thank-you. for a long time now, I have been passing motion very often, sometimes, 2 to 3 times a day..... colour ranges from yellow to dark, sometimes with a strong metallic or rusty smell, and sometimes with particles looking like small chunks of undigested food....... stools are sometimes soft, sometimes floating, sometimes normal, sometimes like diarrhea...... I started noticing the stools after I have had allergy on my fingers (dry, broken and bleed when I do washing) and was given medication which made me vomit once and a second medical opinion gave me omeprazol which made my stomach worse, so that I stopped all medication and start doing research on my own for some answers.....am concerned I might have pancreatic problem as the doctor suspected and gave me the omeprazol.....my worst fear is cancer. what is causing me all those problems, please.....
