When does your bmi become non critical and you can discharge yourself as an in-patient?

BMI hospitalization: Your question is a bit difficult to understand. Bmi stands for body mass index and is a function of your height and weight. If you are very obese or very underweight the critical nature of its value would depend on other health factors. When you can leave a hospital is a different factor that is unrelated to bmi. It should relate to when your physicians feel that you are ready to be discharged.
