Over the last few months when I eat takeaway or drink soft drinks I get loose bowl motions several times. Should I see a dr?

This sounds like. a overactive "gastrocolic" reflex...(actually a NORMAL reflex when you eat) and this may be do to HOW FAST YOU EAT rather than WHAT you eat! Tryy slowing down a bit and try a healthy diet as well! If this doesn't help check it out with your PCP (Primary Care Physician) Hope this helps! Dr Z.
