Weight Management Cheat Sheet (DRAFT) by

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Pediatric BMI

Perc­entile cut-off value
Classification of BMI
<5th percentile
≥5th & <85th percentile
Healthy weight
≥ 85th and <95th percentile
≥ 95th percentile OR ≥ 30 kg/m2
Adole­scents can have a BMI ≥ 30, but have a BMI-fo­r-age <95th percen­tile. They will still be consider obese


Geneti­c/h­ormonal weight

- Thyroid issues
Dietary factors
- Low intakes of F&V

Weigh­t-loss goals
- Realistic
- Still growing in height
- Should not necess­arily attempt to fully normalize weight
Children at risk for overwe­ight
- Mainte­nance of current weight recommended
- Gradual decline will occur in BMI as the child grows in height due to prolonged mainte­nance
- Gradual weight loss is recomm­ended
Weight loss should not exceed more then 2 lbs per week in children. High rate of weight loss is reserved for 6-11 year olds in the 99th percent title and 12-18 tear olds with ≥ 95 percent tile

Bariatric Surgery

Must have a BMI of 40 or higher
Comorbid conditions BMI 35 or higher
Must had failure of nonsur­gical weight loss
- Restrictive procedures
Restrict the amount of food that enters the SI
- Malabs­orptive procedures
Various sections of SI are bypassed leading to malabs­orption of nutrients
- Combin­ation of restri­ctive and malabs­orptive procedures
- Laparo­scopic Adjustable Gastric Banding (LAGB)
- Roux-en Y Gastric Bypass (RYGB)
- Sleeve Gastre­ctomy (SG)

Laparo­scopic Adjustable Gastric Banding

Often called the band and is a restri­ctive procedure
It works by allowing the stoma to become narrow causing the emptying of the pouch to be delayed. Allowing the individual to feel full and restrict food intake. Band can be deflated when needing higher food intake.
- A small stomach pouch is made in the upper portion of the stomach by a hallow band.
- The hollow band is connected to a port (by tubing its tied to)
- injection of saline solution through the port allows inflation of the band
- Adjusting stomach size
- Increasing stomach size add solution by inject sterile saline through the port filling the band
- Reducing stomach size remove solution gradually over time by repeated adjust­ments
-Preformed laparo­sco­pically
- Less tissue damage, fewer postop­erative compli­cat­ions, shorter hospit­ali­zat­ions, reduced health­-care costs, and shorte­r-p­eriod of post-o­per­ative time.
- Restricts food intake
- 40-50% of weight loss induced
- No cutting of the stomach or intestinal rerouting
-Short hospital stay usually less then 24-hours
- Reversible & Adjustable
- Lowest rate among approved bariatric procedures for early postop­erative compli­cations and mortality
- Lowest rate for micron­utrient defici­encies
- Slower weight loss compared to other surgical procedures
- Higher failing of patients losing 50% of excess body weight compared to other surgical procedures
- Foreign device in body
- Band slippa­ge/band erosion can occue
- Dilation of esophagus can occur if patient overeats
- Strict commitment to postop­erative diet
- Re-ope­ration is the highest

Roux-en Y Gastric Bypass

Known as Gastric bypass. A restri­cti­ve-­mal­abs­orptive procedure
This surgical procedure is known as the gold standard because of its high effect­iveness and durability
The procedure makes a small pouch that bypasses the remainder of the stomach, duodenum, and first section of jejunum. Food digestion is reduced and nutrient absorption is reduced. Allowing restri­ctive food intake
Consum­ption of 6-8 small meals daily. To reduce dumping syndrome risk do 2-4 Tbsp of food at a time.
- Small gastric pouch is made in the upper portion of the stomach
- Distal jejunum is cut and attached to the new small stomach pouch
- Signif­icant long-term weight loss
- Restricts food consum­ption amount
- May increase energy expend­iture (by leading to condit­ions)
- Changes in gut hormones
Reduce appetite
Enhance satiety
- >50% excess weight loss mainte­nanced
- More complex operation compare to AGB and LSG. Can lead to great compli­cation rates
- Long-term micron­utrient defici­encies
- Vitamin B12, Iron, Calcium, Folate
- Must commited to dietary recomm­end­ations and life-long micron­utrient supple­men­tation

Sleeve Gastre­ctomy

Known as the sleeve
This procedure removes the left side of the stomach allowing 85% of the stomach to be removed. This leaves the remaining stomach as a narrow banana­-shaped thublar pouch
- Restricts food
- Signif­icant weight loss
- No foreign objects
- No bypass­/re­-ro­uting of food stream
- Short hospital stay (usually 2 days)
- Changes in gut hormone
Reduce appetite
Enhance satiety
- Non-re­ver­sible
- May cause long-term vitamin defici­encies
- High early compli­cation rate
