Prince Mahidol Adulyadej was beset with kidney problems during his last year at medical school. Despite chronic health problems, he managed to graduate with honours. Immediately after his finals, he suffered from acute appendicitis requiring immediate surgery. As soon as he was well enough to travel, he and his family went to Europe again for an extended stopover, returning eventually to Siam in 1928 and taking up residency at Sra Pathum Palace. Prince Mahidol died on 24 September 1929 at Sapathum Palace.
