”They say that adenomyosis has excessive menstrual flow, but I have very little menstrual flow, but I have pain on my left side, which lasts the longest, and I almost have to rely on painkillers for about 10 days before it stops, which affects my work and mood too much, and I feel like I can’t live without painkillers. Generally, when I introduce the symptoms of adenomyosis, I will talk about these points: dysmenorrhea, heavy menstrual flow, anal swelling, anemia… but I rarely mention “light menstrual flow”. The main reason is that heavy menstruation is one of the most obvious symptoms of adenomyosis. A large percentage of adenomyosis patients have heavy menstrual flow and anemia along with dysmenorrhea. This is mainly because the endometrium invades into the myometrium, the uterus enlarges, and the uterine cavity increases in size, so that every time the menstrual period comes, the endometrium in the myometrium and the uterine cavity will be shed and discharged with the menstrual blood. Then the amount of menstruation will be more. There is also the growth of lesions in the myometrium, which makes the myometrium thicker, the blood supply becomes richer, the endometrium will also thicken, and increased menstruation will also occur. Then what is the reason for the occurrence of low menstrual flow? The first thing to correct is that the amount of menstrual flow is not less if you think it is. Everyone judges the amount of menstruation by an approximate estimate. In fact, the normal amount of menstruation is 20-60ml, only less than 20ml can be called too little. 5ml is almost equivalent to the amount of a sanitary napkin all wet, so using 4 sanitary napkins, almost to 20ml, if you have a period, a sanitary napkin is not used, or a drop appears, then this situation is considered too little. Compared to excessive menstruation, women who come to the clinic in daily life are more likely to worry about low menstrual flow because they think that having a period is a process of detoxification, but this idea is actually incorrect. The main components of menstruation, are endometrial fragments, cervical mucus, broken epithelium of the vagina, anticoagulant substances and blood, which is a precious thing that it should not be lost. There are many reasons for adenomyosis to have low menstrual flow, the main ones are as follows: Firstly, if there is an abnormality in the secretion of female hormones, it will lead to insufficient proliferation of the endometrium to reach the thickness of the menstrual flow, which will result in low menstrual flow. For example, endocrine disorders such as hyperprolactinemia and polycystic ovary syndrome. There are also abnormalities in thyroid function that can cause a decrease in menstrual flow or even amenorrhea. Secondly, uterine adhesions caused by uterine operations are a common cause of reduced menstrual flow. As a result of the uterine operation, the woman’s endometrial basal layer is damaged by the instrument and the shedding of the endometrial lining affects the menstrual flow, so it can also lead to a decrease in menstrual flow. Common uterine operations: abortion, curettage, hysteroscopic surgery. Thirdly, there are also some people who suffer from endometrial tuberculosis as a result. Endometrial tuberculosis is an inflammation of the endometrium caused by Mycobacterium tuberculosis. It destroys the functional layer of the endometrium. As the disease progresses, it may also invade the myometrium, and the endometrium is slowly damaged and slowly decreases, even ending up with amenorrhea In addition, menorrhagia is also associated with imperfect functioning of the pituitary-ovarian axis during adolescence or perimenopause, or with a decline in ovarian function. In addition, excessive weight loss in girls who love beauty, especially dieting and medication, can also lead to reduced menstrual flow or even amenorrhea. The decrease in menstrual flow is also related to emotions, some girls are stressed, nervous and anxious, which can also lead to a decrease in menstrual flow. If you have recently taken oral contraceptives, used a contraceptive ring, or had surgery on your uterus, it can also lead to a decrease in menstrual flow. So there are many reasons for reduced menstrual flow, and to identify the cause, it is recommended to get a hormone 6 test, ultrasound, thyroid function, and if necessary, a hysteroscopy. If it is endocrine, regulate the endocrine, if it is related to birth control pills, then you can consider using condoms instead… If after a series of examinations the above abnormalities are not found, do not be too nervous, in fact, the low menstrual flow does not have a great impact on the body, and the amount of menstrual flow, generally does not affect pregnancy, so generally do not need special treatment.
