A single episode of thrush is common and simple to treat. Four or more episodes a year is a different problem requiring a different approach, and repeating single-dose treatment is rarely enough.
Why recurrence happens. First and most commonly, it was never confirmed to be thrush at all — itching and discharge have several causes, so a swab is the logical first step rather than the last resort. Second, poorly controlled blood sugar, which is frequently overlooked. Third, repeated antibiotic courses, which destroy the bacteria that naturally keep yeast in check.

What changes for recurrent cases: a longer initial treatment course followed by intermittent maintenance dosing over several months, combined with addressing the underlying trigger. Breathable clothing genuinely matters in Bangkok's heat and humidity, and stopping douching or antiseptic washes is important — they remove the protective bacteria and make the next episode more likely, not less.
