What is a tampon?

Tampon is a mass of absorbent material that is used to absorb the menstrual fluid during menstruation. Tampon is worn inside the vagina, where it absorbs the menstrual fluid right after it is released from the uterus.

Tampons have different absorbing capacities which are depicted clearly as its absorbency rating on the packet. You should use a tampon with the lowest absorbency rating that is enough to meet your requirements. A tampon should not be left inside the vagina for more than 6 hours because prolonged use of a tampon can cause a rare but potentially fatal illness called Toxic Shock Syndrome (TSS).
