A line on a woman’s stomach is a normal physiological line, called the abdominal line, composed of body hair and light in color, and this line is used clinically as the preferred location for a cesarean section. Once painful and uncomfortable symptoms appear around the abdominal line, it may be caused by warty epidermal nevus. This disease does not cause serious effects on the organism and poses no obvious health hazards, and can be treated with ionization, laser or freezing methods when the area is small. If the area is large, you can take oral Avium capsules or have it removed surgically under the guidance of a doctor. Women should take good care of themselves and their pubic area in daily life, wash regularly, and go to the hospital for examination as soon as the symptoms of discomfort appear. At the same time, it is recommended to wear cotton underwear and underpants in daily life, and wash them regularly to expose them to the sun, which can effectively destroy the bacteria in the clothes.
