Aquino shared the image less than an hour after she revealed her health problems via a Facebook Live video.

She said she was diagnosed with signs of lupus, that she suffers from fibromyalgia, and opened up about her thyroid condition, her allergies, and her issues with hypertension.

Aquino also revealed that she's flying to Singapore on Sunday to undergo a positron emission tomography (PET) scan after failing to gain back any of the weight she lost.

Captioning her photo, she wrote that she'll definitely update her fans if the results of the test are "encouraging."

She added, however, that she'll be "obeying" her doctors, who have told her to stay away from social media to avoid stress.

Aquino took to social media after a Nicko Falcis interview, wherein her former business partner alleged that she sent him death threats over their legal battle, was published.

She has accused Falcis of stealing from her more than a million pesos.
