Obesity EpidemicObesity Epidemic

• World epidemic - 1.7 billion people

• BMI >35 & >40 showing rapid growth

• Rise in obesity > rise in comorbidities

• Comorbidities > 2.5 million deaths per year

• Morbid obesity - reduction in lifespan

Buchwald et al. Jama 2004Buchwald et al. Jama 2004

Obesity EpidemicObesity Epidemic

• T/t :

• Diet therapy alone is ineffective in long term .

• Currently, there are no effective pharmaceutical agents to treat obesity, especially morbid obesity

Obesity in India

• Morbid obesity - 10% of the country's population.

• Unhealthy, processed food has become much more accessible in global food markets.

• Indians are genetically susceptible to weight accumulation especially around the waist.

• A SNP (single nucleotide polymorphism) GENE named rs12970134 to be mostly associated with waist circumference

LACK OF PHYSICAL ACTIVITY& MEDICAL REASONS

LIFESTYLE CAUSES

• Calculated as follows: Weight(kg)/Height(m2)

• Mortality lowest = BMI < 25kg/m2

TREATMENT OF OBESITY

2.EXERCISE

3.BEHAVIOURAL/LIFESTYLE MODIFICATION

4.MEDICAL / DRUGS

5. SURGERY

Medical Treatment of Obesity

Diet – low in calories, fat and carbohydrates (1200 cal/ day)

Exercise– 40 minutes 5 times per week

Behavior Modification – eat 3 sensible meals per day, avoid snacking

Drugs/Prescription medications-Stimulants/appetite suppressants

– Antidepressants (Meridia®)

– Reduce fat absorption (Orlistat)

Disadvantages of medical treatment:

Most patients (95-97%) regain weight that was lost within 2-5 years following diet or drug treatment

The average amount of weight loss is relatively small – 10-20 Kgs

Drug therapy may be associated with severe complications

Disadvantages of medical treatment:

Most insurance companies do not cover costs

• Very difficult to maintain these programs in the long term

• “Yo-Yo” effect leads to significant weight fluctuations

Surgical Treatment of Obesity

• Surgeons who specialize in treating obesity or the Dangerous Triad are known as Bariatric or a Metabolic surgeon.

• Bariatric surgery leads to significant and long lasting irreversible weight-loss alongwith resolution of comorbidities in severely obese patients

Bariatric and Metabolic Surgery

• Bariatric Surgery - from the Greek “baros” meaning “weight”, is synonymous with weight loss surgery.

• Metabolic surgery - be defined as “a set of GI operations used with the intent to treat diabetes ("diabetes surgery") and metabolic syndrome. (X- syndrome )”.

Indications for SurgeryIndications for SurgeryNIH Guidelines

BMI > 35 WITH 1 OR MORE COMORBID CONDITIONS (DM / HTN )

BMI > 40 WITHOUT ANY COMORBID CONDITIONS

PREVIOUSLY FAILED WEIGHT LOSS ATTEMPTS ( e.g, non-surgical interventions, diet control, behavioral modifications, exercise )

Indications for SurgeryIndications for Surgery

• Age > 18 or < 65• Failure of diet > 6 months• Obesity history > 5 years • Low risk for surgery• No endocrinological disease• Psychologically sound

NIH Consensus Conference NIH Consensus Conference Ann Intern Med 1991Ann Intern Med 1991

Goals of Surgery

• Effective: Loss > 50% of Excess Weight

• Low operative morbidity & mortality

• Well tolerated

• No long term complications

5 TO 6 PORTSThe benefits are:

•Less Pain•Quicker recovery and return to normal activity•Fewer complications•Less noticeable scar•Shorter hospital stay

Laparoscopic Procedure

Surgical ProceduresSurgical Procedures

• 1.RESTRICTIVE PROCEDURESES

• Restrictive surgeries shrink the size of the stomach which reduces the amount of food it can hold. This makes you feel full when eating much sooner than you did before surgery

–Gastric Banding–Sleeve Gastrectomy–-Gastric Plication

2. MALABSORPTIVE PROCEDURES

Malabsorptive surgeries rearrange and/or remove part your digestive system which then limits the amount of calories and nutrients that your body can absorb.

–Biliopancreatic Diversion• Scopinaro• Duodenal-Switch BPD

3. HYBRID PROCEDURES

– When surgery combines both restrictive and malabsorptive component, it is known as a “combination” procedure.

– Roux-en-Y Gastric Bypass / Banded– -Mini Gastric Bypass

Bariatric Procedures Performed Today

Restrictive procedure

We reduce the size of stomach 75%

How does a sleeve work?One of the mechanisms involved in weight loss observed after the LSG is the dramatic reduction of the capacity of the stomach.

Ghrelin An orexigenic (appetite-stimulating) peptide hormone mainly produced in the fundus of the stomach, is supposed to be involved in the mechanisms regulating hunger .

MALABSORPTIVE PROCEEDUREBilio-pancreatic diversion

Scopinaro SG with DS

HYBRID PROCEDURE / COMBINATION

We do restriction by making a small stomach pouch, alongwith create a malabsorption by bypassing the BPD limb.

GI HORMONES AS INCRETINS & ANTI INCRETINS

Mechanism of Incretin action action

PROPOSED THEORIES FOR IMPROVED GLYCAEMIA

(A) RAPID HINDGUT DELIVERY HYPOTHESIS

• Rapid delivery of ingested nutrients to lower bowel due to intestinal bypass leads to stimulation of L cells , ( distal i leum & colon ) which in turn results in increased secretion of incretin hormones & improved glucose homoeostasis.

•Proximal nutrient related signals that are transmitted from the duodenum to the distal bowel by neural pathways leads to increased Incretin secretion.

PROPOSED T(B) FOREGUT HYPOTHESIS HEORIES FOR IMPROVED

GLYCAEMIA

•The proximal small intestine (foregut / BPD limb ) is excluded resulting in reduction in secretion of Anti – incretin factors ( diabetogenic hormones) in response to absence of nutrients in the fore gut.

•This leads to improved glycaemia. &•Decreased Intestinal Glucagon synthesis

.

Benefits of Weight Loss Surgery

Significant weight loss• Lower cholesterol – D-30• Lower blood pressure• Improvement of Type II diabetes –D-1

• Improvement of cardiovascular health• Relief of sleep apnea• Relief of digestive problems –GERD• Decreased joint pain• Improved mobility

• Improved self image•
