👉 Enteritis is a condition in which the immune system mistakenly attacks and inflames the lining of the digestive tract, causing inflammation and pain. This can occur when there is an infection or inflammation in the stomach, small intestine, colon, or rectum. The exact cause is not always known, but factors such as stress, poor diet, and certain medications have been linked to enteritis. It's important to seek medical advice if you suspect you may be experiencing enteritis.
