Pregnancy can be very hard on your body but Kelli Pierce was diagnosed with a rare illness triggered by her pregnancy. Kelli is the producer for Inside Sources with Boyd Matheson, and former reporter for KSL. She now has an 8 month old baby boy. Host Lindsay Aerts talks with Kelli about she felt faint during her entire pregnancy, and what she did when symptoms didn't go away after she gave birth. Kelli has since been diagnosed with POTS, Postural tachycardia syndrome, a condition where your heart rate increases when lying, then sitting up or standing. It causes dizziness or fainting.
