White urine is most likely due to the presence of some fat particles penetrating into the urine, which is what we call the possible presence of celiac disease. Celiac disease is mainly caused by some of the celiac fluid absorbed by the intestines does not pass through the normal lymphatic system also flows into the blood and reflux into the urine, the result. In the appearance of varying degrees of milky white color, if in addition to celiac disease, but also contains blood in the urine will appear more obvious celiac hematuria. This kind of celiac disease is mostly seen in parasitic diseases, especially like filariasis. However, if the patient’s health is relatively poor, there are some malignant conditions, such as due to tuberculosis, tumors, and chest and abdominal trauma and other conditions lead to the peripheral lymphatic circulation of the kidneys is blocked, resulting in lymphatic obstruction, it will also make celiac disease into the urine, in which case there will be a more obvious white urine. If this white urine is considered to be celiac disease, a celiac disease test can help to confirm the diagnosis. Currently, the celiac disease test mainly uses some fat solvents, such as ether, to extract the celiac fluid from the urine, and then it can show red color, which means that the celiac test is positive.
