Toxic Shock Syndrome (TSS) is a rare but serious condition that often causes anxiety among many people.. Despite its rarity—with only 0.03-0.50 cases per 100,000 menstruators—understanding TSS is crucial for period health.

TSS is caused by specific strains of Staphylococcus aureus or Group A Streptococci bacteria. These bacteria are present in 10-20% of menstruators, but only a fraction carry strains capable of producing the TSS-1 toxin.
Four main risk factors contribute to TSS:
Presence of staph or strep in the vagina
Altered vaginal pH (blood raises pH during menstruation)
Oxygen introduction (via tampons, menstrual cups, or menstrual discs)
An entry point to the bloodstream (cuts or tears in vaginal tissue)
All menstruators are at risk of TSS, regardless of product choice. Key symptoms include sudden high fever, muscle aches, dizziness, and a sunburn-like rash.
To protect yourself:
Maintain proper hygiene for menstrual products
Take breaks from internal products if experiencing discomfort or infections
Be aware of symptoms and seek immediate medical attention if concerned
Remember, knowledge is power. Understanding TSS helps manage your period safely without unnecessary fear.
