<s>[INST] Hi Doct, I had gastrocopy and Colonscopy last friday , after that test i found my lower was swalled a bit and it's still swallen( big)..........it's about 5 days now, it's not painfull but it's bit red.............any suggestion would be very helpfull , thank you [/INST] Hi,Thanks for writing in HCM.As long as you are passing flatus and stools smoothly you need not worry. It is usually due to the gas which is pumped in while the procedure is being performed which induces the distension. It is a self remitting after effect. In the mean time avoid eating fat rich ,flatulent food products.Regards </s>
