Glucagon-like Peptide 2 (GLP-2) in Undernourished Women Improving From Histology-Confirmed Environmental Enteric Dysfunction (EED)

The goal of this clinical trial is to learn whether teduglutide, a medicine that helps the intestine heal, can improve environmental enteric dysfunction in undernourished women aged 18 to 35 years living in urban slums of Dhaka. Environmental enteric dysfunction is a long-lasting condition of the small intestine. It causes inflammation and poor absorption of nutrients. Many people with this condition do not have clear symptoms, but it can make undernutrition worse. At present, there is no proven treatment for this condition. The main questions this study aims to answer are: * Does taking teduglutide for 30 days improve damage to the small intestine, as seen on intestinal biopsy? * Does teduglutide improve blood and stool markers related to gut inflammation and nutrient absorption? Participants will: * Receive nutritional support at the start of the study * Undergo an upper gastrointestinal endoscopy to confirm environmental enteric dysfunction * Receive a daily injection of teduglutide under the skin for 30 days * Undergo repeat endoscopy and laboratory tests after treatment to assess changes in gut health The results of this study will help researchers understand whether teduglutide may be a useful treatment for environmental enteric dysfunction in undernourished adult women and will guide future, larger studies.
