Why does my stomach feel like I have menstrual pain after spotting?

When women are menstruating, they should pay attention to keeping their abdomen warm and avoid stress. Women will experience abdominal pain, dizziness, decreased resistance and other symptoms when they are menstruating. Some women will also experience abdominal pain after menstruation, just like the pain during menstruation. Is this normal? Why does my stomach feel like I have menstrual pain after spotting? Let’s take a look at it next.

1. Why does my stomach feel like I have menstrual pain after spotting?

If you experience vaginal bleeding and abdominal pain after your period is over, it may be caused by pelvic inflammatory disease or endocrine disorders. It is recommended that you go to the hospital for an ultrasound and six hormone tests. After the cause is confirmed, symptomatic treatment can be given.

2. Menstruation

In order to explain this issue, we must first understand the structure and physiological functions of female reproductive organs.

The female internal reproductive organs consist of the ovaries, uterus, and fallopian tubes. The main function of the ovaries is to produce eggs and synthesize ovarian hormones, while the uterus and fallopian tubes are reproductive organs. The ovaries contain hundreds of thousands of follicles, each of which contains one egg.

Before puberty, the follicles are essentially non-functional. During puberty, under the action of gonadotropin from the anterior pituitary gland, immature follicles gradually develop and synthesize estrogen. When the follicle matures and ovulates, the follicle wall collapses, the cells become larger and yellower, and are called the corpus luteum. It synthesizes estrogen and produces progesterone.

As the ovaries change, the endometrium is also affected and undergoes corresponding cyclical changes. Estrogen causes the endometrium to thicken, the endometrial cells to increase in number and size, and the arterioles in the interstitium to become more tortuous and spiral, which is called the proliferative endometrium. After ovulation, due to the combined effects of estrogen and progesterone, the endometrium becomes edematous, the glands produce a large amount of mucus and glycogen, and the thickness of the endometrium increases from 1 mm to 6 mm, which is called the secretory endometrium.

If the egg released at this time is fertilized, the fertilized egg is transported to the uterus through the fallopian tube for development, which is called pregnancy. The pregnancy tissue synthesizes a chorionic gonadotropin, which supports the continued development of the corpus luteum of the ovary. If the egg is not fertilized, the corpus luteum will atrophy and stop secreting estrogen and progesterone about 14 days after ovulation. At this time, the blood vessels in the endometrium contract, the endometrium necrotizes and falls off, causing bleeding and forming menstruation.

Therefore, the length of the menstrual cycle depends on the length of the ovarian cycle, which is generally 21-30 days, but varies from person to person, and may be 23-45 days, or even 3 months or half a year as a cycle. As long as it is regular, it is generally considered normal menstruation.

The bleeding time is generally 3-7 days, and the total amount of bleeding each time is 30-50ml. Some people believe that menstrual volume exceeding 80ml is a pathological condition.

3. Causes

Menstruation is regulated by the interaction between reproductive hormones from the hypothalamus, pituitary gland and ovary. During the menstrual period and proliferation period of the menstrual cycle, the levels of estradiol and progesterone in the blood are very low, thereby weakening or eliminating the negative feedback effect on the pituitary gland and hypothalamus, leading to increased secretion of gonadotropin-releasing hormone by the hypothalamus, which in turn leads to increased secretion of follicle-stimulating hormone and luteinizing hormone by the pituitary gland, thereby promoting follicle development and gradually increasing estrogen secretion. At this time, estrogen stimulates the endometrium to enter the proliferative phase. Luteinizing hormone increases progesterone secretion
