Symptoms of high progesterone are characterized by early pregnancy reactions such as nausea, vomiting, drowsiness, and changes in appetite. Progesterone is an estrogen that is produced by the ovaries mainly when they release a mature egg and can help the uterine lining to accept a fertilized egg. If the egg is not fertilized, the level of progesterone will drop and the woman’s period will come on schedule and she will start to bleed. If the egg is successfully fertilized, the progesterone level rises and the woman may be pregnant. In the early stages of pregnancy, nausea, vomiting, drowsiness, loss of appetite and other symptoms of early pregnancy may occur due to the increase in progesterone levels and other hormonal changes in the body. Generally, these discomforts will gradually disappear after 12 weeks of pregnancy, but the progesterone level will not drop after the symptoms disappear, and the progesterone level will drop after the delivery of the baby. If the progesterone is found to be elevated during the examination, it is recommended to consult a doctor in time to identify the specific cause and then treat the symptoms under the doctor’s guidance.
