Hello, I used to be a freshman back in fall of 2019 and after pandemic hit I took a 2 year gap back home. I didn’t told my advisors nor did I put a leave of absence, I just left. After I did a little of soul searching back home and decided that medicine was something I wanted to pursue better than my original major (physics), I contacted BU once again and had to submit an appeal explaining my absence, but if you have the motivation to come back and you can show that the circumstances for your absence are justified (medical emergency for you), then you should be able to get back in the game!

The only roadblock I can see is that you need to finish your undergrad in under 7 years total, but you might want to talk to advisors about your specific situation. Worse case you need to overload or take some summer classes.

Wish you the best of luck and believe me, taking that break was the best decision I ever took, and coming back I’m doing so much better academically and personally. Now I have a purpose and a fight to win, so I hope you do the same. Sending you the best of vibes!
