An 85-year-old woman has settled her lawsuit against a slimming centre in which she sought a full refund and damages over a $400,000 weight-loss package.

Madam Gan Siew Hong , who has diabetes and other health problems, visited the Ngee Ann City branch of London Weight Management in July 2013 with her husband and her son after seeing its TV commercial touting a weight-loss trial session for $18. The family, who live in an HDB flat, eventually paid about $400,000 for weight-loss treatments and products.

In a lawsuit filed in the High Court on Aug 3 this year seeking compensation of close to $450,000, Madam Gan alleged that the treatments not only failed to improve her health, but also caused her to suffer diarrhoea, a skin rash and pus discharge. She claimed that the centre pressured her family into signing up for a six-year package.

In its defence filed on Aug 31, London denied this but said it was willing to refund the unused portion of the package amounting to $43,408 out of goodwill. The centre said Madam Gan's family declared only that she had diabetes and that it is not liable for injuries resulting from non-disclosure of medical history.

The centre also said it had advised her to seek medical advice on the suitability of its treatments and products.

In a joint statement to The Straits Times yesterday, Madam Gan and London Weight Management said: "We... have amicably resolved all claims and any claims and/or demands between the parties."

Both parties "further unconditionally withdraw all allegations against each other", said the statement, sent by Madam Gan's lawyers from Lim & Bangras. Financial details of the settlement are not known.
