Source: ClinicalTrials.gov · Last updated 3 Nov 2026
Brief summary (registry, in English)
Background: Diabetes and obesity are chronic diseases. They can affect blood flow and how the body processes nutrients, and complications over time can lead to early death. Diabetes can affect children as well as adults, but the disease seems to be more severe and to progress faster when it appears in younger people. Researchers want to understand more about how diabetes and obesity develop and change over time. Objective: To collect data and samples regularly from people with obesity and diabetes. Eligibility: People aged 8 to 65 years. They must be overweight or obese; or have high blood sugar; or have problems with how their body uses food for energy. Design: Participants will have additional procedures during routine care visits at the NIH clinic. Data collected for the study will include the following: Information from the participant s medical chart will be kept for research. Questionnaires will ask about participant s eating habits, feelings, sleep, and substance use. They will take 30 to 60 minutes. Care providers will address any issues revealed in these surveys. Blood, saliva, urine, and stool samples will be collected. Samples may be used for genetic tests. Data and samples will be kept for future research. Participants may remain in the study up to 30 years.
