Question
Recently, some patients have noticed an unpleasant smell around their navels. What factors might cause this, and should one be concerned that it could be a symptom of a disease?
Answer
An unpleasant smell around the navel is usually due to its connection with the abdominal cavity. Before birth, the umbilical cord was connected to the mother, through which the fetus absorbed nutrients. After birth, the umbilical cord naturally closes. Normally, the navel should not have an unusual smell. However, if the navel area is frequently rubbed or comes into contact with other items, and poor hygiene habits lead to localized uncleanliness, the navel may produce an unusual smell. This is not a serious condition; maintaining good personal hygiene habits can prevent such occurrences.
