Does weight gain cause sleep apnea?
A person who gains 10 pounds experiences a six-fold increase in his chances of developing sleep apnea, notes WebMD. People with extreme obesity are also more likely to develop obesity-hypoventilation syndrome, which can occur alongside sleep apnea or arise alone. Studies show a correlation between sleep apnea and being overweight. Patients who lost weight were three times more likely to experience a complete remission of their symptoms than those who did not lose weight.
