Weight Loss Surgery Causes Changes In Taste And Appetite

Weight loss surgery has been shown to cause changes in taste and appetite, which may aid in further weight loss by the individual.  Weight loss surgery has become more and more popular as obesity has become an issue in the United States.

A study done on British patients who underwent Roux-en-Y gastric bypass surgery found that the surgery, which makes the stomach smaller and shortens the intestines, almost all had changes.  97 percent of those that underwent the surgery noticed changes in their appetite and 42 percent had changes in their sense of small.

The changes made during the Roux-En-Y procedure.

The website for the surgery explains how the surgery is performed:

Roux-en-Y gastric bypass (RYGB) is a type of weight-loss surgery that reduces the size of your stomach to a small pouch – about the size of an egg. It does this by stapling off a section of it. This reduces the amount of food you can take in at meals. The surgeon then attaches this pouch directly to the small intestine, bypassing most of the rest of the stomach and the upper part of the small intestine. This reduces the amount of fat and calories you absorb from the foods you are able to eat for even more weight loss.

Almost 75 percent of patients had changes in their tastes for certain foods.  A lot of people developed distastes for certain types of meat.  Others developed distaste for pasta or dairy products.  Of those that did develop a distaste, they lost on average about 18 pounds more than those that did not develop any kind of distastes.

The results are concluding that though there is an association, they cannot claim causation.  Other changes that occur in the body after surgery may be the credit to changes in tastes and smells.

    Why can’t they just make a pill that makes food taste bad?

    I had the roux-en-Y surgery just over 10 years ago. The only reason that I had major changes in taste was that certain foods made me sick to my stomach. Eating what you like and getting deathly ill or eating what you can and not getting ill is a pretty simple choice. Learning which foods no longer agreed with me was the hard part. That took nearly 2 years to sort out. Other people that I have known who had the stomach sleeve installed are doing much better. By not bypassing the duodenum, they don’t have problems with different foods like I do. They can still have sweets or anything else they like on occasion. I, on the other hand, cannot. I just wish that the stomach sleeve was in use when I had my bypass. Now, it’s just too late.
