- I am 82. I had bowel cancer just over a year ago and hopefully it was successfully removed. No further treatment was needed just follow ups for 5 years. I am constantly nervous about my bowel habits. They fluctuate so much. I get lots of diarrhea which makes me feel quite sick and with this I get a great deal of gas which is very embarrassing and extremely smelly.. I have little control over this. I am a pescatarian and I eat a very healthy diet with plenty of veges. I walk about 2 miles a day with my dog and carry no extra weight. I am now told that I am pre diabetic which has added to knowing what to eat! I am certainly not overweight so it must be genetic. My BMI is in the low category. I get invited out a lot for lunches etc and this makes me so nervous as to what I should eat. I know rich food is a no no but most of the time I have no idea what will spark things off. Is taking Imodium daily a good idea? Any advise would be gratefully received. Many Thanks.
