Per this classification, ''nidana'' could be of three types:

1. Asatmyendriyartha samyoga (Abnormal contact of the Indriyas, i.e., sensory & motor organs): Excessive utilization, underutilization or improper utilization of sensory and motor organs with their objects is called as Asatmyendriyarth Samyoga.

#'''''Asatmyendriyartha Samyoga''''' (Abnormal contact of the ''Indriyas'', i.e., sensory and motor organs): Excessive utilization, underutilization or improper utilization of sensory and motor organs with their objects is called as ''Asatmyendriyarth Samyoga''.

2. Pragyaparadha (intellectual errors): The errors in one’s dhee (intellect), dhriti (restraint) and smriti (memory) lead to improper activitites. These result in improper activities of body, mind and speech leading to vitiation of dosha.  

#'''''Pragyaparadha''''' (intellectual errors): The errors in one’s ''dhee'' (intellect), ''dhriti'' (restraint) and ''smriti'' (memory) lead to improper activitites. These result in improper activities of body, mind and speech leading to vitiation of ''dosha''.  

3. Parinama (changes in the timings and in age): Changes in weather conditions or climate could lead to changes in environment that cause disease. Also, as one ages, exposure to environmental elements could afflict a person adversely. These are collectively termed parinama.

#'''''Parinama''''' (changes in the timings and in age): Changes in weather conditions or climate could lead to changes in environment that cause disease. Also, as one ages, exposure to environmental elements could afflict a person adversely. These are collectively termed ''parinama''.

These three types of nidana of diseases imply that everyone has to use his sensory and motor organs in a proper way for maintaining health. Also, one should try to understand his/her own body and mind and exercise restraint or moderation wherever required intellect for his health - with regards to his body, mind and speech. Similarly, one should always behave and act according to the season, environment (location, etc.) and one’s age.

Another classification is as follows:

Another classification is as follows:

1. Doshahetu – These causes are directly responsible for the vitiation of doshas and that particular vitiated dosha becomes the cause of the disease.

#''Doshahetu'' – These causes are directly responsible for the vitiation of ''doshas'' and that particular vitiated ''dosha'' becomes the cause of the disease.

2. Vyadhihetu – Such specific causative factors are directly responsible for the specific type of diseases. E.g., the use of sheetoshnaviparyaya (using hot and cold things at same time repeatedly) is a specific cause of kushtha (skin disease).

#''Vyadhihetu'' – Such specific causative factors are directly responsible for the specific type of diseases. E.g., the use of ''sheetoshnaviparyaya'' (using hot and cold things at same time repeatedly) is a specific cause of ''kushtha'' (skin disease).

3. Ubhayahetu – These causes are responsible for the vitiation of doshas as well as specific diseases e.g. continuious intake of sweets, unctuous and heavy diet is the cause of kaphadushti (doshahetu), as well as for kaphadosha dominant disorders (vyadhihetu) like sthaulya (obesity) and madhumeha (diabetes).
