Intestinal lymphangiectasia is a rare condition where lymphatic vessels connecting to the small intestine become enlarged, hindering fluid transport and nutrient absorption, leading to malabsorption and hypoproteinemia. Treatment depends on the cause and diet adjustment to facilitate nutrient absorption. A low-fat, high-protein diet and nutritional supplements are used long-term. Parents of children with the condition should educate healthcare professionals about the need for a restrictive diet and supplements.
Intestinal lymphangiectasia is a rare condition in which the lymphatic vessels that connect to the small intestine become enlarged, which hinders their ability to transport fluids. This inhibits the body’s ability to process fat and absorb protein and can lead to serious medical complications. There are several causes for the occurrence of intestinal lymphangiectasia, and treatment options usually depend on resolving the cause and adjusting the patient’s diet to facilitate the patient’s absorption of nutrients.
In healthy patients, lymph vessels that connect with the small intestine carry fats that have been digested from the small intestine, along with proteins. In a patient with intestinal lymphangiectasia, these fluids stay in the intestines instead of being transported in the lymph vessels because the vessels are swollen. The patient experiences diarrhea and may develop nausea, vomiting, and abdominal pain. Some patients also experience lymphedema.
This is a condition of malabsorption, characterized by difficulty absorbing necessary dietary nutrients. Intestinal lymphangiectasia is specifically a form of protein-losing enteropathy, which means that the patient experiences protein loss through the intestines and may develop a condition called hypoproteinemia, characterized by low protein content in the blood. Intestinal lymphangiectasia is diagnosed with an interview with the patient and a biopsy that can be used to identify enlarged lymph vessels.
In some patients, enlarged lymph vessels are congenital. In others, they may be caused by conditions such as constrictive pericarditis or pancreatitis. In these cases, the patient can be treated and over time can recover normal bowel function. While the patient is recovering, a special diet will be used to keep them healthy. This diet is used long-term for patients with congenital intestinal lymphangiectasia.
The diet for patients with this condition is low in fat and high in protein to facilitate nutrient absorption. The patient also takes nutritional supplements to confirm that she is getting the necessary dietary nutrients, including vitamins and minerals. While it can take time to adjust to the diet, patients with chronic intestinal lymphangiectasia can live very full lives. When this condition is diagnosed in young children, parents should be sure to educate healthcare professionals about the need for a restrictive diet and the need to take supplements at the right time, to clarify that the child’s diet addresses a health issue and that the high no fatty snacks or snacks should be provided.
