# I Built a Real-Time AI Medical Assistant After Losing a Dear Person to a Preventable Diagnosis

By Okafor Ogbonna Pascal Losing a dear person is never easy. But losing someone to a condition that could have been caught early — that stays with you differently. Someone close to me passed away from undetected kidney failure. For years, they had been living with hypertension that went unnoticed. Not because they were careless. But because access to basic primary healthcare in Nigeria is not a guarantee, it is a privilege. By the time the tests were run and the diagnosis was clear, it was too late. They didn't have to die. If they had access to early detection — even something as simple as someone who could explain the symptoms, flag the warning signs, and say "please see a doctor urgently" — they might still be here today. That loss never left me. And when I discovered the Gemini Live Agent Challenge, I knew exactly what I had to build.
