Ayurveda Tridosha Theory for Diagnosis of Diseases

Based on principles of ayurveda Tridoshas are 3 Doshas or 3 energetic forces in our body. They keep body healthy when they are in balanced condition and can cause diseases when imbalanced

According to ayurveda three doshas or three energetic forces control the activities of the body. These doshas are
Vata Dosha
Pitta Dosha
Kapha Dosha

VATA Dosha

The Vata dosha is the most important of the three doshas. It has been said in ayurveda classic books that “ pitta , Kapha and all other body tissues are considered lame without assistance of VATA .” Vata dominates the lower part of the body, which is below umbilicus. The movements of body fluid, metabolism, elimination of waste products, semen ejaculation, pushing the fetus out of body, relaying stimulus to brain and response to organs and tissues, heart beat, respiration, body movements etc are assisted by VATA. Vata dominated regions are intestines, lumbar region, ears, bones and skin.

Vata gets vitiated due to following reasons.

  • Suppression of natural urges like urination, defecation, hunger, thirst, etc.
  • Late nights.
  • Irregular food habits.
  • Talking in a high pitch.
  • Over physical and mental exertion.
  • Consumption of spicy, dry, bitter foods.
  • Exposure to severe dry and cold climate.
  • The opposites of above-mentioned reason normalize the vitiated vata.


The pitta dosha assists the body fire or Agni, which plays a major role in body’s metabolic activities. The locations where pitta dominates are digestive system, skin, eyes, brain, and blood. Pitta maintains body temperature. The secretions like digestive juices pigments like melanin (bhrajaka pitta), hemoglobin (ranjaka pitta) are all types of pitta.

Pitta is dominant in regions of Umbilicus, stomach, sweat, lymph, blood, eyes and skin.

Pitta gets vitiated due to following reasons.

  • Excess consumption of spicy, sour, salty foods.
  • Consuming alcohol in excess.
  • Over exposure to hot sunny climate.
  • Short temperedness.
  • Using dried vegetables.
  • Indigestion of food.

The opposites of above-mentioned reason normalize the vitiated pitta.


Kapha provides bulk to body, lubrications, moistness, fertility, stability, strength, and memory. Helps in binding process wherever necessary. This is heaviest of all doshas.
Kapha dominated regions are chest, neck, head, stomach, body fat, nose and tongue

Kapha gets vitiated due to following reasons.-

  • Sleeping in daytime.
  • Consuming sweets , chilled food, in excess.
  • Consuming fish, sesame, sugarcane, milk and milk products.

The opposites of above-mentioned reason normalize the vitiated kapha.
When these doshas are in balanced condition the body remains healthy. If these doshas get imbalanced the body succumbs to diseases.

Doshas get imbalanced frequently due to change in climate, seasons, lifestyles, diet etc. The treatment is to bring back the doshas to normalcy and expel the toxin or ama produced during the imbalanced condition
