The true extent of Britney Spears' medical issues are reportedly "far more complicated"

than many people realize.  An inside source brought these findings to light during a chat with Page Six.

The insider in question is part of Britney's close circle and warned about

the implications of her complex medical needs.

They warn "no one outside a very small conservative circle knows exactly what Britney's medical condition is."

"If people knew Britney's real medical condition,

I think it would reveal that her mental problems are much more serious than people realise."

However, insiders agree that

"regardless of her mental state, she shouldn't necessarily be under a guardian.

There are less drastic ways to handle it.
