What causes a missed miscarriage during pregnancy?

In general, pregnancy loss refers to embryonic or fetal demise, which may be caused by excessive stress, unhealthy lifestyle habits, malnutrition, endocrine disorders, uterine fibroids, and other factors. It is recommended to seek timely medical attention, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Excessive Stress

Long-term mental tension or significant emotional fluctuations can affect ovarian function and the uterine environment through the endocrine system, increasing the risk of fetal demise. Pregnant women should actively adjust their mindset and maintain a positive mood through relaxing activities such as yoga, walking, or listening to music.

2. Unhealthy Lifestyle Habits

Prolonged smoking, alcohol consumption during pregnancy, or frequent exposure to harmful chemicals may damage embryonic development and lead to fetal demise. Pregnant women should completely avoid smoking and drinking, steer clear of hazardous environments, and maintain a healthy lifestyle.

3. Malnutrition

A monotonous diet during pregnancy or excessive intake of high-fat and high-sugar foods may result in nutritional deficiencies or obesity, negatively affecting normal fetal development and potentially causing fetal demise. A balanced diet rich in essential vitamins and minerals should be maintained, with appropriate weight gain throughout pregnancy.

4. Endocrine Disorders

External factors such as environmental pollution and climate change may disrupt the endocrine system, leading to hormonal imbalances. Abnormal hormone secretion can result in insufficient or excessive levels of key hormones, thereby impairing embryo implantation, development, and stability, ultimately causing fetal demise. This condition is often accompanied by symptoms such as fatigue and sensitivity to cold. Medications such as estradiol valerate tablets, diethylstilbestrol tablets, or Xiaoyao Pills may be used under medical supervision.

5. Uterine Fibroids

Uterine fibroids are commonly associated with genetic factors, improper diet, and elevated hormone levels. Submucosal fibroids may alter the shape of the endometrium, interfering with successful embryo implantation and leading to fetal demise. This condition is often accompanied by symptoms such as constipation and pelvic pain. Treatment options may include Gui Zhi Fu Ling Capsules, Gong Liu Xiao Capsules, or mifepristone capsules, used under a doctor’s guidance.

Maintaining healthy lifestyle habits, ensuring a balanced and nutritious diet, avoiding exposure to harmful substances, and staying emotionally well-balanced are important for supporting maternal health during pregnancy.
