Hello Boban: Yes it is certainly possible what you are experiencing is the result of anxiety.

But it can also be all too easy for doctors to dismiss a person's condition by chalking it up to anxiety... especially if they know anxiety is something you struggle with.
You know how much discomfort you are in.

If this is something that is troublesome for you, my suggestion is to either go back to see the doctor you've been seeing again, or perhaps consider getting a second opinion, if you can, possibly from a doctor who specializes in problems related to the digestive system. I wish you well...
