Two types of [[Dosha|dosha]] are: Prakrita (inherent state) and vaikrita [[dosha]] (acquired state). Prakrita [[dosha]] are observed at the time of conception and are responsible for the formation of [[Prakriti|prakriti]]. They are constant, and any change in them leads to death or trouble. They are responsible for the expression of individuality or phenotype of the person. Vaikrita [[dosha]] are produced as the waste of [[Ahara|food (ahara)]] and continuously circulate in the [[Sharira|body]] of fetus. They are responsible for health, and any disturbance in their physiological limits, either excess or decline, leads to [[Vyadhi|disease]]. Prakrita and vaikrita [[dosha]] always stay in connection with one another, and collectively, they are called sharirika [[dosha]]. A person can only control the vaikrita [[dosha]] through diet and lifestyle. [A.S. Sharira Sthana 8/4]<ref name="multiple9" /> </div>

The state of vata dosha can be diagnosed and assessed based on clinical features. The most presented clinical features of vata dosha are pain(shula), numbness(suptata), dryness (rukshta) rigidity ([[Stambhana|stambhana]]), [[Shosha Nidana|wasting (shosha)]] and harshness(parusha).[Cha.Sa. Sutra Sthana 20/12]

<div style='text-align:justify;'>

<div style='text-align:justify;'>

Disturbance, either excess or decline, leads to [[Vyadhi|disease]]. To manage and or prevent [[Vyadhi|disease]], the clinician must follow the theory of similarity and dissimilarity ([[Samanya Vishesha Theory|samanya- vishesha siddhanta]]) based on [[Rasa|rasa]] and food, which decline vata (shamaka) and [[Prakopa|aggravate vata(prakopa)]]. Controlling the increase of the vata dosha requires avoiding foods and ways of living that increase it,  while indulging in foods that reduce it (vata shamaka). Contrarily, the decline of vata is treated by consuming foods and leading lifestyles that stimulate it, rather than suppressing it.

Vata dosha can be assessed by its functionality either normal or abnormal through subjective methods like questionnaires and objective methods. There are some objectives methods which may be used to assess the functions of vata. Currently, there are no validated and standardized tools for [[Dosha|dosha]] assessment within the [[Sharira|body]].

The critical area of research is the preparation of a validated and standardization of questionnaires for vata kshaya, vata vriddhi, and normal functioning of vata to assess the state of vata. [[Guna|Guna]] based assessment of vata and incorporation of objectivity in assessment of vata through biological, immunological parameters is needed.
