Hi, thanks for using healthcare magic
Usually complete resolution, after using appropriate medication, is within 7 to 10 days after the medication is started. Vancomycin
are the recommended medications with vancomycin having a better rate of response.
It would be expected that her diarrhoea
should have resolved by now if this time has passed.
Approximately 20 % to 27 % of persons with a first time episode with this bacteria can experience are relapse . This relapse occurs 3 days to 3 weeks after treatment has failed.
In this case however the stool cultures would have come back showing the bacteria.
It is possible that her intestinal wall is not yet repaired itself to allow for the absorption of food. If the bacteria is gone, then this healing should occur and she should see a decline in stool frequency soon.
I hope this helps
