What are some physical consequences faced by individuals who frequently vomit due to Bulimia Nervosa?

Individuals who frequently vomit due to Bulimia Nervosa face significant physical consequences, particularly damage to the esophagus, teeth, and stomach. Vomiting introduces stomach acid into the mouth and throat, which can erode dental enamel and cause dental decay and sensitivity. This acid can also irritate and damage the esophagus, potentially leading to conditions such as esophagitis or esophageal tears. Furthermore, repeated vomiting can result in electrolyte imbalances that affect the stomach lining, contributing to additional stomach issues, including ulcers or delayed gastric emptying.

The other options do not accurately represent the primary physical consequences of Bulimia Nervosa. For instance, while weight gain can occur in some cases due to compensatory eating, it is not a direct consequence of frequent vomiting. Hair loss can sometimes happen, but it is generally associated with malnutrition rather than vomiting alone. Joint pain and muscle weakness could occur due to nutritional deficiencies, but they're not among the immediate consequences of vomiting. Improved digestion would not be applicable, as the act of vomiting typically disrupts proper digestive processes.
