Re: SIBO or parasite?
Every case you should treat differently, but it seems I have similar symptoms to you, all of them, except the orange color and asthma. For me, I have not found yet what it is. Although I have also pushed myself and was under stress for extended periods, which might be the cause even if I don't see that yet.
Can you try a diet with less meat? (perhaps once a week or remove completely) it felt easier for me to cut on
Sugar along with cutting the meat than without removing it. Or already on that?
Perhaps strange, but can you also be more mindful on chewing the food?
And the 'usual': move an hour a day, sunlight 30min, reduce self-induced stressors ("I should do... and.... and...."), proper nose-breathing, eat good liver foods, fixed bedtime and dinner routines.
Also some pictures of stool wouldn't hurt if that's possible. Along with frequency.
