What causes low progesterone during pregnancy, and what should be done?

Generally, low progesterone levels during pregnancy may be related to malnutrition, medication effects, luteal insufficiency, endocrine disorders, polycystic ovary syndrome (PCOS), and other factors. It is recommended that pregnant women adjust their diet, switch medications, or take medications such as dydrogesterone tablets, Qizhi Xiangfu pills, or dexamethasone tablets under a doctor's guidance. Detailed explanations are as follows:

1. Malnutrition: Severe morning sickness symptoms in pregnant women can prevent normal eating, possibly leading to malnutrition and indirectly causing decreased progesterone levels. This may be accompanied by slow weight gain during pregnancy and intrauterine fetal growth restriction. It is recommended to adjust the diet to ensure sufficient intake of protein, fats, and carbohydrates.

2. Medication effects: Certain medications, such as amoxicillin capsules or cefixime capsules, may interfere with progesterone synthesis or metabolism, leading to reduced progesterone levels. Symptoms may include fatigue and hair loss as adverse drug reactions. It is recommended to switch to alternative medications with less impact on progesterone levels under a doctor's guidance.

3. Luteal insufficiency: Luteal insufficiency may result in inadequate progesterone secretion and may be accompanied by frequent menstruation, shortened menstrual cycles, and premenstrual bleeding. It is recommended to take medications such as progesterone capsules, dydrogesterone tablets, or medroxyprogesterone acetate tablets under a doctor's guidance.

4. Endocrine disorders: Prolonged mental stress, anxiety, and other emotional factors in pregnant women may interfere with hormone secretion, accompanied by mood swings and weight changes. Pregnant women should follow medical advice to use medications such as modified Xiaoyao pills, Qizhi Xiangfu pills, or Wuji Baifeng pills for treatment.

5. Polycystic ovary syndrome (PCOS): PCOS is a common endocrine disorder affecting women's reproductive health. It can prevent follicles in the ovaries from maturing and releasing eggs, affecting corpus luteum formation and progesterone secretion. Symptoms may also include weight gain, hirsutism, acne, and menstrual irregularities. Pregnant women are advised to use medications such as dexamethasone tablets, cyproterone acetate tablets, or combined valerate estradiol tablets under a doctor's guidance to alleviate symptoms.

In daily life, pregnant women should focus on a balanced diet, consume adequate vitamins and protein, ensure sufficient rest, and avoid excessive fatigue.
