My wife is 52 yrs. For the past ten years she is taking tablets for Type 2 diabetes, blood pressure, vertigo and depression. She reached menopause state 2 years back. She is complaining that few tablets such as gluconorm G1, neurobion forte, menopace ISO that she consumes is being passes out intact (unchanged and unabsorbed) in the faeces for past 2 yrs. Further she says that some cooked vegetables like greens, carrot passes out without digestion and found appeared in faeces .She feels that there is no use of consuming these tablets/ vegetables and stopped taking it. She breaks down some tablets into pieces and consumes it. Please explain the reason for it. Further I request the ways and means to improve digestion and absorption. Pl suggest medicines to improve digestion and absorption.
