Former Brazilian President Jair Bolsonaro has posted an update about his health to social media, after undergoing a sixth abdominal surgery that he says is related to a stabbing he endured on the campaign trail in 2018.

On Tuesday, the embattled far-right leader shared a video of himself walking through a hospital corridor, electrodes taped to his bare chest and a walker keeping his steps steady. A team of medical staff flanked him on either side.

“Don’t give up! Let’s move forward, Brazil!” Bolsonaro wrote in a caption alongside the video.

In a second message, he explained that he remained in relative isolation, as his condition is delicate. Following his doctors’ advice, he said he is interacting only with family members and healthcare professionals in an effort to take “maximum caution” during his recovery.

“I remain focused on the recovery process, which from what I understand was the most invasive procedure that has ever occurred,” he said.

Last Friday, Bolsonaro announced he was forced to call off a rally in the northeastern Brazilian state of Rio Grande do Norte after he suffered “severe abdominal pain”, resulting from “a complication in the small intestine”.
