Secretly Suffering! The Hidden Reason For Kris Jenner's Weight Gain Revealed

Keeping up with the Kardashians matriarch Kris Jenner has gained a tremendous amount of weight in recent months. But after recently hiring a trainer and changing her eating habits, RadarOnline.com has exclusively learned that the weight gain is partly due to a medical issue that she cannot change — menopause!

"Kris is currently doing estrogen replacement therapy to try and combat the signs of menopause," a Kardashian family insider told RadarOnline.com.

"She has been incredibly emotional lately and has had a really hard time keeping it all together."

"She's been very snappy lately, but everyone in the family is starting to feel compassion for her right now because of what she is going through," said the source.

As RadarOnline.com previously reported, Jenner's weight gain became evident during a recent trip to St. Barth's with her much younger boytoy, Corey Gamble, 35. The shocking photos of her bulging bikini body prompted her to get her fitness back on track, said the source.

"Not only is this affecting Kris right now, but it is also affecting her relationship with Corey," the source told RadarOnline.com.

"He loves her very much, but he is also at a place in his life where he kind of wants kids of his own, and now it looks like she won't be able to give them to him."
