Why Surgery for Weight Loss?

If you are struggling with obesity, the Emerson Health Center for Weight Loss in Concord, Massachusetts, is here to help. Deciding how to lose weight is complicated. For many people who are significantly overweight, improving diet and increasing exercise do not result in desired, or long-term success. There are options to help people successfully lose weight. 

Supporting patients throughout New England, we know what it is like to suffer from this disease. We also understand that the decision to undergo weight loss surgery isn’t just about improving your health – it’s about changing your life.
