The singer is currently undergoing cardiac testing.
Katie Waissel, who appeared on the singing competition X Factor in 2010, has given fans an update on her health, after revealing that she suffered a suspected heart attack earlier this year.
Taking to Instagram, the singer shared a photo of herself wearing a Holter Monitor at home.
She wrote: “Currently wearing the Holter Monitor as part of my own ongoing cardiac testing. I will be wearing this device for 48 hours as it records my heart activity.
“Other testing follows this week, but emotionally I am taking them just one test at a time.”
She continued: “Please do know that albeit this is a personal medical issue, I have listened and onboarded so compassionately to your questions and concerns relating to potential causes etc.
“I want you to know that I absolutely intend to share my findings with you and hope to either give you clarity or peace of mind to those that are seeking it.
“Until then, we must try to onboard an objective mindset and focus on staying healthy, safe and warm.”
The singer added: “I appreciate you all so greatly, and thank you for kindly embracing this discovery process with me.”
The update comes just a few weeks after Katie shared that she had suffered a “suspected heart attack”.
In her previous Instagram post, she outlined what had happened.
She wrote: “Let me tell you, I was taken by ambulance yesterday for a suspected heart attack and @nhs @ldn_ambulance Watford general AND the ambulance services were/are amazing.
