Ah, thank you for these important clarifications!
May I ask: how "quick" is "fairly quick" mucusa replacement? Like days/weeks/months? Anything less than a year at this point I consider quick, LOL!
The intestine is the most highly regenerative organ in the human body, regenerating its lining, called the epithelium, every five to seven days.
But this is only the lining. In the colon there is also concern for the cells under the lining. It is less clear how fast crypt cells regenerate. Muscle tissue may also have permanent scaring.
Hopefully once inflammation is gone, the normally quick regeneration of the colon would kick in.
