What is Toxic Shock Syndrome?

Toxic Shock Syndrome (or TSS) is a rare but potentially life-threatening illness. Researchers believe it is caused by an infection resulting from certain staph and strep bacteria that often exist even in a healthy woman’s vagina. The exact process is unknown, but it’s thought that these bacteria multiply in the presence of a bloodsoaked tampon. It’s actually not the bacteria that cause the TSS directly. Rather, it’s the toxins that the bacteria produce that do the harm.

It’s important to note that staph bacteria are very common.We all have them on our skin and inside our noses. Usually they are harmless, but if they gain access to the bloodstream or deeper tissue, they can cause a serious infection.

For TSS to occur, certain strains of the bacteria have to overpopulate and produce large amounts of toxin. This toxin then has to gain access to the bloodstream. One generally accepted theory is that super-absorbent tampons that are left in the vagina for extended periods of time can encourage growth of the bacteria. And importantly, these super-absorbent tampons can also adhere to the vaginal wall if they are dry and the menstrual flow is light, thereby causing tiny abrasions when removed. These abrasions then provide access to deeper tissue or to the bloodstream for the bacteria and toxins.
