Any disturbance to any function also disturbs the other functions. For example, when a person’s digestion is not proper, he may not have a proper bowel movement, which will make him feel heavy, and bloated, which could then precipitate a headache, it could disturb his sleep which in turn could aggravate his digestive process and so on creating vicious circles leading to more and more chronic diseases. The body of a healthy person in the meanwhile tries to re-establish the harmony with some support from the person. Like, if the person doesn’t over feed himself on feeling heavy, the body gets over the initial problem and thereby prevents the chain of events. When the harmony is upset in a number of functions and particularly with growing age, the ability of the body to bounce back to normalcy gets hampered. With more and more functions getting upset the problems get into more complications and become irreversible or not fully curable.
