Ayurveda believes that three doshas are the governing factors of body and they are vat pit and kaph. There perfect balance in body means health and any imbalance is the cause of disease. These three are further classified into five sub parts and each is assigned a particular task in body and has its own classical signs and symptoms. As in the present context we are concerned with kaphaj imbalance so i expand my reply to same. Here kaph is the greasy thick or lubricating matter present in body and being more precise it is type Avalambak kaph:- [It is present in the chest. It constitutes the myocardial and Alveoli ,and pericardial fluids. It supports and gives strength to the heart, and lungs ] when this type of kaph is increased due to over production or blockade of micro channel that flow it , it starts accumulating, symptoms depend on the area of accumulation.This causes shortness of breath
or tightness in chest or running nose and sneezing
crepts and wronchi in lungs if it accumulates in sinuses
headache is associated patient feel lethargic and feels no interest in daily chores. parameters to measure in degree is not part of ayurveda but this factor is covered under four headings 1. sanchaya 2. sthan shansharay 3prakop 4. prashman i.e. snchaya is the accumulation without causing any discomforts as it is minor but when accumulation continues then it moves to surrounding areas and this is sthan shansharay now accumulation starts at other locations also and after this at the stage of prakop symptoms appear and patient makes above mentioned complaints and when treatment is offered and it starts receding it is prashman, the other parameter is reading of pulse where bounding will be maximum under the third finger i.e. in ring finger. More details will go very technical i think in nut shell this satisfies your question.
