Nintendo president Iwata addresses concerns over recent health problems

Nintendo president Satoru Iwata took to Twitter today to address worries over his health following a major operation earlier this year.

The Nintendo head first caused concerns when his surgery to remove a growth found in his bile duct was followed by a noticeably more frail appearance. Iwata would go on to skip June's E3 event on the advice of his physician.

The Nintendo president now confirms his weight is stabilizing.

"I saw many worried comments over how thin I've become," wrote Iwata in a statement to Twitter followers. "The truth is that after a major operation, I lost weight, but during these past two and a half months, thankfully my weight has stabilized, and I'm progressing well. I would truly like to thank my doctors, the hospital staff, and everyone who has assisted me."

Last month, Iwata said he felt healthy enough to fully return to work despite the effects of the operation. Earlier this year he talked about his surgery. "In general, it is said that a bile duct growth can be difficult-to-treat, partly because of the difficulty of detecting it early. In my case, luckily, it was detected very early and I had no symptoms. I was counseled that removal at an early stage would be the desirable medical option. Therefore I had surgery last week, and I came through it well, as predicted."
