Low progesterone can affect the normal menstrual cycle of non-pregnant women. If progesterone is low after pregnancy, it suggests the possible existence of hypoplasticity, ectopic pregnancy, preterm miscarriage and other diseases. Progesterone supplementation mainly includes natural progesterone and synthetic progesterone.1. Natural progesterone: refers to the natural progesterone isolated from the corpus luteum, including progesterone capsules, progesterone injection, micronized progesterone, etc. Progesterone injection can be injected intramuscularly, as it will not be absorbed through the gastrointestinal tract and enter the body circulation directly, and is suitable for women who have obvious nausea and dizziness after taking progesterone capsules orally. 2. Synthetic progesterone: It is mainly synthesized through artificial chemical synthesis, and its function is similar to that of progesterone, such as medroxyprogesterone acetate tablets, progesterone vaginal delayed-release gel and dextran tablets, which can also supplement the progesterone in the body. Progesterone vaginal extended-release gel is usually administered vaginally and is suitable for women who need long-term progesterone supplementation. If the progesterone level is only slightly low, you can eat more foods containing progesterone in your regular diet, such as purple cabbage, spinach, soybeans, lemon, walnuts, kudzu, etc. Or you can eat more foods containing vitamin E and pectin, such as peaches, pears, strawberries, etc. If the progesterone value is low is more serious, it is recommended to go to the hospital to actively cooperate with the doctor for drug treatment, need to strictly follow the doctor’s instructions for medication, avoid progesterone oversupply.
