Are there health risks associated with sleeping in a height tent?

No there are absolutely no health risks associated with sleeping in one altitude tent.
There are countless places in the world where people live full-time at height.
For example, think of the many ski areas in the Alps. The use of the height tent is the same as sleeping in the Alps.

If it is 'OK' for your doctor to take the plane then you can also use a height tent.
