Worms in the stomach of adults refers to intestinal parasitosis, which can lead to abnormal appetite, heterophagia, abdominal pain, weight loss and other symptoms. The parasites in the intestines feed on the semi-digested food in the intestinal lumen of the organism, and the clinical manifestations of the patients are directly related to the amount of parasites. Some patients with mild disease may have no symptoms, while patients with severe disease may have symptoms such as hyperphagia or loss of appetite, xerophagia, teeth grinding, irritability, malnutrition, emaciation and diarrhea, urticaria, and so on. Prolonged lack of effective treatment may also lead to other complications such as intestinal perforation and Ascaris lumbricoides pancreatitis. For patients with the above symptoms, it is important to seek medical examination as soon as possible and take reasonable treatment under the guidance of the doctor.
