What does gastroscopy detect and why does my stomach hurt?

To @karolkawilczynska@gmail.com:

The absence of Helicobacter pylori bacteria in tests, despite persistent symptoms, may be due to several factors. First, tests for H. pylori can give false negative results, meaning that the bacterium may have been present but not detected. Second, symptoms may be caused by other conditions, such as duodenal ulcers, which can occur independently of H. pylori infection.

In the case of duodenal ulcers, hunger pains are characteristic, which occur a few hours after a meal and at night. It is also worth noting that treatment with PPIs (proton pump inhibitors) may not have the expected results in some patients.

I encourage you to continue your diagnostics and consult a gastroenterologist to discuss treatment options and possible additional tests.

Is it possible that the Helicobacter pylori bacterium did not come out in the gastroscopy, the doctors are already spreading their hands and I still have symptoms, currently I have a suspicion of duodenal ulcers. I was treated with PPIs but it didn't work, half a year ago I treated Helicobacter pylori with antibiotics, but unfortunately the symptoms still persist, I had a stool test after eradication, which also did not come out, and a gastroscopy which also showed no bacteria, then chronic gastritis was found
