Capper left the country on 2 April as part of an expedition to raise funds for Rare Diseases South Africa.

The cause is said to be close to her heart, as her young daughter has cystic fibrosis.

The mother of two is recovering at a Kathmandu hospital and is in "good spirits".

@_nicolecapper is recovering well and in good spirits.
