International classification of adult weight categories:

  • BMI under 18.5 – underweight
  • BMI 18.5 – 25 – normal weight
  • BMI 25 – 30 – overweight

    • Obese class I – BMI 30 – 34.99

Health & Psychological Conditions

Issues that will be assessed by our expert bariatric team to make a final decision whether the weight-loss surgery is safe and appropriate tool for you, will include your –

  • Medical history. General health condition, previous surgeries, diseases, medications, family medical history will help physicians prevent risks and choose the most effective and safe type of weight-loss surgery for you.
  • Dietary habits, lifestyle and your previous weight loss attempts.
  • Physical activity or inactivity. Physical activity is definitely related to improved health and higher energy levels, while physical inactivity might be related to the development of obesity. If you consider the weight-loss surgery, you should understand the relationship between physical activity and lifelong management of obesity.
  • Psychological factors. After the weight loss surgery you will face dietary restrictions, you will have to change permanently your eating and dietary habits. More likely you will have also to review your physical activities and find your own way to a healthier and happier you! These changes may lead you to altered and new feelings and sensations, new behaviours, probably to some relationship change. Before making a final decision about the surgery, you and your surgeon should be sure for your personal consciousness and your ability to involve in the weight-loss process in long-term. There are some mental health conditions that may contribute to gain weight and also make it more difficult to maintain the health benefits of weight loss surgery.

Personal Commitment

Weight-loss surgery should not be considered a magical solution itself. One of the most important issues for a lifetime success after your weight loss surgery is personal commitment to follow your surgeon’s guidelines for diet, lifestyle change and daily physical activities. It is critical to assess your weaknesses already upfront the surgery to be able to really change your daily habits.
