Singer Solange Knowles has revealed she was diagnosed with a nervous system disorder. The singer-songwriter canceled a New Year's Eve concert so she could tend to her health.
On Dec. 27, Solange took to her Instagram account to announce she would have to bow out from a scheduled performance at the Afropunk Johannesburg concert in South Africa on Dec. 31. She disclosed that she was dealing with a freshly diagnosed health issue.
"The past five months I have been quietly treating, and working through an Autonomic Disorder," Solange wrote. "It has been a journey that hasn't been easy on me... Sometimes I feel cool, and other times not so cool at all."
The singer-songwriter did not specify her specific disorder, noting that the diagnosis was complicated and that she wanted to maintain a measure of privacy about her health.
Autonomic disorder is an umbrella term for several disorders that could disrupt the body's autonomic nervous system. Around 1 million Americans have an autonomic disorder, reports the New York Daily News.
The New York University Langone Dysautonomia Center notes these disorders could result in problems with digestion, standing without fainting and other organ functions. Symptoms can include abdominal pain, nausea and vomiting, reports New York Daily News.
"It's a complicated diagnosis, and I'm still learning so much myself, but right now, my doctors are not clearing me for such an extended lengthy flight, and doing a rigorous show right after," Solange continued.
The musician pledged to return to Johannesburg to perform at the Afropunk concert in the future and said she would spend upcoming months focusing on her physical well-being.
"As a part of the self care that I've tried to encourage this past year, it needs to start with myself, and I'm looking forward to doing a better job of this 2018," Solange wrote.
Several prominent celebrities have disclosed serious health diagnoses in recent months. Actress and singer Selena Gomez revealed she had a kidney transplant after having had lupus for several years. Model Chrissy Teigen revealed she was working through postpartum depression and actress Julia Louis-Dreyfus publicly announced she was being treated for breast cancer, according to Vogue.
Solange is the younger sister of Beyonce Knowles and a distinguished performer in her own right. On Feb. 12, she won the Grammy award for Best R&B Performance for her song "Cranes in the Sky," Essence reports.
Solange has not disclosed what types of medical treatment she is getting for her disorder.
