If you get dizzy after eating conch, it is usually due to a certain food reaction after eating seafood. The dizziness after eating conch can be relieved by the following methods: 1. The patient can go to the hospital to perform gastric lavage, usually conscious, and can drink 50ml of saline or warm water in several times, with the total amount of gastric lavage being 3000-5000ml. 2. For example, mannitol can be used for enema to clean out the snails that have not been completely digested in the intestinal tract. Diuretics, such as hydrochlorothiazide or furosemide, can also be applied to enable the toxins in the conch to be metabolized in the body as soon as possible.
