Though she is no stranger to yo-yo-dieting, Ricki Lake's recent weight gain has left many worried about the actress' health.

“She looks as if she’s gained 80 pounds,” Dr. Stuart Fischer, who has not treated the 46-year-old Hairspray star, told Radar Online.

“If she keeps this up, she’ll put herself at risk for 65 life-threatening diseases," Fischer added.

Ricki's latest weight fluctuation is reportedly due to her recent divorce from her second husband, jewelry designer Christian Evans. The former couple — who tied the knot in 2012 — announced their separation after two years of marriage last October.

The proud mom — she has two sons, Milo, 18, and Owen, 13 — was previously hitched to illustrator-bartender Rob Sussman from 1994 until 2005.

“Every time her weight goes up, she increases her blood sugar and cholesterol to dangerous levels,” Fischer said of Ricki's newest weight gain.

“Every time she uses a starvation diet, she risks cardiac arrest and stroke. She’s not a kid anymore. Her body just can’t take it," the doctor added.
