Final answer:
The symptoms described are actually symptoms of low estrogen levels. Estrogen is a hormone that regulates several bodily functions, including the menstrual cycle and the health of the reproductive system.
Step-by-step explanation:
The symptoms described, such as hot flashes, mood swings, slowing metabolism, fatigue, and atrophic vaginitis, are actually symptoms of low estrogen levels. Estrogen is a hormone that regulates several bodily functions, including the menstrual cycle and the health of the reproductive system. During menopause, the ovaries produce less estrogen, leading to these symptoms. It's important to note that the decline in progesterone levels during this time can also contribute to some of these symptoms, but the primary cause is a decrease in estrogen.
