Pharmacokinetics in Obese Patients: Drug Absorption and Distribution01:25

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

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...

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Summary

Metabolic bariatric surgery is common for obesity and diabetes. Sleeve gastrectomy (SG) has significantly increased in prevalence since 2008, becoming a leading procedure.

Area of Science:

  • Bariatric surgery
  • Metabolic surgery
  • Gastrointestinal operations

Background:

  • Metabolic/bariatric surgery is frequently performed for morbid obesity and type 2 diabetes.
  • Periodic assessment of surgical procedures is necessary.

Purpose of the Study:

  • To assess the numerical status and procedural distribution of metabolic/bariatric surgery.
  • To analyze global and regional trends in these procedures.

Main Methods:

  • Email questionnaire distributed to leadership of 50 IFSO nations.
  • Collected data on operation numbers, surgeon numbers, procedure types, and trends (2003-2011).
  • Analyzed data globally and by IFSO regions (Europe, USA/Canada, Latin/South America, Asia/Pacific).

Main Results:

  • 84% response rate; 340,768 procedures and 6,705 surgeons globally in 2011.
  • Most common procedures: Roux-en-Y gastric bypass (RYGB) 46.6%, sleeve gastrectomy (SG) 27.8%, adjustable gastric banding (AGB) 17.8%.
  • SG showed a marked increase (0% to 27.89%), while RYGB decreased and AGB showed an initial rise followed by a steep decline.

Conclusions:

  • Periodic surveys enhance understanding for physicians treating morbidly obese patients.
  • Sleeve gastrectomy (SG) has significantly increased in prevalence.
  • Global trends show a shift in procedure popularity.
