In a study, gout was almost twice as common in the sleep apnea group as in the comparison group, reports Reuters.

“When people have a gout attack it’s so painful, they have limited mobility, they cannot put even one piece of paper on the toe,” Zhang told Reuters Health.

Although obesity increases the risk for sleep apnea, some thin people have sleep apnea, too, and even in these people the risk of gout was increased by 80 percent, he said.
