Active clinical trials for "Glucose Metabolism Disorders"

The goal of this observational study is to compare serum glucose and lipid metabolism levels between health volunteers and vitiligo patients. The main question it aims to answer is whether vitiligo is related to glucose and lipid metabolism disorders. Participants will complete a vitiligo questionnaire and test serum levels of indicators related to glucose and lipid metabolism. Researchers will compare vitiligo patients with healthy volunteers to see if there is a correlation between vitiligo and disorders of glucose and lipid metabolism.

The purpose of this study is to determine upon administering GABA orally to a person how it is absorbed, distributed, as well as the drug's pharmacological effects on the body such as glucose levels, serum C-peptide and/or insulin levels (referred to as pharmacokinetics/pharmacodynamics). We will conduct experiments in normal subjects to address these questions.

GLADS is a cross-sectional, observational study assessing free-living diet, physical activity, sleep, and glucose profile over a 2-week period in healthy adult men and women.

As a phase 0 clinical trial, we will learn how kombucha influences glucose metabolism in humans.

Pregnancy-associated diabetes, known as gestational diabetes mellitus (GDM), is associated with an increased lifetime risk of developing diabetes mellitus (DM) or pre-diabetes. Up to 30% of women with GDM will continue have abnormal blood glucose tests 6 or more weeks after delivery. Early diagnosis and treatment of continued impaired glucose metabolism or DM is essential because serious health problems can result. Current guidelines recommend a 75-gram, 2-hour glucose tolerance test (GTT) 6 or more weeks after delivery for women diagnosed with GDM in order to identify those with continued DM or impaired glucose metabolism. However, approximately half of these women do not get glucose testing after delivery. The ability to test women while they are still hospitalized after having a baby could greatly increase diagnosis, care and treatment of women with abnormal glucose metabolism. Our objective is to determine if a 75-gram, 2-hour GTT administered to women with GDM two to four days after delivery can identify those who will have an abnormal GTT at 6-12 weeks after delivery.

The effect of cholecystectomy on postprandial plasma GLP-1 responses (primary endpoint) and glucose metabolism will be evaluated in 30 patients planned to undergo elective laparoscopic cholecystectomy.

In the present study glucose metabolism and ectopic lipids in the liver, heart and muscle were investigated in women with the polycystic ovary syndrome (PCOS) and in healthy control subjects.

The investigators want to evaluate the difference in glucose metabolism and intestinal hormonal response after a liquid meal versus a solid meal in patients after bariatric surgery.

Delineation of the anatomical location, cellular origin and molecular basis of gut-derived glucagon secretion

Experiments have shown that some artificial sweeteners like those in diet soda can cause changes in how the body responds to and uses sugar. These changes increase the chance of obesity, type 2 diabetes, and other metabolic diseases. In this study, the investigators plan to see if the most common artificial sweetener, aspartame (brand name Equal, NutraSweet), causes these changes. The investigators believe that if metabolic changes are observed in a person who consumes aspartame, then removing all aspartame from the diet might lead to a reversal of the changes and a normalization of test results.This would impact sweetener additives in our foods and thus decrease the incidence of obesity, diabetes, and the metabolic syndrome.
