体調を崩しかねないので (could lead to ill health, so...)

Grammar & Usage

fixed expression (verb phrase + conjunction)

neutral to slightly formal

How it works

This expression uses the verb stem (連用形) of 崩す (to get out of condition/health) + かねない (kanenai), which indicates a strong possibility of an undesirable outcome. の (no) functions as a nominalizer, and で (de) as a connective particle, meaning 'because' or 'so', indicating a reason for a subsequent action or warning. It suggests a potential negative consequence as a reason for a cautionary statement.
