What are the causes of threatened miscarriage?

Threatened abortion is often caused by the combined effect of multiple internal and external factors. You should seek medical attention promptly to identify the cause and avoid serious consequences.

From a medical point of view, threatened abortion mainly refers to vaginal bleeding before 28 weeks of pregnancy, which may be accompanied by symptoms such as lower abdominal pain, which is a "danger signal" sent by the body. Common causes include abnormalities in the embryo itself, maternal health problems or adverse external stimuli. For example, chromosomal abnormalities in the embryo are the main cause, accounting for more than 50%. Maternal endocrine disorders, uterine malformations, severe infections, etc. can also increase risk factors. External causes such as overwork, drastic mood swings or external impacts may also be triggers.

If similar symptoms occur in the body, you should immediately reduce your activities and pay attention to bed rest, and avoid lifting heavy objects or doing strenuous exercise. Mental stability is also important. You may try to take deep breaths or communicate with your family to relieve tension. You can choose light and easily digestible foods and avoid spicy food. Expectant mothers need to avoid self-medication and must go to the hospital for examination in time. The doctor will make a detailed evaluation and give treatment advice to protect the health of themselves and the fetus.
