Simon Reeve has been inundated with support from his fans after sharing a heart scan and worrying news.
The presenter, 49, revealed that he underwent an ultrasound on his heart.
He shared that the scan took place at Royal Devon Hospital to determine if there had been "any vegetation growth" on the organ after Simon was struck by an "exotic illness".
Simon told fans he had been given the "all clear" and shared his gratitude for his treatment.
He wrote: "My heart(!). Beating and flapping away.
"Final check for any 'vegetation growth' (not a good thing) after exotic illness… all clear was a phew moment.
"Thanks again to @RoyalDevonNHS."
In the comments section, fans were pleased to see Simon was safe and well.
One follower wrote: "So glad you're recovering well. Tropical diseases can be terrifying."
Another commented: "Sounds scary. So glad you're better. Keep doing your investigative thing. It's brilliant and what the world needs."
A third added: "Very glad to hear that Simon. You're way too precious to lose."
A fourth fan shared: "I am so glad you are ok. You and your work is precious. Take care."
"Take care, Simon, we need you back on the box ASAP!" a final person added.
Last year, Simon revealed how he managed to defy the odds after fertility doctors told him and his wife Anya that they had little to no chance of ever having children.
The TV presenter and adventurer knew that he always wanted to be a father, and thought of the role as his life's purpose.
And when he met and first started dating his wife when they were both in their early thirties, Simon knew that if they were going to have children, it needed to be soon.
However, once they started trying, he soon realised that conceiving a child was going to be a much harder task that he initially expected.
After months of trying to conceive a baby naturally, Simon and Anya knew that something wasn’t quite right.
Simon was left horrified when an expert told him that he was ‘basically infertile’
Recalling the moment his world crumbled before him, Simon recalled telling his wife that if he couldn’t have children, he was ‘likely to go mad’.
“I would not be able to have children. It was the starkest of messages: I could hardly take it in,” Simon wrote.
“She told me I had loads of sperm but their morphology was terrible. We’d never heard the term before.
“‘Your sperm are deformed,’ said the expert. ‘They will never be able to break into Anya’s eggs.’”
Simon went on to explain that his he had 0 per cent normal sperm and the fertility experts had also checked his sperm motility.
“My sperm were swimming around in circles, or moving energetically without going anywhere. Ironically enough, considering my day job, they were not good travellers,” he told.
Even with the stark diagnosis, Simon’s wife Anya wasn’t ready to give up just yet.
Anya insisted that her husband led a rather unhealthy lifestyle, and insisted that if he were to make some much-needed changes, then maybe they would have a chance at conceiving a child.
And she was right. The presenter underwent a lifestyle overhaul, and they now have 10-year-old son Jake.
