Changes in gastrointestinal motility and gut hormone secretion after Roux‐en‐Y gastric bypass and sleeve gastrectomy for individuals with severe obesity

Clinical Obesity, Volume 15, Issue 2, April 2025.
Summary Background Bariatric surgery is very effective in long‐term weight management. The present study was undertaken to investigate the short‐term effects of sleeve gastrectomy (SG) and of Roux‐en‐Y gastric bypass (RYGB) on (a) gastrointestinal (GI) motility, that is gastric emptying and oro‐cecal transit time and (b) secretion of regulatory gut ...

Ghrelin and LEAP2: Their Interaction Effect on Appetite Regulation and the Alterations in Their Levels Following Bariatric Surgery

Medicina
Background and Objectives: Ghrelin plays key roles in appetite regulation, involving both homeostatic and hedonic pathways. In obesity, its metabolism is affected by alterations in neural and hormonal responses.

Regulation of the Human Ghrelin Promoter Activity by Transcription Factors, NF-κB and Nkx2.2

International Journal of Endocrinology, 2015
To examine the gene expression of ghrelin, a growth hormone releasing and appetite stimulating hormone from stomach, we constructed human ghrelin promoter-reporter vectors and analyzed the promoter activity.

Novel regulator of acylated ghrelin, CF801, reduces weight gain, rebound feeding after a fast, and adiposity in mice

Frontiers in Endocrinology, 2015
Ghrelin is a 28 amino-acid hormonal peptide that is intimately related to the regulation of food intake and body weight. Once secreted, ghrelin binds to the growth hormone secretagogue receptor-1a (GHSR-1a), the only known receptor for ghrelin and is ...

Glucocorticoids and HPA axis regulation in the stress–obesity connection: A comprehensive overview of biological, physiological and behavioural dimensions

Clinical Obesity, Volume 15, Issue 2, April 2025.
Summary Chronic stress, characterized by increased long‐term exposure to the glucocorticoid hormone cortisol, is increasingly linked to obesity development. Still, various knowledge gaps persist, including on underlying pathophysiological mechanisms. The aim of the current review is to provide the latest insights on the connection between stress and ...

Intragastric Balloon Treatment Enhances Weight Maintenance Adjunct to Low‐Energy Diet and Group‐Based Cognitive Behavioural Therapy: A Randomized Controlled Trial

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Low‐energy diet (LED) plus cognitive‐behavioural therapy (CBT) produces substantial short‐term weight loss in obesity, but long‐term maintenance remains difficult. We evaluated whether adding intragastric balloon (IGB) treatment to group‐based CBT improves weight maintenance after initial weight loss using LED.

Liver-expressed antimicrobial peptide 2 elevation contributes to age-associated cognitive decline

JCI Insight, 2023
Elderly individuals frequently report cognitive decline, while various studies indicate hippocampal functional declines with advancing age. Hippocampal function is influenced by ghrelin through hippocampus-expressed growth hormone secretagogue receptor ...

Does Sleep Curtailment Stimulate Appetite, Motivation to Eat and Dietary Intake in Humans? A Narrative Synthesis of Evidence and Considerations for Future Studies

Journal of Sleep Research, EarlyView.
ABSTRACT Insufficient sleep has been increasingly recognised as a risk factor for obesity, yet the underlying mechanisms remain incompletely understood. Research suggests that sleep restriction promotes excessive dietary intake, and it is commonly assumed that this relationship can be explained by appetite dysregulation.

Expression of Ghrelin and Its Receptor mRNA in Bovine Oocyte and Cumulus Cells [PDF]

International Journal of Fertility and Sterility, 2019
Energy balance is regulated by ghrelin which is a neuroendocrine modulator. Ghrelin is expressed in repro- ductive organs. However, the role of ghrelin during in vitro maturation (IVM) and bovine preimplantational development is limited. The purpose of
