Generally there is no need for fasting to measure progesterone, but it needs to be measured at a specific time. Progesterone is mainly secreted by the corpus luteum of the ovary and is a progesterone hormone in a woman’s body, which is closely related to the formation of menstruation and the growth and development of the fetus. Since hormones such as progesterone do not have a strong relationship with diet, there is no need to test on an empty stomach. However, progesterone and other hormones are secreted in pulses, and the value of progesterone measured at different times of the day may be different. When you are pregnant, if the progesterone is low, it is easy to cause miscarriage. If the progesterone is low, you can take progesterone intramuscular injections or oral progesterone tablets under the guidance of your doctor, etc. And you should have regular checkups to monitor it at all times. When you are pregnant, you should also eat more foods that are high in progesterone, such as milk and soybeans.
