Patient history
Note the following information concerning the patient’s weight history:
- Cause of weight loss: bariatric surgery or lifestyle changes
- Maximum weight and BMI (at any point in life), current weight and BMI, and the decrease in BMI points
- Any mechanical issues during sports or other physical activities
Furthermore a thorough preoperative assessment including prior medical history is fundamental. Go to the chapter “Preoperative assessment” to read more.
Physical examination
With the patient standing: Inspection with the arms abducted 90 degrees and the forearms extended as well as when adducted close to the body. Pinch the medial part of the arms to inspect excess skin as well as the laxity and quality of the skin.
With the patient laying down: Flexion of the shoulders and elbows in 90 degrees and assessing the previous markings in relation to the expected stress on the skin after removal of the excess skin.
