Obesity

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...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

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...

Drug Dosing: Obese Patients

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Summary

Most weight loss surgery apps lack health professional input. A quality stamp from bariatric surgical bodies could enhance patient and clinician confidence in these digital health tools.

Area of Science:

Bariatric surgery
Digital health
Mobile applications

Background:

Smartphone applications (apps) are increasingly prevalent in healthcare.
Weight loss surgery apps are a growing area of digital health tools.
Assessing the quality and professional input of these apps is crucial.

Purpose of the Study:

To review available smartphone applications related to weight loss surgery.
To evaluate the extent of medical professional involvement in the design of these apps.

Main Methods:

A systematic search of major app stores (Apple App Store, Google Play) was conducted.
Keywords related to weight loss surgery were used for app identification.
Apps for non-surgical obesity treatment were excluded from the review.

Main Results:

28 unique weight loss surgery apps were reviewed, with a mean rating of 3.6/5 and cost of £1.89.
92.9% of apps were designed for patient use, categorized into information, support, and record tools.
Health professional involvement was identified in only 42.9% of the reviewed apps.

Conclusions:

The majority of weight loss surgery apps lack input from health professionals.
A "quality stamp" from bariatric surgical bodies could improve app reliability and user trust.
Exploring the use of these apps in patient informed consent processes is recommended.
