In general, if a fish spike is accidentally swallowed while eating, the risk period is passed after 3 hours without any abnormalities. Under normal circumstances, the body excretes a large amount of stomach acid for digestion after eating, so a fish spike swallowed in the stomach can be digested and discharged into the intestines in 2-3 hours. If the fish spike is small, it is usually not dangerous and does not cut the throat after swallowing. 3 hours after the patient has no other symptoms such as abdominal pain, the fish spike has been digested. If the fish spike is larger, it may get stuck in the throat, and even if swallowed into the stomach, it may cut the throat and cause severe stinging pain, and the patient may feel tingling in the neck and chest, which is dangerous and may lead to pharyngeal staining, and in severe cases, laryngeal edema causing asphyxia. Therefore, it is recommended that patients should go to the ENT department of the hospital for further examination. In daily life, patients should pay attention to chew slowly when eating and prohibit overeating so as not to cause discomfort by mistake.
