Summary

Hypoglycemia is the term used to refer to lower than normal levels of blood sugar. This study will continue to research the causes of hypoglycemia. Patients involved in the study will be admitted to the Clinical Center of the National Institutes of Health and undergo tests for evaluating blood sugar. Patients will be required to refrain from eating for a set period of time and will undergo blood tests for insulin levels and several other specific diagnostic tests related to insulin secretion. The patients will be under supervision and will be provided with appropriate medical and surgical attention as needed.

Detailed description

Study Description: The purpose of this study is to gain knowledge and experience in the diagnosis and therapy of patients with fasting hypoglycemia due to diverse etiologies, such as insulinomas. Study subjects will be evaluated and treated for their particular condition according to standard care. Objectives: 1. To understand the pathophysiology and various causes of hypoglycemia (e.g., insulinomas, MEN1, MEN2). 2. To identify new circulating biomarkers of insulinomas. 3. To create a repository of clinical data and samples for future research of insulinomas. Endpoints: None
