What are Dionne’s 5 Bariatric Body Types?
Apple Ascites Apple Pannus Pear Adduction Pear Abduction Gluteal Shelf
What is Apple Ascites?
Body fat accumulates anteriorly and centrally on the torso
As per Quizlet:
- Have a high waist to hip ratio
- Have significant difficulty in tolerating flat supine and prone postures. Usually
have several pillows under the head end of the bed to achieve semi-fowler
position to augment breathing. - Hypertrophy of accessory muscles of respiration
- Has an immobile chest, immobile umbilicus
What is Apple Pannus?
Body fat accumulates around the torso, but with a flap over the legs
As per Quizlet:
- Have high waist to hip ratio
- Patient has a mobile umbilicus
- Variable supine tolerance
- May tolerate prone
What is Pear Abducted?
Body fat accumulates on the inside of the thighs
Lowered COG
Issues with toileting and moisture accumulation
As per Quizlet:
- Have a very low waist to hip ratio
- Majority of tissue is below belt line and femur is in abducted posture
- Severely painful knees due to Valgus stress
- Move from supine to sit via long sitting and avoid log rolling
What is Pear Adducted?
Body fat accumulates on the outside of the thigh
Better at rolling than Pear Abducted
Lower COG
As per Quizlet:
- Low waist to Hip ratio
- Lower extremities are adducted and in-line with the body
- Move from supine to sit via long sitting or may seek rolling technique
People with Pear (Abducted/ Adducted) body types have a difficult time rolling
Abducted
What is Gluteal Shelf?
Body fat accumulates in the gluteal region
They have a hard time sitting and laying down
As per Quizlet:
- Mixed Waist to Hip ratio
- Excessive posterior tissue in gluteal region
- Limited Supine tolerance
What are orlistats? What’s wrong with them?
Medication that prevents the absorption of 1/3 of dietary fats, however they may limit absorption of nutrients we need. Side effects include liquidy stool, gassy, discomfort (like IBS)
What is sibutramine? What are some of the problems with them?
Medication that increases satiation. They affect the parasympathetic nervous system. They may cause HTN and other problems.
