How does Yogurt work?
Yogurt contains bacteria which may help restore the normal bacteria in the digestive tract and vagina. This might help treat diarrhea and vaginal infections.
Are there safety concerns?
Yogurt is likely safe for most adults when taken by mouth. Yogurt is possibly safe when used in the vagina. There aren't many reported side effects, but there have been cases of people getting sick from yogurt contaminated with disease-causing bacteria. Be careful to choose yogurt that has been prepared and stored properly. There is some concern that people with weakened immune systems, such as people with HIV/AIDS or organ transplant recipients, might have an overgrowth of the live bacteria in yogurt, such as lactobacillus, from eating large amounts of yogurt. Lactobacillus in yogurt has caused disease (rarely) in people with weakened immune systems. To be on the safe side, if you have a weakened immune system, avoid eating large amounts of yogurt that contain live bacteria for prolonged periods of time without advice from your healthcare professional.
