Overview
Protein losing enteropathy is the loss of plasma proteins from the gastrointestinal tract caused by an array of abnormalities

Common Causes
Most cases of protein losing enteropathy are caused as a result of:
- Primary gastrointestinal disorders
- Lymphatic obstruction
=== Primary Gastrointestinal Diseases === [1]
Mucosal Erosions/Ulcerations
Primary gastrointestinal diseases causing erosion or ulceration of the mucosa of the gut leading to fecal loss of proteins such as:
- Inflammatory bowel diseases (Crohn disease, Ulcerative colitis)
- Malignancies involving the gut mucosa
- Graft vs. host disease
- Esophageal and gastric erosions or ulcerations
- Carcinoid syndrome
- Bacterial infection with Clostridium difficile causing pseudomembranous colitis
- Parasitic infection with Giardia
Non-Erosive/Ulcerative Mucosal involvement
- Celiac disease
- Eosinophilic gastritis
- Hypertrophic gastritis
- Connective tissue disorders: Systemic lupus erythematosus
- Cutaneous burns [2]
Lymphatic Obstruction
Conditions responsible for causing lymphatic obstruction leading to the leakage of lymph into the lumen of gut such as:
- Lymphoma
- Congenital or acquired lymphatic diseases
- Lymphatic filariasis
- Sarcoidosis
- Cardiovascular diseases: Congestive heart failure, Restrictive pericarditis
- Intestinal Tuberculosis
- Fortan surgical procedure
- Cirrhosis with portal hypertension
- Retroperitoneal fibrosis
Complete Differential Diagnosis Of Underlying Causes
- Acute gastroenteritis
- AIDS
- Allergic Gastroenteritis
- Amyloidosis
- Angioedema
- Bacterial overgrowth
- Carcinoid Syndrome
- Celiac Sprue
- Clostridium Difficile
- Congestive Heart Failure
- Connective tissue disorders
- Constrictive pericarditis
- Crohn's Disease
- Duodenal erosions or ulcerations
- Esophageal erosions or ulcerations
- Graft vs. Host Disease
- Henoch-Schonlein Purpura
- Idiopathic ulcerative jejunoileitis
- Intestinal endometriosis
- Intestinal parasites
- Kaposi Sarcoma
- Lymphoenteric fistula
- Lymphoma
- Menetrier's Disease
- Microscopic colitis
- Mucosal-based neoplasm
- Neurofibromatosis
- Protein dyscrasia
- Pseudomembranous colitis
- Retroperitoneal fibrosis
- Sarcoidosis
- Stomach (erosions, ulcerations)
- Tropical sprue
- Tuberculosis
- Ulcerative Colitis
- Whipple's Disease
Diagnosis
The diagnosis of protein losing enteropathy is typically made by excluding other causes of protein loss, such as nephrotic syndrome. Endoscopy and barium imaging can be used to localize the cause of the protein loss in the bowel.
Treatment
Treatment depends upon the underlying condition.
