Bones swallowed have no matter, there is no effect on health with the size and shape of the bone, etc., can be analyzed from the following aspects: 1, the size of the bone: if the bone volume is relatively small, and rounded shape, no sharp edges, brittle texture, generally will be broken down by gastric acid, gastric acid has a strong corrosive effect, will not affect the body; swallowed bone volume is relatively large should be alert to whether it will be stuck in the 2. Bone shape: If the swallowed bone has a smooth appearance and does not cause damage to the mucosa when it reaches the stomach through the esophagus, there is generally no discomfort; if the swallowed bone has an uneven appearance with obvious raised angles or sharp angles, it may cut through the mucosa and cause damage, and in serious cases, it may lead to esophageal perforation.
