It is not uncommon for adults to have umbiliculitis. In mild cases, the main problem is discomfort in the umbilicus, and there is always something smelly in the umbilicus; in severe cases, there can be redness, swelling, heat, pain, pus, and even purulent infection around the umbilicus, and abscess formation; if not treated properly, the condition can recur, affecting life and work and causing unbearable suffering. According to my experience, almost all adult umbilical infections are related to poor hygiene habits in the umbilicus, due to the misconception that the umbilicus cannot be cleaned and that cleaning the umbilicus will cause the abdomen to “leak”, resulting in foreign objects such as hair, dirt and even “umbilical stones” in the umbilicus. This results in foreign bodies such as hair, dirt and even “umbilical stones” in the umbilicus. Repeated stimulation of foreign bodies leads to infection, especially in the hot summer, when bacteria are prone to multiply and are more likely to develop. If the umbilicus is deep, you can use turpentine or alcohol swabs to wipe the dirt inside, then wash it with water and dry it with cotton swabs. Once infection occurs, it is also necessary to apply local antibiotics such as chloramphenicol drops, Bactrim, etc., orally or intravenously in severe cases, after carefully removing foreign bodies such as hair in the umbilicus. In severe cases, oral or intravenous antibiotics may be administered. In cases of periumbilical abscess formation, incision and drainage may also be required. Some young women worry that umbilical infection will affect their fertility, which is superfluous, but getting pregnant after curing umbilical infection is undoubtedly positive for the pregnant woman and the fetus, and can save a lot of unnecessary worries.
