概括
人类的Roux-en-Y胃绕道 (RYGB) 不会增加Roux肢体的葡萄糖吸收,这与动物模型相反. 然而,在RYGB手术后的早期观察到结肠葡萄糖吸收的显著增加.
科学领域:
- 腹部外科 腹部外科
- 胃肠病学 胃肠病学
- 代谢研究研究 代谢研究
背景情况:
- 鲁克斯-en-Y胃绕道 (RYGB) 是一种具有已知的代谢益处的减肥手术.
- 动物研究表明,Roux肢体在RYGB后的葡萄糖吸收增加可能有助于这些益处.
- 关于RYGB对人类肠道葡萄糖吸收的影响的前性临床数据有限.
研究的目的:
- 为了调查RYGB增加葡萄糖吸收在人类患者的鲁克斯肢体的假设.
- 为了评估RYGB手术后肠道葡萄糖吸收的纵向变化.
主要方法:
- 接受RYGB治疗的患者使用正子发射断层扫描/计算机断层扫描 (PET/CT) 成像进行了研究.
- 影像检查是在手术前,手术后3个月和6个月进行的.
- 对葡萄糖的标准化吸收值 (SUV) 在包括鲁克斯四肢和结肠在内的各种肠道段进行测量,用于纵向分析的脏正常化.
主要成果:
- 尽管体重显著下降,但在RYGB后没有观察到Roux肢体葡萄糖吸收的增加.
- 3个月后检测到结肠葡萄糖摄取量的显著增加 (眼皮,肝,西格结肠),并在6个月后维持 (P < .05).
结论:
- 人类早期的术后RYGB与结肠的增加有关,而不是Roux肢体,葡萄糖吸收.

Glucose Absorption Into the Small Intestine
34.9K
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

Glucagon-like Receptor Agonists
828
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
230
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Gastric Emptying
3.3K
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
511
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.

Glucose Transporters
27.1K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
