What is the situation when menstruation is black?

Patient's question:

I am 25 years old, male. When my period comes, everything else is fine, mainly the blood is black and the amount is less. Please ask what are the reasons for the black menstrual blood

Doctor's answer:

Dark menstrual flow with a small amount is caused by menstrual disorders, which may be due to organic inflammation, medication side effects, or dysfunction of the nervous and endocrine system. These factors can lead to such symptoms, so it is still recommended that you undergo a thorough examination promptly to identify the cause and receive appropriate treatment. Patients should develop a regular lifestyle with good sleep habits, adhere to treatment, maintain a light diet, and engage in aerobic exercise. This can help boost the immune system and reduce the risk of illness.
