Many of us wish that we had the time to eat healthily, to exercise more often and to pay closer attention to the needs of our bodies.  Many more of us are unhappy with the way we look.  Fortunately for the majority of the world's population, weight and dietary problems can be corrected through the helpful advice of your health practitioner, nutritionist or doctor and taking better care of ourselves can be the sole difference between healthy and overweight.  Sadly there are some who try their best to maintain a healthy diet and exercise regime but are still unable to lose weight, and if these people are also clinically obese this can lead to a very serious health problem.  Obesity puts pressure on the body's organs and joints, has been linked to heart disease, cancer and arthritis, and can generally encourage social stigmatization and feelings of low self-esteem.  This is why bariatric surgery exists - to aid those who are unable to control their weight themselves and to help them to get back to a healthy, controllable state both in body and mind.
