Eosinophilic gastroenteritis generally manifests itself clinically as nausea, vomiting, abdominal pain, jaundice, and ascites. Eosinophilic gastroenteritis is a disease caused by eosinophilic infiltration of the gastrointestinal tract, often involving the gastric sinus, colon, and even the liver and other organs. The pathology is usually characterized by edema of the gastrointestinal tract without glandular destruction. Eosinophilic gastroenteritis has different clinical manifestations in different lesion sites, which are generally nonspecific and related to the degree of infiltration. If the stomach or colon is involved, there may be intestinal obstruction, ascites, abdominal pain, nausea and vomiting; if the liver or gallbladder is involved, jaundice may occur. In addition to these, eosinophilic gastroenteritis may be accompanied by symptoms such as asthma, delayed puberty, amenorrhea, and weight loss. It is worth noting that patients should be alert to the complications of eosinophilic gastroenteritis, such as esophagitis, gastric ulcer, appendicitis, etc., when suffering from eosinophilic gastroenteritis. If the patient has gastrointestinal discomfort, it is recommended to go to the hospital as soon as possible.
