This pattern typically results from improper or unsanitary eating habits and is more common in individuals with cold, weak constitutions. The movement of parasites within the abdomen, particularly in the Small Intestine, leads to pain that shifts location as the parasites move, often being most pronounced around the periumbilical area.

If these parasites disturb the Stomach, they can disrupt the organ's Qi, impairing its descending function and potentially causing vomiting of clear fluids or the parasites themselves. This pattern emphasizes the importance of dietary habits and constitutional factors in the development and manifestation of parasitic infections within the body.
