The hormone mentioned here is what we call glucocorticoid, which is a type of hormone secreted by the adrenal cortex and has a very important role in regulating fat, blood sugar and protein metabolism. Patients who take hormones for a long time will become fat, and this kind of fat is different from the normal fat, because the normal fat is uniformly obese, such as the limbs are also fat, and the trunk is also fat. The hormone-induced obesity is not a normal obesity, but mainly manifests as fat and redness on the face, increased fat on the trunk, including the buttocks, and some streaks on the thighs or abdomen, but the limbs are thin, so we call this kind of obesity full-moon face or centripetal obesity, which is completely different from the normal obesity, mainly due to the side effects of hormones. If the hormone dosage is gradually reduced until it is discontinued, the obesity caused by hormones may gradually disappear, but this may take a longer time.
