A day after an operation to relieve pressure on his brain, former US president Jimmy Carter is "up and walking", his pastor has revealed.

The news was broken when Rev Tony Lowden of Maranatha Baptist Church visited Carter at Emory University Hospital in Atlanta on Wednesday. The pastor added that the 95-year-old was in good spirits following the operation.

The surgery was performed to treat a subdural hematoma. This is a condition that arises when blood collects between the skull and the surface of the brain. There were no complications during Carter's procedure, Carter Center spokeswoman Deanna Congileo said.

The condition was the result of a number of recent falls for Carter. He had a hip replacement following a fall this spring, and after a further two falls in October, Carter was confirmed to have hit his head on at least one occasion.

Carter served one term for the Democrats between 1977 and 1981 before being defeated by Republican rival Ronald Reagan in 1980. Since leaving the White House, the 95-year-old has lived longer than any other president.

After being diagnosed and subsequently recovering from cancer in 2015, as per the Daily Mail, Carter said that he came to terms with his own mortality: "I assumed, naturally, that I was going to die very quickly."

"I obviously prayed about it. I didn't ask God to let me live, but I asked God to give me a proper attitude toward death. And I found that I was absolutely and completely at ease with death," he continued.

"It didn't really matter to me whether I died or lived. Except I was going to miss my family, and miss the work at the Carter Center and miss teaching your Sunday school service sometimes and so forth. All those delightful things.

I said a prayer about it I didn't ask God to let me live, I found that I was absolutely and completely at ease with death."

For now, the oldest living president in the US remains in hospital for observation, and it's not known when he will be released.
