This means to tell that the pain or grief can be manifested at the body, speech and or mental level. Vyadhi is that which causes grief or pain of different forms.
To put in simple words, Vyadhi is that which causes various types of pain or grief at one or the other of the physical, speech or mental levels after afflicting the Chikitsa Purusha.

Imbalances occurring in the dhatus of the body are called Vikara or Vyadhi.

Imbalance of all these elements of the body and mind and absence of signs of balanced health is called Vyadhi.

The effect of these diseases is the manifestation of symptoms like aruchi (anorexia) etc. this means to tell that dosha-dushya sammurchana leads to the formation of diseases like jwara and as a resultant of these diseases the symptoms like aruchi etc are manifested.
