How to manage gut discomfort, bloating, and other symptoms of irritable bowel syndrome?

Hi doctor,

I have had an undiagnosed chronic condition for at least 27 years, having no success getting help. The symptoms are gut discomfort (inflammation), bloating, rheumatic stiffness, crackling of joints head to toe, and general malaise. However, I recently made an amazing and positive discovery: I have no symptoms if I set the alarm and use mouthwash before my normal wake-up time. I am extremely happy about this, but ultimately I would like a diagnosis and a permanent remedy. I have read on the internet that ectopic colonization of oral bacteria in the intestine drives TH1 cell induction and inflammation. It is not easy to get help where I live. I have to wait three months to see a gastro intestinal doctor. I would love to hear any suggestions from an expert. I would like to know if the average gastrointestinal doctor will know the condition.

Thank you very much.
