The Mannion IUD is generally less likely to cause weight gain and to a lesser extent. The IUD is an intrauterine device (IUD) with a drug-releasing effect. The main indications are contraception, idiopathic menorrhagia (i.e., menorrhagia not caused by organic pathology), and uterine adenomyosis. The main component of the drug is levonorgestrel, which is a progestin component. Progesterone, like estrogen, is a sex hormone and can produce edema as a side effect to a certain extent, but because the dose of the drug in the Mannuel Ring is small and the effect is localized, it is less likely to cause obesity and to a lesser extent. Therefore, if a patient develops weight gain after the placement of the Mannuelle ring, other causes of weight gain may need to be prioritized, such as a prolonged high-fat diet, age, and other factors. If there is bleeding or lower abdominal pain during the use of the Mannix Ring, prompt hospitalization is required.
