The sperm and egg meet to form a fertilized egg, which is transported through the fallopian tube to the uterus where it develops into an embryo, but the “stray” embryo can develop into an ectopic pregnancy, commonly known as an ectopic pregnancy. Ectopic pregnancy not only destroys a woman’s dream of motherhood, but also threatens her life. What are the symptoms of ectopic pregnancy in women? Ectopic pregnancy most commonly occurs at the fallopian tubes. Malformed or abnormal development of the fallopian tubes, such as curved, spiral or double tubal opening, can prevent the fertilized egg from entering the uterine cavity. In addition, in women who are reconnected after tubal ligation, the fertilized egg may be prevented from entering the narrow part of the reconnection, resulting in ectopic pregnancy. The rest can be caused by pressure from adjacent organ tumors, which can displace or deform the fallopian tubes, or by ectopic endometrium in the fallopian tubes. When the fertilized egg develops in the fallopian tube, it expands with the development of the embryo and then ruptures. The rupture of the fallopian tube causes massive bleeding, which can lead to shock in serious cases and can be life-threatening if not rescued in time. What are the symptoms of ectopic pregnancy in women? Menopause: Before the tubal pregnancy miscarries or ruptures, the symptoms and signs are not obvious, except for short-term menopause and pregnancy manifestations, and sometimes there is distension and pain in one side of the lower abdomen. On examination, the fallopian tube is normal or enlarged. Abdominal pain: cramping pain in the lower abdomen, with a sensation of defecation, sometimes severe, accompanied by cold sweat. In case of rupture, the patient feels a sudden tearing pain on one side of the lower abdomen, often accompanied by nausea and vomiting. Vaginal bleeding: often a small amount of bleeding. Syncope and shock: Due to acute intra-abdominal bleeding, it can cause blood volume reduction and severe abdominal pain, often syncope in mild cases and shock in severe cases. Other symptoms: there can be nausea, vomiting and frequent urination. Symptoms of ectopic pregnancy are often atypical, and some patients experience shock due to hemorrhage, pallor and decreased blood pressure.
