Astanga Hrudaya
वृद्धिं मलानां सङ्गाच्च क्षयं चाति विसर्गतः। मलोचितत्वाद्देहस्य क्षयो वृद्धेस्तु पीडनः॥२५॥
The increase of Malas is observed by their non-elimination (too much of waste product accumulation leading to obstruction) and their decrease by too much of elimination in little quantities. Body being accustomed to accumulation of waste products (in intestines and bladder) , the decrease of waste product formation is more troublesome than their increase.
