There's a strong connection between weight gain and sleep apnea. Often its misunderstood as "Oh just go on a diet and your sleep apnea will go away!" That works in some cases but for many it doesn't. Turns out the SA caused the weight gain via unknown mechanisms. Perhaps inflammation, perhaps sugar/food cravings to make up for lost energy, fatigue, etc.
