My Father, who is 82 years old has had very frequent, very small, bowel activity movements. this has been going on for more than 4 week s. I can tell that it is worrying him. Since January (the beginning) He has undergone eye surgery to both eyes and in between those, he had some skin cancer remove from his chest, He says that the fecal matter is very soft, and no bigger than the end of his pinky finger, and has to go at least five time through the day and he wakes up through the night hours to get up and use the toilet. As little as he goes each time, he does not think that it is emptying him out the way it should. Do you think we need to get my dad in for a colonoscopy test. Do you think this is cause for alarm?
