Most make them about the size of a lemon. Some surgeons do a micropouch. Mine was a micro pouch and about 10cc. The cottage cheese test is a way to see what size your pouch is.
The Cottage Cheese Test
- Purchase a container of small curd low-fat cottage cheese.
- Begin the test with a full container of cottage cheese, and perform the test in the morning before eating anything else. This will be your breakfast on that day.
- Eat fairly quickly until you feel full (less than five minutes). Note that the small soft curds do not require much chewing. You are eating rapidly so you will fill the pouch before there is time for any food to flow out of it. After eating your "fill" of cottage cheese, you will be left with a partially eaten container that has an empty space where cottage cheese used to be.
- Measure the volume of cottage cheese you have eaten by filling a two cup (16 fl.oz.) measuring cup with water. Pour water into the container of cottage cheese until the water level rises to the original top level of the cottage cheese.
- The amount of water poured into the container is the functional size of your pouch.
Dr. Flanagan's research indicates that the average volume of the mature stomach pouch, measured by this method, is 5.5 ounces (163 ml). Additionally, he reached the conclusion that, "sizes ranging up to 9 ounces have NO IMPACT on the person's success in weight loss". This means that unless your pouch holds a greater volume than 9 ounces (267 ml), the exact size of your pouch is not a critical factor in whether or not you can lose excess weight and then manage your weight as time progresses.
