In daily life, many women often complain that they are “so tired that they have back pain and can’t even straighten their backs. Women’s waists seem to be more fragile than men’s, especially during menstruation, pregnancy and postpartum, and are more likely to suffer from back pain that affects their lives and work. Here we take stock of several factors that lead to lower back pain. 1, menstruation, pregnancy and other physiological characteristics An important reason why women are prone to lower back pain than men is that women go through special physiological periods such as menstruation, pregnancy and the puerperium. Experts say: some girls also eat cold food such as cold drinks during their periods, which can easily lead to Qi and blood stagnation, the meridians do not work, which in turn leads to dysmenorrhea, and some women do not pay attention to rest during their periods, so they always feel sore at the waist when their periods come. Experts point out that after pregnancy, as pregnancy increases, the uterus slowly increases, the lumbar support force is increasing, the uterine round ligament is relaxed due to prolonged stretching, which will lead to the sacral spinal ligament relaxation, compressing the pelvic nerves and blood vessels, so many mothers-to-be will feel back pain. This back pain usually disappears gradually with the recovery of lumbar muscle strength after delivery. In addition, insufficient intake of nutrients in the diet during pregnancy, resulting in calcium deficiency in pregnant women, can also cause low back pain. 2, lumbar muscle strain Lumbar muscle strain is another possible cause of low back pain in women. Experts point out that maintaining a posture for a long time, such as standing for a long time, carrying heavy objects for a long time, can weaken the lumbar tendons and ligaments stretching ability, local accumulation of excessive lactic acid, so that the normal metabolic activities of the lumbar muscles are inhibited, which can lead to lumbar muscle strain and cause lumbar pain. Generally speaking, the real lumbar muscle strain will change with the climate and labor intensity, sometimes heavy and sometimes light, so it is especially important to pay attention to the combination of work and rest at ordinary times. When the body is overworked, or using abnormal standing, sitting posture, etc., can lead to lumbar muscle strain and cause chronic vague pain in the waist. 3, long-term wear high heels Many women love to wear high heels, experts reminded that although wearing high heels can make the body look more slender, but long-term wear high heels will make the balance of the lower limbs are affected, standing, walking can not be arbitrary, the whole body’s reaction, synergistic ability to decline, but also prone to acute lumbar sprain, resulting in lumbago, bringing great inconvenience to work life. 4, urinary tract infection From the physiological anatomy of the urethra, women’s urethra is short and straight, the urethral orifice is close to the anus, coupled with some physiological reasons, resulting in women have a greater chance of urinary tract infection than men. This urinary infection often leads to swelling and pain in the lower back, and in severe cases the pain radiates along the ureter to the perineum. In addition, urinary stones and kidney stones can also cause back pain, so women must pay attention to maintaining the hygiene of the vulva. 5. Spine and lumbar spine lesions Some women suffering from rheumatism, arthritis and lumbar disc herniation can also cause low back pain due to compression of the spinal cord and nerve roots. Sacroiliac joint sprain is one of the most common causes of lower back pain, women’s late pregnancy endocrine influence can make the ligaments relaxed and easy to sprain, and early postpartum for a long time can also cause, mostly manifested as persistent local pain, afraid to bear weight, aggravated by activities, turning over difficulties. 6, osteoporosis Osteoporosis is the most common cause of low back pain in middle-aged and elderly women. Especially after menopause in women, due to the decrease in the amount of bone in the spine, the reduction of the weight-bearing capacity of the spine, the body in the weight-bearing and even in walking will appear low back pain. Therefore, women should usually pay attention to calcium, especially in the 20-30 years of age, more calcium, because this is the best period of women’s life calcium storage. 7, uterine, adnexal and other diseases Experts point out that pelvic inflammatory disease is one of the most common causes of low back pain in women, which is characterized by three major symptoms: low back pain, lower abdominal paroxysmal pain, and increased leucorrhea. When the inflammatory exudate increases resulting in pelvic adhesions, it can lead to low back pain, which seriously affects the life of patients. Back pain can also result when the uterus is posteriorly curved or tilted backwards, when the ligaments are excessively stretched and some nerves are compressed. Experts say that this condition mostly occurs after frequent abortions, multiple births or other uterine surgeries. In addition, prolapse, prolapse or high adhesion of the uterus to the abdominal cavity can also stretch the ligaments and cause the occurrence of lumbago. The pulling of the peritoneum by pelvic tumors can also cause low back pain. “Pelvic tumors are mostly seen in middle-aged women, such as uterine fibroids, cervical cancer, ovarian cysts, etc. Commonly, lumbago occurs due to tumor compression of nerves or cancer cells infiltrating pelvic connective tissue.” 8, abnormal birth control ring Abnormal birth control ring includes the type of birth control ring does not match with the uterine cavity, the elasticity of the birth control ring is too large or the position of the birth control ring is abnormal. Inappropriate birth control ring embedded in the uterine cavity, stimulating the uterine wall, can reflexively cause back pain. In this case, the IUD can be removed and replaced. Experts remind: from the perspective of traditional Chinese medicine, too much childbirth, too many abortions and indiscriminate intercourse can cause kidney damage and cause back pain. Long-term feeling of cold and dampness can also block the meridians and lead to poor blood circulation and lumbago.
