The main danger of celiac disease is that it may lead to renal colic, abnormal urination, and nutritional disorders. Celiac disease means that the celiac fluid absorbed by the intestinal tract flows backward into the lymphatic vessels of the urinary system and is not drained into the bloodstream according to the normal lymphatic channels, thus increasing the pressure in the lymphatic vessels, causing the lymphatic vessels to become varicose and rupture, resulting in the overflow of celiac fluid into the urine, making the urine appear milky and cheese-like. Patients with celiac disease are usually accompanied by lumbar distension and pain, and if celiac disease and blood clots are formed, renal colic may occur due to the stimulation of these two substances, and if the celiac clot blocks the urethra, it may also cause urinary abnormalities. If celiac disease is recurrent, it will cause loss of nutrients in the body, and symptoms such as fatigue, anemia, malnutrition and ascites will occur. It is recommended that patients with symptoms of celiac disease seek medical attention for early treatment.
