Famous model Gigi Hadid has thyroid disease, and thyroid becomes underactive, and the symptoms that result include fatigue, heavy periods, depression, and sometimes weight gain or difficulty losing weight.

Gigi Hadid got honest about a bunch of facets of her life earlier this week — including her health. In particular, she shed some light on what it was like to prepare for the Victoria's Secret Fashion Show while also dealing with a thyroid disease. "My metabolism actually changed like crazy this year," she explained. "I have Hashimoto's disease. It's a thyroid disease, and it's now been two years since taking the medication for it."
