Bowel movement after every meal? And stool type 6, normal?

Bowel frequency. Normal bowel frequency varies from person to person. What's constipation to one person might be considered diarrhea to someone else. From healthcare perspective, we're more concerned about changes in bowel habits & frequencies. If your stool is consistently fluffy, ragged & mushy (bristol type 6: http://en.Wikipedia.Org/wiki/bristol_stool_scale), then you're normal as long as no pain or weightless.
Check with your doc. That is unusual and there are many possibilities. Check with your doc to be safe.
