Patients with IBS do not experience pain when pressing on the abdomen, which means that there is little to no pressure pain or other abdominal signs. In both acute and chronic gastroenteritis, the main clinical symptoms are dominated by the patient’s subjective sensations. Patients may present with abdominal pain, nausea, vomiting, diarrhea, loss of appetite, etc., but there is little to no pressure or muscle tension on abdominal examination. Acute gastroenteritis is recommended to be treated with acid suppressants combined with probiotics, and if bacterial or viral infection is clearly present, additional antibiotics or antiviral drugs can be given under the guidance of a specialist. For chronic gastroenteritis, if the clinical symptoms are not obvious, there is no need to use medication for the time being, you can consult a specialist for details.
