For many people, menstrual blood may just be seen as the red fluid that flows from the vagina during menstruation. However, menstrual blood color can change throughout the cycle, and brown menstrual blood is one of the most common color variations. It can be concerning to see brown menstrual blood, but it is usually not a cause for alarm. Here, we explore the causes of brown menstrual blood.
Understanding Menstrual Blood Color Changes
The color of menstrual blood can vary from bright red to dark brown depending on factors such as the amount of blood, how long it has been in the uterus, and the presence of other substances such as cervical mucus. Typically, menstrual blood starts off as bright red and becomes darker towards the end of the period.
It is common to experience brown menstrual blood at the beginning or end of your period. This is because brown menstrual blood is older than red blood and has had time to oxidize, or react with oxygen in the air, causing it to turn brown. Brown menstrual blood can also be caused by a slow flow of blood that takes longer to leave the uterus and is exposed to oxygen for a longer period.
Uncovering the Causes of Brown Menstrual Blood
Brown menstrual blood can also be caused by other factors such as hormonal imbalances or infections. Hormonal imbalances, such as those caused by polycystic ovary syndrome (PCOS), can affect menstrual blood color and flow. Infections such as bacterial vaginosis or STDs can cause inflammation or irritation in the uterus, leading to changes in menstrual blood color and texture.
In some cases, brown menstrual blood can also be a sign of an underlying medical condition such as endometriosis or fibroids. Endometriosis occurs when the lining of the uterus grows outside of the uterus, and fibroids are non-cancerous growths in the uterus. Both conditions can cause changes in menstrual blood color and flow, as well as other symptoms such as pelvic pain.
While brown menstrual blood can be a normal variation, it is important to pay attention to any other symptoms you may experience, such as pain or changes in menstrual flow. If you are concerned about your menstrual blood color or experience other symptoms, it is important to speak with your healthcare provider. Keeping track of your menstrual cycle and any changes that occur can also help your healthcare provider diagnose any underlying conditions.
