Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? Does excessive exercise cause the endometrium to shed?Doctor's answer:
The shedding of the endometrium is generally caused by the failure of the egg to be fertilized after ovulation, leading to the atrophy of the corpus luteum. The average lifespan of the corpus luteum is about 14 days. After the corpus luteum atrophies, the levels of estrogen and progesterone in the ovaries drop rapidly, causing the endometrium to lose support and shrink. Due to ischemia and necrosis, the endometrium then sheds, resulting in vaginal bleeding, which is commonly referred to as menstruation.The first three months of pregnancy are a critical period for embryonic development. Medication use during this time must be cautious. If a pregnant woman catches a cold, she can appropriately take Banlangen, which generally has little impact and does not need to be a cause for concern.
