"Late last week I wasn’t feeling well and was feeling a little short of breath. I know my body and I know when I should be concerned so I went to the hospital to get checked out," she wrote. "After some routine tests I was diagnosed with blood clots in my lung."
Leakes said that constant plane travel contributed to her blood clots.
"I’m thankful to be alive as the doctor advised me that most people don’t recognize the symptoms of blood clots and don’t go to the doctor and that’s when the big problems start happening," she added. "I am fortunate to have had a wonderful experience with the doctors and nurses who took care of me."
Real Housewives alum Kim Zolciak sent Leakes her well wishes in a statement to E! News.
"My thoughts and prayers are with NeNe at this time. I know she will be back to her feisty self in no time," she said.
