Summary: Summary Abdominal adiposity causes disability and death especially through DM andamp; CVD risk.
Adipokines mediate much of this effect through a complex network of mechanisms on several organs.
Recognition and treatment is imperative. Lifestyle is key. Drug treatment to affect causes and consequences of abdominal adiposity is also needed.
Identifying patients at elevated cardiometabolic risk: Identifying patients at elevated cardiometabolic risk Many patients at high CV risk can be identified by a simple waist circumference measurement in conjunction with other routine cardiometabolic markers
High waist circumference, a marker of abdominal obesity:
is an independent CV risk factor
is independently associated with each of the other components of the metabolic syndrome Waist circumference measurement should become a routine part of global assessment of metabolic and cardiovascular risk and should be integrated into standard clinical practice Pouliot MC et al.

Assess and Manage Obesity: Assess and Manage Obesity
If you only have 15 minutes….
Tell your patients that you are concerned about his/her weight.
You can start this discussion by saying, 'I’m concerned about your weight because I think it is causing or will cause health problems for you. Do you think your weight is causing problems for you?'
Advise you patient to lose weight.
First ask, 'Have you ever tried to lose weight?' Praise your patient’s efforts, and reinforce that weight management through increasing physical activity and watching what one eats is good for health.
If your patient is interested in weight management, share handouts for him/her to read at home.
Some handouts that you can share are the Graphing Your Weight Gain chart, the Eating Pattern questionnaire, and the Weight Loss Questionnaire. Assessment and Management of Adult Obesity: A Primer for Physicians, AMA
