After three weeks of “Rest, rest and more rest,” Wendy Williams returned to “The Wendy Williams Show” Monday morning following a doctor-mandated break from TV. On Feb. 21, Williams announced that her doctor ordered her to take a three-week break from her show because of symptoms related to her hyperthyroidism, publicly revealing her Graves’ disease diagnosis.

Williams addressed her absence and return at the top of the show before diving into her usual celebrity-centered “Hot Topics” segment.

In February, Williams said her symptoms included sleeplessness, irritability, rapid heartbeat, trouble swallowing and heat intolerance.

Williams, 53, who lives in Livingston and grew up in Ocean Township, wiped tears from her eyes with cotton swabs in the middle of the segment, thanking staff and crew at her show for their support.

In October, Williams fainted on live TV during a Halloween episode of her show, staggering and falling down in her Statue of Liberty costume.

Later on Monday’s show, Dr. Mehmet Oz, Williams’ network mate on Fox and fellow New Jerseyan, visited the show to talk about the health conditions Williams is facing.

Williams, who said she was diagnosed with both hyperthyroidism and Graves’ disease 19 years ago, tearfully recounted how her husband called Dr. Oz to assist the talk show host after her most recent bout of symptoms.

“You saved your life, I’ll make it real simple,” Oz, who lives in Cliffside Park, told Williams.

“It’s been a long three weeks, but necessary,” Williams told “Good Day New York” in an interview that aired Monday morning.
