Talk to Gastroenterologist on Pylori And Its Post Symptoms

Hi i have being diagnosed with pylori last year and have been treated with antibiotics for the same. However since last year after the treatment i have been facing excessive fatigue, brain fog, lack of interest in things and work along with pain in right abdominal area. Can it be due to leaky gut caused by pylori or can u guide me which doctor to see for leaky gut?
