Why menstrual blood might have a bad odour

1. Menstrual products stay too long

Menstrual products can produce unpleasant scents if kept in or on for a long time. You should change them every eight hours, twelve hours, or twelve hours, depending on your preference. This can eliminate undesirable smells and lower the risk of urinary tract infections, sexually transmitted diseases, and toxic shock syndrome (a rare, life-threatening complication of certain bacterial infections).

2. Excess sweating

Excessive sweating during menstruation can also result in an mixture of salt, fat, and bacteria in the vagina. To treat this, gently wash your vulva with warm water and mild soap, then apply a soft cleanser free of scents. It is crucial to realise that STIs do not necessarily accompany an aroma or visible symptoms.

3. Changes in the vaginal microbiome

The menstrual cycle can produce unusual smells due to the combination of vaginal mucus and endometrial cells in the blood.

If your vaginal microbiome changes include douching, smoking, hormonal changes caused by pregnancy or menopause, and sexually transmitted infections.

To treat this, practice appropriate vaginal hygiene like bathing your vulva with warm water every day and after sex, wearing breathable cotton pants, washing new pants before use, and avoiding douching and scratching.
