• The actor who played Hagrid in the "Harry Potter" films has passed away.

• Prior to his death, he said he couldn't walk because of arthritis.

• Symptoms ofOsteoarthritis can get worse over time

The actor who played Hagrid in the "Harry Potter" movies passed away on Friday.

The actor starred in all the Harry Potter films. He appeared in two James Bond movies and a TV show. His death was confirmed by his agent.

He said he was disabled and in constant pain before he died. He told the Daily Star that he had a type of arthritis called osteoarthritis.

The condition limited the actor's mobility. He had a walking stick and a wheelchair.

Coltrane said that he was in constant pain. I had an exploratory operation and they found I had no left knee. It's no longer functioning.

In 2020, he told the Daily Express that he was fighting pain 24 hours a day when he was filming "National Treasure."

Excess weight, diabetes, and older age are some of the risk factors for osteoarthritis.

Mild symptoms such as pain in the hands, knees, hips, neck, or lower back can be signs of the disease. Osteoarthritis can cause a change in the shape of bones as the disease progresses.

The correlation between osteoarthritis and premature death is still being studied. According to the Arthritis Foundation, people with osteoarthritis may have trouble exercising or walking, which may cause weight gain or increase the risk for chronic disease. There is an increased risk of falling due to the disease.

For the 20th anniversary of the "Harry Potter" franchise, Coltrane reflected on the franchise's legacy and his death.

"My children's generation will show them to their children, so you could be watching it in 50 years' time." I won't be here but Hagrid will.
