The menstrual blood has become redder than before, a bit dark? What should I do?

Patient's question:

Last month, I ate a lot of spicy food. This month, my menstrual blood has turned black. Is it due to internal heat? What should I eat to replenish? What foods should I avoid? Do I need to see a doctor? Thank you

Doctor's answer:

Menstruation can be judged based on a woman's usual condition. If a woman has a normal menstrual cycle and normal ovarian function, it means that a small amount of menstrual flow does not affect her body, and this can be considered normal. Some women may also worry whether blood clots in their menstrual blood indicate a disease. In fact, some blood clots are normal in menstruation, as they are the result of the shedding endometrium being expelled with the menstrual blood, and there is no need to worry.
