In February 2022, Mphatso and his father traveled to Blantyre so Mphatso could undergo tests to receive an official diagnosis. The doctors and specialists at Mercy James determined Mphatso suffers from arteriovenous malformations (AVMs), which happens when a group of blood vessels form incorrectly. The arteries and veins are tangled and form direct connections instead of connecting through capillaries as they should to bypass normal tissue. It was discovered that Mphatso had two veins feeding the growth.
