The inability to induce vomiting is due to the improper method of inducing vomiting, if you have consumed poisonous food, you need to induce vomiting in time, so that the poisonous food eaten that is not fully digested can be vomited out as soon as possible. It is recommended that you can prepare a large glass of light warm salt water and let the patient drink it. If there is a feeling of wanting to vomit, you can stimulate the posterior wall of the pharynx with cleaned fingers or chopsticks, spoon handles, etc., to induce vomiting as soon as possible, which usually occurs soon. If there is a lot of vomit, the gastric mucosa will be damaged and the electrolyte will be disturbed. Therefore, after vomiting, patients need to pay attention to rest and avoid too much exercise. Diet should be light, easy to digest, fluid or semi-fluid food, such as tomato noodles, green vegetables noodles, millet porridge, etc., to slowly restore gastric function, to avoid causing gastric dyspepsia and so on.
