The main symptoms of post-acute symptoms are abdominal pain, diarrhea and thin stools. This is because in medical clinics, acute inflammatory diseases of the digestive tract are a common cause of post-acute symptoms in patients. When the digestive tract tissues such as stomach and intestines are stimulated by pathogens or external factors, it will lead to tissue congestion and peristaltic hyperactivity, resulting in continuous pain in the abdomen. In addition, because the decomposition, transformation and absorption functions of gastrointestinal tissues are seriously affected, a large amount of water and nutrients in the body will enter the lower gastrointestinal tissues at an accelerated rate and be excreted from the body through the excretory system, so most patients with this disease will have diarrhea and thin stools. For patients with such symptoms, it is recommended to go to the hospital for further examination as soon as possible to confirm the specific cause of the disease, and then carry out symptomatic treatment.
