If only 1-2 leeches are eaten into the stomach, there will be no danger or bad situation because leeches cannot survive in the human stomach, and the stomach acid in the stomach is strongly corrosive and acidic, which can corrode the locusts. The leech cannot continue to survive in human body temperature above 37℃ and acid-base balance state, so if only 1-2 locusts are eaten into the stomach, only close observation of the situation is needed. If there is no gastrointestinal and abdominal discomfort, no special treatment is usually needed. But if you accidentally accidentally eat leech in large quantity, you should take the emetic method, that is, drink a lot of warm water, drink more than 5000-8000ml and take the way of picking throat to vomit out all the accidentally eaten locusts, which can relieve the pressure of gastrointestinal tract and avoid food poisoning. You can also apply the catheterization method, that is, enema with mannitol, to remove part of the leech absorbed by the digestive tract in the intestine, and you will be out of danger.
