Robert Marawa recovering from 3rd heart attack

In a video that he posted on Twitter, Marawa explains that he spent a whole week in ICU.

Marawa says that he drove himself to hospital last week after feeling unwell and that he was admitted to ICU a few hours later.

He remains in the recovery ward of an undisclosed hospital. 

"It's been an unbelievable last couple of days ... on the brink between life and not living," Marawa said.

Marawa has thanked the doctors and medical assistants at the hospital.

"The general staff, the people who are here to ensure our health have been outstanding...some of the best doctors and cardiologists are here.

"I just want to take my hat off to everyone who has been of assistance.”

He also thanked his supporters and called on his followers to go for regular check-ups.

"We don't do this to report to people and make it a public thing. A health journey is a personal journey, but I've always made it public that we need to get our numbers checked.

"I've always made it a public thing that I've had my heart attacks. I need to get back into a regular fitness regime.”

Marawa said doctors were still trying to find out if he had a blood clot that was contributing to the repeated problems. 

The 46-year-old broadcaster has suffered two previous heart attacks.
