Final answer:
Dysfunctional uterine bleeding is true as it refers to abnormal uterine bleeding and can lead to iron deficiency anemia, especially in individuals with a restrictive diet like veganism.
Step-by-step explanation:
The statement “Dysfunctional uterine bleeding (DUB) is excessive hemorrhage during menstruation” is True. Dysfunctional uterine bleeding is a condition characterized by abnormal.
Irregular uterine bleeding that is not related to any underlying structural abnormalities. This condition can lead to significant blood loss and anemia.
Especially if a person has a dietary restriction that may limit the intake of certain nutrients, such as iron, which is important for blood production.
In the case of the young woman following a strict vegan diet and experiencing heavy menstrual bleeding, she is at risk for developing iron deficiency anemia due to the loss of blood during menstruation without sufficient dietary iron to compensate.
As for hormonal regulation, each phase of the menstrual cycle is controlled by various hormones such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, and progesterone.
Endometriosis, which is the growth of endometrial-like tissue outside the uterus, may increase a woman's risk of infertility due to the inflammation and scarring it causes which can disrupt the function of the ovaries, fallopian tubes, and the implantation of the embryo.
Regarding the woman who experiences minor bleeding and cramping 3 weeks after her last period, this might be implantation bleeding, which occurs when a fertilized egg attaches to the lining of the uterus. Another possibility could be an irregular menstrual cycle.
