I. About eating or not eating protein powder In the clinic, we find that protein powder is particularly popular, but do you really need to eat protein powder? During IVF treatment, we recommend protein powder for women with ovarian hyperstimulation syndrome, as they need to treat this complication by increasing serum protein. For women who do not have complications, they do not need to consume protein powder, as healthy people do not need to supplement with protein powder. For women with metabolic problems or obesity, taking protein powder is rather detrimental and the metabolic problems may get worse. On the other hand, long-term consumption of protein powder will increase the burden on the liver and kidneys. Second, about hysteroscopy and endometrial pathology Some women need to perform hysteroscopy, in addition to the microscopic look at the uterine cavity morphology and endometrial condition, we also want to know the endometrial pathology results, whether there is endometritis. However, some hospitals are not able to check the inflammatory indexes CD138 and CD38, so it is recommended that women who need hysteroscopy should ask the doctor if they can check these two inflammatory indexes before they go for hysteroscopy, and if not, let’s change to another hospital that can do hysteroscopy and endometrial pathology.
