## Step 1<br />Bulimia nervosa is an eating disorder characterized by episodes of binge eating followed by compensatory behaviors such as purging, fasting, or excessive exercise. This disorder can have severe health consequences if left untreated.<br /><br />## Step 2<br />Option A, "Increased muscle mass," is not a likely outcome of bulimia nervosa. In fact, individuals with bulimia nervosa often engage in purging behaviors that can lead to muscle loss.<br /><br />## Step 3<br />Option B, "Increased physical fitness," is also not a likely outcome. The disorder often leads to physical and mental health deterioration, not improvement.<br /><br />## Step 4<br />Option C, "Obesity," is not a typical outcome of bulimia nervosa. The disorder is characterized by cycles of binge eating and purging, which can lead to weight fluctuations but not necessarily obesity.<br /><br />## Step 5<br />Option D, "Tooth decay," is a likely outcome of bulimia nervosa. The purging behaviors, particularly vomiting, can lead to tooth decay due to the exposure of teeth to stomach acid.
