 Death caps have been reported to taste pleasant . This , coupled with the delay in the appearance of symptoms — during which time internal organs are being severely , sometimes irreparably , damaged — makes it particularly dangerous . Initially , symptoms are gastrointestinal in nature and include colicky abdominal pain , with watery diarrhea , nausea , and vomiting , which may lead to dehydration if left untreated , and , in severe cases , hypotension , tachycardia , hypoglycemia , and acid – base disturbances . These first symptoms resolve two to three days after the ingestion . A more serious deterioration signifying liver involvement may then occur — jaundice , diarrhea , delirium , seizures , and coma due to fulminant liver failure and attendant hepatic encephalopathy caused by the accumulation of normally liver @-@ removed substance in the blood . Kidney failure ( either secondary to severe hepatitis or caused by direct toxic kidney damage ) and coagulopathy may appear during this stage . Life @-@ threatening complications include increased intracranial pressure , intracranial bleeding , pancreatic inflammation , acute kidney failure , and cardiac arrest . Death generally occurs six to sixteen days after the poisoning .
