16 Symptoms of Sleep Apnea

6. Weight Gain

Poor quality sleep can also result in weight gain. When we don't get enough high-quality sleep, our bodies produce an excess of a hormone called ghrelin, which tells our bodies that we need to eat.

A lack of sleep also causes the body to produce less of a hormone called leptin, which signals our bodies to stop eating. Sleep may also affect insulin levels. Sleep deprivation makes our bodies insulin-resistant, which causes additional insulin production.

The body will crave unhealthy food as a result of these fluctuations.
