Lithium carbonate can cause digestive system effects if eaten by normal people, resulting in abdominal pain, diarrhea, bloating, nausea, vomiting, constipation and other digestive discomfort and digestive absorption dysfunction of the digestive tract. If a normal person takes lithium carbonate orally, it will also cause changes in the blood system, such as an increase in white blood cells. Neurological adverse reactions are particularly pronounced, with fine tremor of the hands, disorientation of the cone system and extrapyramidal system, atrophy, weakness of the limbs, drowsiness, coma, or even lethargy, blurred vision or hyperreflexia of the tendons and hyperreflexia of the extremities. For the adverse reactions of the mental system, if normal people take it, it will lead to mania, depression or alternating episodes of mania and depression, so normal people who take lithium carbonate need to go to the hospital immediately for gastric lavage and detoxification treatment.
