Gastrointestinal diseases, if left untreated, may cause long-term chronic damage to the gastrointestinal tract, and in severe cases, may directly increase the risk of gastrointestinal cancers. 1. Chronic gastrointestinal diseases: If gastrointestinal diseases are not treated in time, it will lead to the persistence of the original inflammation or mucous membrane damage, etc., and cause the damage to aggravate or inflammation to spread under the stimulation of various factors. At the same time, it will also affect the liver, gallbladder, pancreas and other organs in the digestive system, thus causing extensive damage or dysfunction. 2. Malnutrition: The human body mainly relies on the digestion and absorption of the gastrointestinal tract to supply nutrients, and the persistence of gastrointestinal diseases will affect the digestion and absorption function of the digestive tract, resulting in malnutrition. 3. Gastrointestinal cancer: when chronic gastrointestinal inflammation persists and is not effectively treated in time, it will greatly increase the chances of malignant lesions such as gastric cancer, colorectal cancer or rectal cancer. Therefore, for people with early gastric disease or chronic gastrointestinal injury, early treatment and gastrointestinal protection are needed to effectively avoid the occurrence of malignant tumors. If gastrointestinal diseases are not treated in time, there are many other consequences. After the appearance of gastrointestinal diseases, it is necessary to go to the hospital as soon as possible for gastroenteroscopy or imaging examination, and choose the appropriate treatment for early treatment according to the specific cause of the disease, so as to avoid delaying the condition.
