### input:
Doctors found H pylori in my blood work, but havent gotten the results back if it is currently active. I feel so sick every time I eat anything, when I say sick I mean that I feel extremely full, nauseous, and I feel a constant need to burp. Ive lost about 10 pounds and I dont know what else to do. I keep reading that H pylori is assosciated with stomach pain and vomiting, both of which I dont have. Also, I dont have any ulcers I was already screened and all of my other blood work is good. This has been going on for about 3 months now. The first 2 months were the worst. I did not get my period for the whole first month, and then when it came I felt extremely sick prior, but during my period and when it passed I felt amazing. Now, this month of October I didnt get my period again for a whole month and its Nov. 6 and still dont have it. Im starting to feel worse again so maybe it is coming, and I cannot wait because I know I will feel better when it comes. What could this be? Could it be from the H Pylori? Or is it coincidental that they found that while trying to figure out what else is wrong?

Hi. H.pylori can induce an inflammation of the stomach lining called gastritis which can cause nausea bloating abdominal pain etc. To find out if it is an active infection you may get a Urea breath test done. This is a simple test where you just breathe into a plastic tube. The other test that can detect active infection is H.pylori stool antigen test. If H.pylori is detected by any of the above tests you have to take a course of treatment to eradicate H.pylori. Treatment is by the triple therapy method or qua Chat Doctor.  Your doctor may prescribe this if your H.pylori is active. The H.pylori blood test or as we say serum test is not very specific because it detects old infection with H.pylori and therefore current activity cannot be properly analyzed. Worldwide the H.pylori breath test is regarded as the test with the best sensitivity and specificity to detect active disease. This is a non-invasive test. Rarely endoscopic tests and biopsy of stomach tissue is done to exclude other problems and to confirm H.pylori. As the first step please get a H.pylori breath test or stool antigen test done. If they are positive please proceed to take H.pylori treatment which is quite effective. Best regards
