Lizzie, who was hospital from Sunday until Thursday explained that after having a swab taken, it was found she had "two [types of] bacteria that are superbugs and [not] normally found together."
"They are known to cause sepsis [and] are called pseudomonas and klebsiella," the reality star continued.
"They're treated by IV antibiotics and are resistant to oral antibiotics. My obstetrician had contacted the infectious disease unit which had told her I needed hospitalisation."
