Which of the following conditions might result in menorrhagia?

Menorrhagia, or heavy menstrual bleeding, can be influenced by various medical conditions. Each of the conditions mentioned can contribute to this issue.

Hypothyroidism can lead to hormonal imbalances, particularly affecting menstrual cycles. An underactive thyroid can cause prolonged periods or increased menstrual flow due to insufficient hormone production affecting the health of the endometrium.

Polycystic ovary syndrome (PCOS) also plays a significant role in menorrhagia. This condition is characterized by hormonal imbalances and dysfunctional ovarian activity, which can lead to irregular periods and heavier bleeding.

Uterine fibroids, which are non-cancerous growths in the uterus, are a well-known contributor to heavy menstrual bleeding. They can disrupt normal uterine function and structure, often resulting in increased menstrual flow and prolonged menstruation.

Since all of these conditions – hypothyroidism, PCOS, and uterine fibroids – are capable of causing menorrhagia, it is appropriate to conclude that any of these conditions can result in heavy menstrual bleeding, making “all of the above” the most comprehensive correct answer.
