Vyādhi literally means ‘disease’.

Āyurveda or the science of health and longevity, categorizes vyādhi or roga[1] into four groups:

  1. Āgantuka - coming from external sources or accidents
  2. Śārīra - arising in the body due to the disturbance of the balance of the three humours viz., kapha, vāta and pitta
  3. Mānasa - of the mind, due to jealousy, anger, lust and so on
  4. Svābhāvika - natural due to hunger, thirst, old-age, sleep etc.

These diseases may be caused by improper lifestyle and also by the karma of the previous lives.


  1. Roga means disease.
