Primary intestinal lymphangiectasia is a digestive disorder in which the lymph vessels supplying the lining of the small intestine are enlarged. The cause of the condition is still unknown. The signs and symptoms include swelling of the legs and abdominal discomfort, loss of lymphatic fluid into the gastrointestinal tract, protein-losing enteropathy, too little albumin in the blood, reduced levels of antibodies, and immunodeficiency. Treatment involves a special long-term diet.
