The taxing effects on your gastrointestinal system when struggling with bulimia nervosa can be extremely serious and even results in additional bloating and cramping in the gut. This can cause a vicious cycle of self-image concerns, leading to even more binge-eating and purging. In order to reduce stomach issues, consuming aloe vera juice is a common recommendation. Aloe vera has anti-inflammatory properties that can calm the stomach and help promote proper digestion, so some of the nutrients in the consumed food can be used before being purged.
