The reason why the navel patch works is because the medicine in the navel patch enters the human body through the navel, which promotes blood circulation and stimulates the stomach. Therefore, the metabolism will be faster after using the navel patch, and it may also cause gastrointestinal dysfunction. So there will be frequent farting and frequent ringing in the stomach. General doctors will call this situation, because bowel sounds caused by intestinal dysfunction may be normal in a short time, but if you always fart and your stomach sounds, it may be spleen and stomach disorders at this time, so it is recommended to stop using it.
In fact, belly button stickers can cause certain side effects. If you feel unwell for a long time, it is recommended to stop using belly button patch as soon as possible. In addition, if the belly button sticker is to lose weight, you don't mind using it, because it is likely to cause a rebound. Especially for people with bad stomach or high blood pressure and hypoglycemia, don't use navel stickers.
