Gastrointestinal dysfunction is generally related to dietary stimuli, pathological factors, mental factors, etc. It is impossible to generalize how long it takes to get well. Gastrointestinal dysfunction is often caused by pathological factors, such as indigestion, gastritis, ulcer disease, acute gastroenteritis, or mental factors, such as emotional tension, anxiety, worry, etc., which affect the gastrointestinal function and thus cause gastrointestinal dysfunction. If the patient’s condition is mild and he/she can actively improve the bad eating habits, such as eating regularly, not eating spicy and irritating food, and cooperate with the doctor, he/she may be relieved after 1-2 weeks. However, some patients with more severe and longer duration of the disease have a longer treatment process and may need 1-3 years or more of conditioning to gradually get better. Symptoms of gastrointestinal dysfunction may appear repeatedly or indirectly, causing inconvenience to life and may even affect the quality of life. Patients are advised to visit the gastroenterology department in a timely manner and undergo regular and standardized treatment under the guidance of a doctor.
