Having ibs from past 3-7 days, today having bright blood after stool also lost 1 kg in 3/4 days. If someone look over it kindly tell me what are causing all these stuff. On 10th of may I hv eaten meat and then on15th of may I ate stale samosa and on that day after some hours I go to poop I got little blood then next day I got loose motion after medication loose motion stopped but then after when I take meal after 2 hours I need to poop. Also having gas which doesn't pass. To stop loose motion I have taken lopamide tablet, fagyl 400.
