Getting yeast infections over and over usually means there is an underlying factor allowing yeast to grow too easily. In many people, this is related to changes in hormones, blood sugar levels, immune response, or repeated disruption of the normal vaginal balance. It is common for these infections to come back even after proper treatment.
Research shows that frequent yeast infections can be linked to recent antibiotic use, uncontrolled diabetes, pregnancy, high estrogen levels from birth control, or conditions that weaken immune defenses. Some people also have a natural tendency to react more strongly to yeast, making symptoms return even when yeast levels are low. In certain cases, the yeast can form protective layers that make it harder to fully eliminate.
These infections are not usually sexually transmitted, but irritation, stress, or repeated treatments without confirmation of the cause can worsen the cycle. Symptoms that return soon after treatment may mean the yeast type is different or resistant to common medications.
If infections keep coming back, it is important not to self-treat repeatedly. A gynecologist can confirm the diagnosis, identify the yeast type, and recommend a safer long-term plan tailored to the cause.
