Early pregnancy is an important period for embryonic growth and development, and pregnant women often have various early pregnancy reactions at this stage, such as lumbar acidity, nausea, vomiting, drowsiness and weakness, so lumbar acidity may be caused by normal physiological factors, or it may be due to disease factors. Common causes and treatments 1. Physiological factors: as the fetus grows, the body’s center of gravity shifts forward, thus increasing the burden on the lumbar and caudal vertebrae; when the body’s water diverts to the pelvic veins, it may make the nutrient supply to the lumbar nerves and spine insufficient; hormonal changes during pregnancy make the joints loose, etc., which can lead to lumbar soreness. The symptoms of back pain can be relieved to a large extent by improving daily habits, such as not standing for too long, using a belly brace when walking or lifting heavy objects for a long time, supporting the waist with both hands to reduce the load on the waist when changing the posture, and not wearing high heels to reduce the burden on the spine. In addition, massage and hot compresses can be used to relieve the symptoms of lumbago. 2. Disease factors: If the lumbago is severe and unbearable, and accompanied by a small amount of vaginal bleeding, mild lower abdominal pain or low back pain, you need to consider the possibility of pre-eclampsia. At this time, you should go to the hospital in time, and immediately carry out treatment after clear diagnosis, such as fetal preservation treatment, etc. Secondly, pregnant women should rest in bed more often and should not overexert themselves. In addition, pregnant women should also exclude the possibility of lumbar muscle strain and lumbar spine disease. Attention should be paid to rest, regular work and rest, ensure sufficient sleep, appropriate exercise, pay attention to warmth, once you find any discomfort, go to the hospital in time for regular review.
