As far as I remember, SQLite uses the type only for input/output. Internally, everything is stored as text (that’s why you can also store text in an int-field if you want). So no, it shouldn’t remove any data, because it’s only a superficial change.
No guarantees though, it’s been a while since since I last worked with SQLite 😉
This page explains SQLite’s typing system nicely.
