When a threatened miscarriage occurs, the pregnant woman often experiences abdominal pain and vaginal bleeding. The specific timing of the abdominal pain can vary, as each individual's situation is different. Some may experience longer periods of pain, while others may have shorter ones. During a threatened miscarriage, it is essential to go to the hospital promptly for treatment to preserve the pregnancy. If the bleeding stops after active treatment, then it is possible to continue the pregnancy. However, if the symptoms do not relieve and the pain intensifies after treatment, then it is no longer feasible to continue preserving the pregnancy, and an abortion surgery will be necessary.

How long does it take to prevent a threatened miscarriage?

During threatened miscarriage, proactive treatment to preserve the pregnancy is required. However, the duration of such treatment varies from person to person and should be based on the specific circumstances of the patient. If the patient has a history of recurrent miscarriages, in the event of a threatened miscarriage, the pregnancy should be preserved for a longer period, at least until three months into the pregnancy when the fetal development has stabilized. However, if the patient experiences light vaginal bleeding without abdominal pain, and the condition is relatively mild, approximately a week of medication may be sufficient for improvement. It is recommended that one to two weeks after the bleeding stops, a visit to the hospital should be made to perform an abdominal ultrasound to check the embryo's growth.

What foods are good for threatened miscarriage?

When experiencing signs of threatened miscarriage, pregnant women should choose foods rich in vitamins and pay attention to a light diet, eating food that is easy to digest and absorb. They should avoid spicy and stimulating foods, as well as raw and cold seafood or other barbecue and hot pot foods, to prevent diarrhea and aggravate the miscarriage. When choosing foods, one can opt for soy products, fresh vegetables, fruits, lean meats, eggs, and walnuts. Additionally, it is advisable to select foods that are rich in vitamin E, which supports pregnancy, such as some soy products. It is also beneficial to choose foods containing roughage but avoid cold foods and thermogenic foods like longan, as longan is very heaty and should be avoided as it might induce miscarriage.

Can threatened miscarriage be treated with medical abortion?

Threatened miscarriage only indicates signs of a potential miscarriage and does not necessarily result in a spontaneous miscarriage. During a threatened miscarriage, medication can be used to preserve the embryo. If one does not wish to continue the pregnancy upon signs of a threatened miscarriage, intervention can be managed like a normal miscarriage. In early pregnancy, if one chooses to have an abortion, there are two methods available: medical abortion and surgical abortion, which are not significantly different from each other. For the majority of typical women, medical abortion is an option during a threatened miscarriage, though it is notably painful and can be prolonged. Patients must be clearly informed about the specific procedures and drawbacks. Surgical abortion, on the other hand, tends to be simpler and less painful.

What are the symptoms of threatened miscarriage?

Threatened miscarriage refers to a small amount of vaginal bleeding occurring before 28 weeks of pregnancy. Usually, the amount of bleeding does not exceed that of a normal menstrual period, and the blood may be dark red or appear as bloody vaginal discharge. The color of the bleeding is not significant. No pregnancy tissue is expelled initially, and this may be followed by episodic lower abdominal pain or back pain, although these symptoms may not occur. During a gynecological examination, the cervix is closed, the membranes are intact, and the size of the uterus corresponds to the gestational age. After rest and treatment, the symptoms may disappear, and the pregnancy can continue. If the amount of vaginal bleeding increases or lower abdominal pain intensifies, accompanied by the expulsion of pregnancy tissue, it progresses to inevitable miscarriage. Inevitable miscarriage refers to a miscarriage that cannot be avoided. Based on the symptoms of a threatened miscarriage, the amount of vaginal bleeding increases, and episodic lower abdominal pain intensifies, possibly accompanied by vaginal fluid discharge. During a gynecological examination for inevitable miscarriage, the cervix is dilated, and embryonic tissue or the amniotic sac can be seen obstructing the cervical opening.

What to do about a threatened miscarriage?

Threatened miscarriage refers to the occurrence of a small amount of vaginal bleeding before 28 weeks of pregnancy, often dark red, with no pregnancy tissue expelled, and may include pain in the lower abdomen and back. During a gynecological examination, the cervix is closed and the membrane is unruptured, and the pregnancy can continue if the symptoms disappear after rest and treatment. In handling a threatened miscarriage, it is first necessary to analyze the causes of the miscarriage. Common causes include embryonic factors, mainly chromosomal abnormalities. If the miscarriage is caused by chromosomal abnormalities, it is mostly unavoidable. Maternal factors, such as systemic diseases in pregnant women, include increased blood pressure, severe anemia, high fever, etc. Pregnancy can mostly continue with treatment of the cause. Abnormalities in the reproductive organs, such as uterine malformations, submucous and intramural fibroids, adenomyosis, etc., can lead to miscarriage. With appropriate treatment to preserve the pregnancy, there is hope to continue the pregnancy. If due to endocrine abnormalities, such as luteal phase deficiency or hypothyroidism, supplementing with progesterone and thyroid hormones can mostly allow the pregnancy to continue. Identifying the cause of a miscarriage is extremely important, as different causes can lead to different pregnancy outcomes.
