Your line of thinking is correct. The body type picture becomes blurry, once imbalances begin to acrue. A vata type, who is constipated, experiences backlushing of waste, which in turn affects bile secretions (Pitta), and eventually dislodges excessive Kapha (fluids and mucus)in the stomach and chest, causing stomach, chest, nost, sinus congestion. So, the original Vata type suffers from superimposed Pitta and Kapha aggrevations. Cleansing the ducts and channels of circulation and elimination, e.g. liver bile ducts, Gi-tract, kidneys , blood and lymph vessels, etc., will help reveal the original constiution, and natural instinct of what is beneficial for it. As the natural laws of the body and the environment are once again in charge, the need to figure it all out will be gone, and carefree freedom will replace the worry and concern. As it is with everything, instead of seeing one's health difficulties as problems, by seeing them as opportunities and blessings in disguise, the process of regaining health can be a wondrous and gratifying experience. Whenever you cannot figure out something, just let it rest for a while and you will be guided to what you need to do next. Worrying over things prevents that from happening.
