3. Weight Gain
When you don’t get a good night of sleep, usually you don’t want to hit the gym or go for a run. If anything, you want to spend the whole day in bed. Not only does sleep apnea take away the energy you need to exercise, but it also affects your hunger hormones. Sleep apnea can cause your body to release extra ghrelin, the hormone that stimulates your appetite (particularly for sweets and carbs), and it decreases your production of leptin, which is the hormone that tells you when you’re full. As a result, you will start eating more carbs and sweets, and not know when you’re actually full. The excess caloric intake combined with lack of exercise will cause weight to start creeping up.
