What causes fluid discharge from the navel?

Under normal circumstances, watery discharge from the navel may be caused by poor personal hygiene, omphalitis, umbilical hernia, urachal fistula, or sebaceous cysts. It is recommended to seek medical attention promptly to determine the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Poor Personal Hygiene

If personal hygiene is neglected, dirt and bacteria can accumulate in the navel, leading to discharge accompanied by symptoms such as odor and itching. It is recommended to regularly clean the navel with warm water and a mild cleanser, then dry it thoroughly with a clean towel.

2. Omphalitis

This may be caused by skin injury or bacterial infection, resulting in local exudation of tissue fluid and watery discharge, often accompanied by redness, swelling, and pain. Treatment under medical guidance may include topical medications such as erythromycin ointment, mupirocin ointment, or hydrogen peroxide solution.

3. Umbilical Hernia

This is usually caused by increased intra-abdominal pressure, which prevents the muscles around the navel from effectively closing the abdominal wall, potentially leading to navel discharge. Symptoms may include a localized lump and pain. Treatment may involve using a hernia belt or small wooden splints as directed by a physician.

4. Urachal Fistula

This condition is typically congenital, caused by developmental abnormalities of the urachus, leading to discharge from the navel or leakage of urine through the umbilical opening. Surgical intervention, such as open surgery or laparoscopic surgery, is required and should be performed under medical supervision.

5. Sebaceous Cyst

This is generally caused by blockage of the hair follicle or sebaceous gland duct. If the cyst develops in the navel area, rupture can lead to discharge and pain. Laser surgery or other procedures as recommended by a doctor are advised.

In daily life, it is important to maintain healthy habits, such as going to bed early and waking up early, aiming to sleep before 11 p.m. each night and avoiding staying up late, ensuring sufficient rest. Diet should be light and easily digestible. Foods rich in nutrition—such as lean meat, fish, eggs, milk, and carrots—are recommended to support immune function.
