Lana Del Rey has had to cancel many of her upcoming European shows and performances due to health issues.

“For medical reasons independent of our will, the artist has been forced to cancel all promotional activities planned in Europe over the coming days,” the Young and Beautiful singer’s label told MTV UK in a statement.

Lana has been experiencing health problems for a while now and last summer she opened up about her struggles saying,

“I’d been sick on tour for about two years with this medical anomaly that doctors couldn’t figure out. That’s a big part of my life: I just feel really sick a lot of the time and can’t figure out why.”

She said that she has suffered from the illness for several years and that her symptoms come and go and can range in severity. She also said that she had tried to hide her illness, but felt like her fans deserved an explanation.

Doctors have not been able to determine exactly what is wrong with Lana, and therefore cannot cure or heal her. Until her doctors are able to find a diagnosis for her problems, it’s likely that Lana will continue to suffer from them.

Last week, the singer canceled two private shows that she had planned to perform in Paris for Virgin Radio listeners.

She has also been silent on Twitter since posting her video for Ultraviolence in June.

Lana did not say how long she will be postponing her tour and appearances, and is scheduled for several performances in the US throughout October.

Hopefully Lana will be able to recover in time to make the rest of her scheduled appearances and hopefully her doctors will find a way to treat her illness and determine exactly what is causing her to feel bad.
