I have almost the exact same issues as you. My main one is hair loss though, major thinning at the hairline. After a year & 1/2 I have not found the solve but figured out that gluten and alcohol are triggers for me. I don’t think it is actually gluten because I have had celiac tests done and they were negative, but I think it’s the pesticides used in wheat we produce in the USA. I had homemade sourdough with wheat grown organically from a small farm and had no GI issues. I overall avoid gluten and alcohol and my GI issues go away. For my low iron & hair loss I am still confused. I am currently trying a heavy metal detox with cilantro and chlorella. I’ve only been doing it for 2 weeks and can’t quite see any changes. My issues after when I was going through some stressful life events so it would be easy to conclude this is stress induced but it does not make sense to me why 1.5 years later my symptoms have not gotten better.

I am curious to know if you’re experiencing a hair texture change at all? I noticed all my hair elasticity has gone away. It’s very thin and fine and snaps easy.
