Premenstrual dizziness

If you experience dizziness before your period but have no other symptoms, you don't need to worry too much. It may be that your physical fitness is relatively poor. In that case, it is best to supplement yourself with more nutrients to improve your physical fitness. However, if other adverse reactions occur, you should pay attention. At this time, it may be irregular menstruation, which can only be regulated by taking some medication.

Generally there are no special symptoms, but sometimes there may be general discomfort, fatigue, breast pain, swelling of hands and feet, soreness and heaviness in the lower abdomen and back, etc. There may also be constipation, diarrhea (prostaglandin effect), frequent urination and poor appetite. Some patients experience symptoms such as headache, insomnia, palpitations, depression or irritability, which usually disappear naturally after menstruation.

The relationship between the changes in blood hormones during a normal menstrual cycle and the ovaries and endometrium is as follows: After the corpus luteum atrophies in the previous menstrual cycle, the secretion of estrogen and progesterone decreases, relieving the inhibition of the hypothalamus and pituitary gland. Gonadotropin-releasing hormone produced by the hypothalamus enters the anterior pituitary through the pituitary portal vein system, promoting the secretion and release of follicle-stimulating hormone and luteinizing hormone. Under the synergistic action of follicle-stimulating hormone and luteinizing hormone, the follicles in the ovaries gradually develop and mature, and produce estrogen, causing proliferative changes in the endometrium. After the follicles mature, the first peak of estrogen appears in the body.

The increase in estrogen secretion produces a feedback effect on the hypothalamus and pituitary gland, inhibiting the production of follicle-stimulating hormone, promoting the increase in luteinizing hormone secretion, resulting in a luteinizing hormone peak and triggering ovulation. After ovulation, the corpus luteum is formed and secretes estrogen and progesterone. Under their combined action, the endometrium undergoes typical secretory phase changes. After ovulation, estrogen levels temporarily decrease, followed by a second, lower peak.

The large amount of estrogen and progesterone secreted by the corpus luteum inhibits the hypothalamus and pituitary gland through negative feedback, causing the secretion of follicle-stimulating hormone and luteinizing hormone to decrease, and the corpus luteum begins to atrophy. After the corpus luteum atrophies, the secretion of estrogen and progesterone decreases, the endometrium loses the support of sex hormones, necrosis and shedding occur, and menstruation occurs. After the corpus luteum atrophies, the inhibition on the hypothalamus and pituitary gland is also lifted, causing gonadotropin-releasing hormone to be secreted again, and another menstrual cycle begins.
