It is important for adults to have roundworms in their stomachs and to come to the hospital for examination and treatment. The reason is that the presence of roundworms in the stomach can cause pain in the abdomen of the patient. If the roundworm is relatively small, the pain is relatively light and transient, but if the roundworm is relatively large, it can suck a lot of nutrients from the patient by multiplying in the body, resulting in malnutrition and weight loss. At the same time, roundworms gather in the intestinal canal and form a mass, which can lead to acute intestinal obstruction and intestinal strangulation, and surgery is needed when necessary. If the roundworm burrows into the patient’s bile duct and forms an obstruction, biliary colic and jaundice will occur, requiring timely surgical treatment. Generally speaking, if the roundworms are relatively small, deworming treatment is available, and you can take 0.4 grams of intestinal wormer orally, and you can take it in a meal, and you should pay attention to the patient’s abdominal pain during the deworming treatment.
