Grammy Award-winner Gloria Gaynor’s disco anthem “I Will Survive” reached number one on the Billboard Hot 100 charts in 1979, selling over 14 million copies worldwide. Forty years after the release of her iconic track, Ms. Gaynor, who has struggled with osteoarthritis - a type of degenerative joint disease that nearly crippled her for years - is still surviving.

“The pain is excruciating. Debilitating. It makes you feel older than you are,” says the singer, who has had both knees replaced and a dozen metal rods placed in her spine as a result of the disease. Today, she says, “I feel that I have survived osteoarthritis, and I will not let it stop me.” Ms. Gaynor will release a new gospel album this year, entitled Testimony.

Osteoarthritis (OA) occurs when the cartilage that covers and protects bones to prevent them from rubbing together becomes damaged or deteriorates. The disease is most often diagnosed in older people and currently affects over 30 million people in the U.S., with women over the age of 55 at a higher risk of developing the disease than men.

“It is the most common form of arthritis that we see,” says Pfizer’s Chief Patient Officer, Dr. Freda Lewis-Hall, explaining that injury, overuse, obesity, weight gain, and genetics can all contribute to the development of the condition.

What can individuals who are living with OA do to help ease their discomfort? “First, a healthy diet and healthy body weight as well as routine, moderate exercise,” says Dr. Lewis-Hall, adding, “these can help slow down the development of the disease.”
