sometimes the scar tissue causes the stoma to narrow significantly, making it difficult for food or even liquids to pass through into the small intestine. In some cases, the opening can close completely. This is known as a stricture.
Strictures after a gastric bypass are not that uncommon. They can be serious, however, because obviously you have to be able to get food and liquids in. The most common symptom of a stricture is vomiting after eating or drinking. Now, vomiting after eating is not that unusual after a gastric bypass, especially in the early days after surgery. Eating too much, eating too fast, or not chewing well enough can all cause vomiting. Many people cannot tolerate certain foods anymore after a gastric bypass, such as sugar or fatty foods. Eating these foods may cause vomiting. But if you vomit every time you eat, especially if you are eating slowly and making sure to chew well, it may be a sign of a stricture.
