There are a number of possible causes.
First, any time the balance is changing within the gut, there is likely to be some fighting as they rebalance.
Second, When some bacteria die, it is possible that some foods, etc., won't be digested quite the same, so may take a bit to have the bacteria, etc., necessary to repopulate.
Third, there may be some hard to digest products being cleaned out of the body that is causing the bloating as it works through.
It will be impossible to eliminate totally this bloating as things are killed within. I think we all go through it at some level when killing and healing.
