Brief Answer:
You seem to have 2 different problems
Detailed Answer:
Hello XXXXXXX
I have read your query. It seems like you have two different problems.
One is with the urination or passing urine. The other is the bloated feeling in your stomach. The problems are not related to each other.
Your problem of passing urine more often is concerning. Before you proceed with the investigations, I would like to know if you got a urine routine test done. If yes, please upload the report on the right side of this query page.
Initially, you do not need
colonoscopy, abdominal x ray or
upper endoscopy as suggested. Firstly, a urine routine and microscopy is what is required. It seems like a possible
urinary tract infection ascending into the pelvis.
Do you have a lower
abdominal pain just above the pubis? You could get a plain x-ray of the abdomen done.
For the bloated feeling in your stomach, upper endoscopy is suggested. I would suggest you to take simple effective antacids like Capsule
Omeprazole 20mg once daily early in the morning on empty stomach for a few weeks. The medicine is available over the counter, and it would take care of
gastritis and the
bloating sensation. If you do not respond to this treatment, then you can think about getting Upper endoscopy done.
It could be stress related, as you say. It does not sound like a STD to me.
Give me clarifications about the urination problem and the bloating problem, to help you much better.
Regards,
