Consists of ailments as obstinate skin diseases, hemorrhoids, diabetes, tuberculosis and asthma that arise primarily due to defects in the sperm (sukra) of the father – when it is called pitrija or the ovum (sonita) of the mother – when it is termed matrja.
Undigested food, abnormal behaviour, addiction of any type and stressful situations affect the reproductive elements of both the male and female, resulting in a defective foetus.
If diet and / or conduct of the mother aggravates vata, the foetus might end up with deformities as kyphosis (hunchback), blindness and dwarfism; increased pitta may cause alopecia and yellowish pigmentation of skin; and enhanced kapha might result in albinism.
Arise out of any dietary or behavioural disturbance brought about by an imbalance in any one of the three vital physical energies (Tridoshas) or the three vital mental energies (Trigunas).
Thus constitutional disorders are of two types : somatic (Sharirika) & psychic (Manasika).
Undergoing any trauma causing experience – external or internal – leads to this.
External trauma is induced by injuries inflicted by sharp instruments and bites of animals or venomous insects.
Stress and overstrain lead to internal trauma.
Brought about by changes in the nuances of seasonality.
Sometimes the body fails to adjust itself to the sudden and abnormal climatic changes – extreme cold might lead to frostbite and rheumatic disease. While extreme heat may cause sunstroke or fever.
Either born out of natural calamities as lightning, earthquakes, floods and the invisible, malignant forces of nature.
Or contacted through sexual & physical intimacy and sharing of food, plates, bed, clothes, towels and cosmetics with effected friends & relatives.
Or as a result of sheer jealousy.
Even the healthiest of people are struck by hunger, thirst, sleep, death or senility.
Brought about by functional, organic and natural changes in the body.
In Ayurveda, physicians try to assess the symptoms of these diseases as much as the nature of ailment and its root causes (nidana). This is of utmost importance in ensuring correct choice of remedial & preventive measures for treatment of the disease. For otherwise, even after therapy, one might not get the desired response and there would remain a chance of recurrence.
The early signs and symptoms (purvaroopa) provide useful warnings and the opportunity for taking necessary action before a disease can assume dangerous magnitudes. The main signs and symptoms (roopa) reflect the true nature and intensity of the disease. Another oft used method of diagnosis is exploratory therapy (upasaya) which uses diet, medicines and routines to detect diseases otherwise difficult to diagnose. Acting either against the cause of disease or the disease itself or producing relief. For example a swelling that is alleviated by an oily & hot massage, is obviously caused by an imbalance of vata.
