The blockage resulted in a stroke that left her in critical condition.
"It is with heavy hearts that we confirm the passing today of Katie May-mother, daughter, sister, friend, businesswoman, model and social media star-after suffering a catastrophic stroke caused by a blocked carotid artery on Monday.
"Katie was a star in every sense of the word and I'll never stop missing her," May's brother, Stephen, said in a statement.
May is survived by her seven-year-old daughter and the family has started a GoFundMe page to try and raise USD 100,000 to support the child.
"Anyone who was lucky enough to know Katie May was truly blessed by her incredible heart, mind and soul. She was an inspiration and a guiding light to so many people in this world," the donation page reads.
