The occult pain in the abdomen after pregnancy is mainly related to physiological factors such as uterine ligament pulling and pelvic congestion, but also seen in abnormal pregnancy, gynecological inflammation and other disease conditions, which require timely consultation, ultrasound examination, and then symptomatic treatment after analysis according to the time and degree of pain. Common causes and treatments 1, physiological factors: after pregnancy, the estrogen and progesterone in pregnant women’s bodies will gradually rise, making the ligaments relax, while the growing uterus is also pulling the uterine ligaments, leading to a feeling of hidden pain in the abdomen. Also, when the uterus expands, blood will accumulate in the pelvic or abdominal cavity, which may also cause hidden pain in pregnant women. Usually the physiological factors last for a short time and can be relieved by resting; 2. Disease factors: the pain is mainly caused by conditions such as pre-eclampsia, ectopic pregnancy and gynecological inflammation, which require timely access to the hospital for relevant maternity examinations. In case of pre-eclampsia, it can be manifested as paroxysmal lower abdominal pain or low back pain, which lasts for a long time and cannot be relieved by rest, and can be treated with fetal preservation under the guidance of professional doctors. If the pregnancy is ectopic, it is usually a tubal pregnancy. When the fallopian tube is not ruptured, it can also manifest as lower abdominal pain or distension, which requires timely consultation and treatment by medication or surgery; gynecological inflammation can also cause abdominal pain in pregnant women, which can be treated by improving the relevant pathogenic examination and clarifying the specific pathogenic bacteria. Pregnant women need to relax their minds, keep their moods relaxed, eat more nutritious food and replenish sufficient nutrition. Pay more attention to rest in daily life to avoid discomfort caused by overexertion, and perform timely maternity checkups to pay attention to the growth and development of the fetus. If you experience vague pain in the lower right abdomen, you should seek medical attention and be alert to the occurrence of diseases such as appendicitis.
