A mother-of-three died of a blood clot 17 days after undergoing breast enlargement surgery in London.
An inquest into the death of Louise Harvey, 36, of Norwich, was opened in Norwich on Tuesday and adjourned for a full hearing on March 26.
A JustGiving page has been set up to raise money to help support her children.
Mark Hutson, who set up the page, said: “Louise Harvey sadly passed away recently after a blood clot formed in her body.
“It has been a shock to us all that this beautiful, young, devoted mother-of-three has been taken away from us so early and without warning when she had so much to live for.
“We have received an overwhelming response from family and friends offering their condolences and support and would like to contribute in some way to ease the suffering her death has caused.”
It said the money raised would help provide a “stable and happy future” for her three children, who are aged between six and 18.
More than £800 of the £5,000 target has been raised so far.
Louise Harvey, 36, of Norwich, died on July 5 after she had the operation, Evening Standard says.
