Acute medical events such as infections often provoked worsening of symptoms, suggesting that careful monitoring and early treatment of intercurrent illnesses may be beneficial. [ncbi.nlm.nih.gov]

Treatment Treatment Options: There is no effective treatment for the overall condition. Nutritionists can provide important advice on diet to maintain good nutrition. Regular monitoring by gastroenterologists is important. [disorders.eyes.arizona.edu]

Standard Therapies Treatment The treatment of MNGIE is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. [rarediseases.org]

Prognosis The prognosis is unfavorable due to the severity of the digestive involvement with infections and the need for permanent parenteral nutrition. The documents contained in this web site are presented for information purposes only. [orpha.net]
