Menstrual blood often has a mild smell. This is normal and happens because blood, uterine tissue and vaginal bacteria mix during a period. The smell may change slightly over the course of your period.
01 Why does menstrual blood have an odour?
The way menstrual blood smells depends on several factors, such as the natural pH of the vagina, the presence of bacteria, and the amount of time the blood stays in contact with air. Infections and other health issues are not diagnosed by smell alone but if you notice a strong or unpleasant smell, particularly if accompanied by unusual discharge, itching, soreness or pelvic pain, may be a sign of an infection and should be assessed by a healthcare professional.
02 Is it normal for menstrual blood to have a metallic smell?
Yes, a metallic odour, resulting from the presence of iron in blood, is typical and should not cause concern. Similarly, a mild acidic smell is the result of the natural environment of the vagina, where the pH level in a healthy state range between 3.8 and 4.5.A mild change in odour during your period is common. Some people notice an earthy or stronger smell during menstruation because blood and uterine tissue break down after leaving the body. This is usually norma, however, a strong unpleasant smell, particularly if it is accompanied by unusual discharge, itching or irritation, should be checked by a healthcare professional.
03 Is it possible to eliminate the smell of menstruation?
It is worth noting that some women may experience a distinctive smell during menstruation due to individual body characteristics. Regular, but not excessive, washing of the intimate area, once daily using warm water, as well as frequent changes of period pads and other period produces can, are essential measures to help reduce odour and ensure comfort during menstruation. Period pads should generally be changed every 4-6 hours, or sooner if they are saturated if you have a heavy flow.
However, excessive use of products designed for the genital area such as deodorants or sprays should be avoided, as they can irritate and disrupt the natural bacterial balance of the vagina. The normal balance of bacteria in the vagina protects against microbial proliferation and the formation of unpleasant odours. Excessive chemicals can lead to infections, such as bacterial vaginitis or yeast infections, which further compound the problem.
If, despite good hygiene, the odour persists or other worrying symptoms such as pain or burning occur, it is necessary to consult a doctor.
