Eddie Van Halen, 57, has undergone emergency surgery to treat an intestinal disease, promoting his rock band to postpone its tour to 2013.

The news was announced on the group's website on Thursday, August 30, weeks after Van Halen ended the first leg of a reunion tour in the United States. The group says it has postponed its upcoming three concerts in Japan, which were set to take place in November. The first, in Osaka, has already been sold out.

"Eddie Van Halen underwent an emergency surgery for a severe bout of Diverticulitis. No further surgeries are needed and a full recovery is expected within 4 - 6 months," the message said. "Van Halen's scheduled November 2012 tour of Japan is currently being rescheduled and the band looks forward to seeing and playing for their fans in 2013."

In diverticulitis, pouches in the intestine, usually the large one, become infected or inflamed due to trapped stool, according to the U.S. National Library of Medicine. The disease can lead to complications such as holes in the colon if left untreated. It is relatively common, especially among people over the age of 60 whose diet does not include enough fiber.

Van Halen, which rose to fame in the 1980s, had been on the road for months this year. Eddie, the group's guitarist, his son and bassist Wolfgang, and brother, drummer Alex, reunited with the band's original singer David Lee Roth earlier this year and in February, began a North American tour to promote their new album, "A Different Kind of Truth." It is the group's first major record with the singer in 28 years.

Van Halen had announced in May that a second leg of the tour would be postponed so they could "put more time into the planning" of the remaining North American concerts. The final gig took place on June 26 in New Orleans. Van Halen said the dates of the second leg would be rescheduled and that the tour would "probably continue" into 2013.

The group also denied reports that speculated that one of the musicians may be ill. Eddie, who has battled health problems in the past, performed his trademark guitar solos during the recent concerts without showing signs of fatigue. In 2007, Van Halen reunited with Roth for a tour and postponed several dates after Eddie became ill.

Eddie has undergone rehab for substance abuse and had hip replacement surgery in 1999. In 2000, he was diagnosed with tongue cancer. Doctors removed parts of his tongue and he declared himself cancer-free in 2002. He revealed to Esquire magazine that the disease returned twice in 2011, promoting more surgery, and that he undergoes routine checkups several times a year.
