#hypothermia, #cold-related illness, #cold wave, #body temperature, #core temperature, #frostbite, #winter health, #hand tremor, #body tremor

Hypothermia refers to a drop in core body temperature to 35°C or below. The lower the body temperature falls, the more dangerous the condition becomes, and in severe cases it can lead to cardiac arrest. It can occur with prolonged exposure to extreme cold or cold environments, and extra caution is needed when alcohol has been consumed. If hypothermia is suspected, please call 119 immediately or go to a hospital.

Liver transplantation is an operation that replaces a liver that has lost its function with a healthy liver, and it is one of the treatment options for several serious liver diseases, such as liver failure caused by cirrhosis and liver cancer. Since it was first performed in Korea in 1988, advances in technology and medication have led to more than 1,500 transplants a year at present, and the overall surgical success rate is reported to be about 90 to 95%. Liver transplantation is an important decision for both the recipient and the donor, so please discuss it thoroughly with your treating physician before making a decision.
