Chronic enteritis can be severe with recurrent abdominal pain, diarrhea, mucus stools, nausea, vomiting, and other symptoms, and complications such as intestinal bleeding and intestinal stenosis may also occur. Chronic enteritis refers to chronic inflammation of the intestinal mucosa caused by infection, immunity, genetics and other reasons. Patients often manifest long-term chronic or recurrent abdominal pain, varying degrees of diarrhea, and in severe cases, mucus or watery stools. When the patient’s rectum is seriously involved, there may also be a sense of urgency (discomfort in the lower abdomen, wanting to relieve the bowel movement, and a sense of incomplete evacuation after the bowel movement). Due to the long duration and recurrent episodes of chronic enteritis, patients may experience generalized symptoms such as depression, weakness of limbs and pallor. Long-term chronic enteritis may also cause intestinal bleeding, intestinal stenosis, and cancer. After active and effective treatment of chronic enteritis, the general symptoms can be relieved. However, chronic enteritis is prone to prolonged delay or recurrence, which affects the patient’s psychological state, and family members should help him/her to adjust his/her state of mind and eliminate bad emotions. Patients should follow the doctor’s instructions to take medication strictly, have regular work and rest, and exercise appropriately in order to enhance physical fitness and promote the recovery of the disease. Once abdominal pain, diarrhea, nausea and other symptoms, should pay attention to timely consultation, identify the cause of the disease, and cooperate with the doctor’s treatment.
