Weakness becomes more meaningful when it appears together with Weakness, because that combination changes which diagnoses move higher on the differential and which ones can be deprioritised. That is why this page now reinforces the diagnostic path with direct links to the strongest canonical symptom and condition hubs, so Google and users can see a clearer entity relationship instead of another standalone FAQ fragment.
