The navel is essentially a scar left by umbilical cord cutting, which can usually be a small depression or a small protrusion. The abdominal muscles below the navel form a depression, and dirty things are easily hidden in the navel. If it is not cleaned in time, it may produce odor.
The navel is the closest place for internal organs to the outside world. Never dig hard. You can try to wipe it gently with a wet cotton swab first, and the action must be light. Just wipe the edges that are easy to rub.
There was a saying on the Internet that health status was judged by the shape of navel. However, there is no relevant record in actual Chinese medicine. The navel has been formed after the umbilical cord has been cut, and its shape is relatively fixed, which is not necessarily related to health.
Of course, the child's belly button is initially protruding and has nothing to do with health. This is because the child's abdominal wall is relatively thin, and the internal organs oppress the abdominal wall before it matures, so that the navel eye is oppressed and protrudes, which is completely normal.
In addition, when the human body has diseases such as cirrhosis, hepatic ascites and chronic nephritis, the navel often protrudes. This is because the navel tissue is soft and thin, and when the abdomen is highly swollen, it will protrude. At this time, we must attach great importance to the illness.
