What is the reason for less menstrual flow and bright red color?

Patient's question:

No

Doctor's answer:

There are many reasons that can cause a decrease in menstrual flow, such as endocrine disorders, gynecological inflammation, changes in the mental environment, anemia, etc. Additionally, it may be due to the condition of the endometrium itself, such as endometrial tuberculosis causing endometrial lesions or artificial abortion, scraping the uterine cavity leading to thinning of the endometrium, etc.
