery and the aorta (the main artery). Artery blockages in humanlikes can be 'cured' via a heart transplant, but there is currently no way to cure artery blockages in animals. 

Artery blockages progress by a base of 0.0007 per day, and is multiplied by a random factor between 0.5 - 3. <br>
This means that artery blockages can take anywhere from 7.937 to 47.619 in-game years from contraction to become fatal on its own, depending on how generous (or evil) RNG is feeling.

Besides killing directly, it can also start heart attacks which are fatal if not treated.

* '''Minor''' - starts upon contraction
** Symptoms:
*** Impaired blood pumping (-5%)
*** Heart attacks (''mtb of 600 days'')

* '''Minor''' - starts at 20% severity
** Symptoms:
*** Impaired blood pumping (-10%)
*** Heart attacks (''mtb of 500 days'')

* '''Major''' - starts at 40% severity
** Symptoms:
*** Impaired blood pumping (-15%)
*** Heart attacks (''mtb of 300 days'')

* '''Major''' - starts at 60% severity
** Symptoms:
*** Impaired blood pumping (-35%)
*** Heart attacks (''mtb of 200 days'')

* '''Extreme''' - starts at 90% severity
** Symptoms:
*** Impaired blood pumping (-60%)
*** Heart attacks (''mtb of 120 days'')

===Hearing Loss===
The ability to hear is hindered due to damage of delicate hair cells in the inner ear, but occurs naturally with age. Can't be 'treated' unlike cataracts.

General Symptons:
* Impaired hearing (-35% per ear)

==General==
These ailments generally appear in gameplay.

===Cryptosleep Sickness===

Occurs after having been in a [[ship cryptosleep casket]] or a [[cryptosleep casket]] for any amount of time. The colonists at the start of the game of the default scenario have a chance of starting with cryptosleep sickness, as they were in cryptosleep before crashing on the planet.

General Symptoms:
* Frequent Vomiting (''mtb of 0.125 days'')
* Impaired consciousness (x50%)

Treatment:
* Wears off after {{ticks|10000}}

===Food Poisoning===
Occurs after having eaten a contaminated meal. The chance of contamination is determined by the [[Food_Poison_Chance|cook's skill]] and the [[Room_stats#Cleanliness|cleanliness of the room]] where it was prepared.

General Symptoms:
* Sporadic Vomiting (''mtb of 0.35 days'')
* Impaired consciousness (x50%)

Treatment:
* Wears off after {{ticks|30000}}

===Toxic Buildup===
Occurs with exposure to [[Events#toxic fallout|toxic fallout]]. A colonist under a roof is protected from exposure. Prolonged exposure gradually increases the buildup level. Once a colonist returns to a roofed area their buildup severity will gradually decrease. The buildup severity occurs in stages. The later stages cause permanent [[Injury#Old Age|dementia]]; once caused, it does not wear off even after toxic buildup subsides.

Once in a safe area, severity reduces by 0.08 per day, meaning that it will take up to 12.5 days to eliminate all toxins accumulated in the body. However, colonists that reach such a stage are highly likely to develop further complications.

* '''Initial''' - begins at 4% severity.
** Symptoms:
*** Impaired consciousness (reduced by 5%)

* '''Minor''' - begins at 20% severity.
** Symptoms:
*** Impaired consciousness (reduced by 10%)

* '''Moderate''' - begins at 40% severity.
** Symptoms:
*** Impaired consciousness (reduced by 15%)
*** Vomiting (''mtb of 5 days'')
*** Dementia ('''permanent''', ''mtb of 146 days to develop'')
*** Carcinoma (''mtb of 438 days to develop'')

* '''Serious''' - begins at 60% severity.
** Symptoms:
*** Impaired consciousness (reduced by 25%)
*** Vomiting (''mtb of 1 day'')
*** Dementia ('''permanent''', ''mtb of 37 days'')
**** Carcinoma (''mtb of 111 days'')

* '''Extreme''' - begins at 80% severity. <br>At this stage the victim will fall unconscious and need rescue.
** Symptoms:
*** Unconsciousness (max 10%)
*** Vomiting (''mtb of 0.5 days'')
*** Dementia ('''permanent''', ''mtb of 13 days'')
*** Carcinoma (''mtb of 39 days'')

* '''Death''' - occurs at 100% severity.

==Surgical==
These ailments happen with medical operations.

===Anesthetic===
Used in surgery to make sure that a colonist is unconscious.

General Symptoms:
* Unconsciousness (sets to 10%)

Treatment:
* Wears off after {{ticks|15000}}
** Surgery is unaffected even if it wears off before finished

===Euthanasia===
Used to put [[colonist]]s or animals out of their misery, quietly.

Notes:
* Total loss of consciousness (death)
* Doesn't heal/get better

===Shut Down===
This happens to mechanical beings, similar to euthanasia.

Notes:
* Total loss of consciousness
* Doesn't heal/get better
