Speculating on someone's health without proper medical expertise and examination would not be appropriate.
It's essential to remember that public figures, like any individual, have a right to privacy regarding their health. Concerns about someone's health should be addressed by medical professionals who have the necessary expertise and access to the person's medical history and current condition.
Stress can have adverse effects on a person's physical and mental health, but making assumptions or predictions about someone's health based solely on their public actions or behaviors is not a valid approach.
If you have concerns about an individual's health or well-being, it's best to encourage them to seek appropriate medical advice and support from qualified professionals.
