The Delhi Public School,
Subject: Leave for vomiting and loose motion
I’m writing this leave application to let you know that I’m severely sick. I’m suffering from food poisoning which is leading to vomiting and loose motion. I’m not able to digest any solid foods. My doctor has prescribed medicines and complete rest. So please understand my health condition and consider my leave application. It would be a great help for me to recover as soon as possible and resume classes.
