  • Patent number: 12249426
    Abstract: According to one embodiment, a healthcare support system includes a memory and a hardware processor connected to the memory. The hardware processor predicts a risk value of a disease based on medical checkup data for a medical examinee. The hardware processor sets a reduction target for the risk value of the disease, and sets a plurality of second factors constituting search targets among a plurality of first factors relating to the disease and a search range for each of the second factors. The hardware processor searches, by using a predetermined search method, in the search range for each of the second factors, for a target value candidate of each of the second factors so that the risk value of the disease is brought close to the reduction target.
