Hi.
Thanks for your query.
Noted the history and understood the concerns.
Diverticulitis is known to recur over time if the precipitating causes are present like
constipation, food habits, lowered immunity due to any causes like diabetes and so on.
Hence it looks that you have some precipitating causes which should be found and treated or corrected to get least recurrence.
If these measures fail then the whole colon may need to be removed.
Molds in office may not be related to the present problems.
I would advise you the following:
Get a consultation of a Surgical Gastrointestinal Specialist for clinical evaluation, examination and investigations like CT scan of abdomen,
colonoscopy and decide about further management.
Till then take antibiotic,
metronidazole, probiotic, ,multivitamins and minerals.
Get anemia and
hypoproteinemia corrected.
