It has been an emotional time for Kim Kardashian, as seen in the season 17 premiere of Keeping Up with the Kardashians.
The makeup mogul and TV personality received some distressing medical news following a host of symptoms including fatigue, nausea and swollen hands.
"I feel like I literally am falling apart. My hands are numb," the 38-year-old said on camera.

The mum-of-four speculated she may have rheumatoid arthritis based on her symptoms, but decided to consult a professional.
"I have to go to the doctor and see what's going on... I can't live like this," Kardashian announced.
Dr Daniel Wallace delivered the devastating diagnosis, revealing her antibodies had tested positive for lupus and rheumatoid arthritis. An emotional Kardashian began "freaking out".
"Sometimes you can get false positives in these screenings," Dr Wallace attempted to console her.
Lupus is a systemic autoimmune disease, characterised by the body's immune system attacking the tissues and organs. This causes inflammation which can affect different systems in the body, according to Mayo Clinic.
Rheumatoid arthritis is another autoimmune disorder, affecting the lining of an individual's joints. It is mainly characterised by painful swelling.
The diagnosis preceded the May birth of Kardashian's fourth child via surrogacy, Psalm, with husband Kanye West.
The makeup mogul has been candid about her previous health struggles, including her battle with the autoimmune condition psoriasis.
Kardashian tearfully told her family that she will definitively "know on Friday" following the doctor's request for further testing.
The 38-year-old took to Twitter on Sunday to confirm she has since received the final diagnosis, describing the health scare as "a rollercoaster of emotions".
"Thinking about the pain in my hands and what it could be is really scary and can get you in a scary headspace," she wrote to her 61.8 million Twitter followers.
"I was so anxious to just figure out what was wrong."
