If you're experiencing an improvement, great. It seems reasonable that your gut issues (if nothing else) could be improved by addressing the gut biome.

Since you've had some luck with traditional medicines, I can share my $0.02 about the traditional system I'm somewhat familiar with. In traditional Indian folk medicine, the focus for practically everything seems to revolve around improving gut health. It's a common belief that tongue health is a reflection of gut health, so for example a coated tongue suggests a sluggish digestive system, and the physician will seek to address that before anything else. A lot of treatments also include required dietary changes (like avoiding certain vegetables).
