Threatened miscarriage refers to signs of miscarriage during pregnancy, and some women with threatened miscarriage may experience nausea. This situation includes several reasons: First, threatened miscarriage is not the same as a natural miscarriage; women are still pregnant, hence early pregnancy reactions such as nausea are normal. If the nausea is mild, rest and observation are advisable. However, if severe, it is important to visit the hospital for an examination to rule out hyperemesis gravidarum. Second, some cases of threatened miscarriage are caused by gastrointestinal inflammation, such as acute gastritis causing uterine contractions, which then leads to threatened miscarriage. The nausea in these situations is due to acute gastritis, so the nausea is a symptom caused by the condition that leads to the threatened miscarriage, not a direct result of the threatened miscarriage itself.

What are the symptoms of a threatened miscarriage?

When threatened miscarriage occurs, pregnant women often experience vaginal bleeding and abdominal pain. However, at this time, the fetal heartbeat and embryo are generally still in good condition, and timely treatment to preserve the pregnancy can be effective. But if the patient experiences a significant amount of bleeding and severe pain, accompanied by backache and a sense of heaviness, it may indicate a threatened miscarriage. It is advised to go to a hospital for an ultrasound examination and to have blood tests to check progesterone levels to determine if treatment to preserve the pregnancy is needed. If, after such treatment, vaginal bleeding stops and abdominal pain disappears, then the pregnancy can typically continue.

Is threatened miscarriage dangerous?

There are various causes of threatened miscarriage, so the danger of a threatened miscarriage depends on the cause. If the reason for the threatened miscarriage is due to abnormal fetal chromosome development, gynecological inflammation, or endocrine dysfunction, then it is necessary to receive timely treatment. If fetal development abnormalities are detected, the pregnancy must be terminated promptly and cannot continue. However, if the threatened miscarriage is simply due to low progesterone levels, then generally, the pregnancy can be successfully maintained by timely supplementation of progesterone, and this situation is not severe.

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 should you not eat during a threatened miscarriage?

When there are signs of a threatened miscarriage, pregnant women should avoid consuming raw, cold, spicy, and irritating food such as onions, ginger, garlic, chili peppers, and overly sour food, as these may stimulate the uterus, causing it to contract, and increase the risk of miscarriage. Additionally, do not consume cold-natured foods, especially chilled beverages straight from the refrigerator or melons and fruits. Also, some foods can cause uterine contractions, such as hawthorn, seafood products, and black fungus; these should be avoided during this period. Also, try not to be overly anxious.
