Taking progesterone orally for a short period of time will not cause obesity, because progesterone can play a role in growing the endometrium and preserving the fetus. If the purpose is to promote menstruation, then only 7-10 days of oral intake is sufficient. Taking oral intake for a short period of time will not affect the health of the body, will not cause edema in the interstitial tissue, and will not cause obesity. For example, even if you take it orally for a longer period of time, more than 1 month or 2 months, if you drink a lot of water, you can promote your body’s metabolism and blood circulation, which can reduce the occurrence of fat. Moreover, some women may experience nausea, vomiting or even headache after taking progesterone orally, which can be observed according to their own situation, as not every woman will have such adverse reactions. After taking oral medication, it is important to drink as much water as possible to speed up metabolism.
