I have been having loose stools usually after meals and this happened after I started travelling and moved to and fro or else I used to have normal bowels. Now am getting paranoid by searching on net that loose stools can also be caused by some seeds and I know that's not likely to happen as I have never been in any kind of sexual relationship and I also know it can be spread through infected person's blood and stuff. But nothing like that happened though. Could it be because of any digestive problem or any chances of having stds? Can saliva also lead to any std that can cause loose stools? I am really getting emotionally stressed out and worried now by reading all these stuff through net. I need some accurate answers please.
