As this game involves rigorous physical activity and joints manipulation, minor injuries and illness do occur to the players. However, some injuries may be severe if a player does not play with careful measures and concentration.
The International Judo Federation has very strict rules regarding the handling of the cases of medical treatment of the injuries because the nature and cause of the injuries may affect the award and ending of the match.
Unless the mat judge allows, the medical team is prohibited from entering into the playing area.
A contestant once opts for medical treatment automatically forfeits the match.
If a contestant becomes unconscious on the floor, without the application of choking technique, then the medical team is bound to attend the case even if the contestant has not opted for it.
Nose bleeding cases do not get medical attention. Contestants have to use cotton balls in the nostrils by themselves.
