Final answer:
The biggest risk of douching is disrupting the natural chemistry of the vagina, which can lead to increased risk of infections due to the disturbance of healthy microorganisms. The American College of Obstetricians and Gynecologists recommends against douching for maintaining vaginal health. Correct option is A.
Step-by-step explanation:
The biggest risk associated with douching is changing the natural chemistry of the vagina. Douching disrupts the balance of healthy microorganisms that are essential for protecting the vagina against infections. The vagina is protected by beneficial bacterial flora, predominantly Lactobacillus, which maintains an acidic pH to prevent the survival of potential pathogens. The American College of Obstetricians and Gynecologists advises against douching to preserve the vagina's natural defenses.
Engaging in practices such as wearing loose cotton underwear and avoiding perfumed soaps and hygiene products can help maintain the vaginal microbiota. Avoiding douching is crucial in preventing vaginitis and ensuring that the vagina’s natural cleaning mechanisms function optimally. The use of douching products can also introduce disruptions that increase the risk of infections and irritation, which is the paramount concern when considering vaginal health.
