Which symptom indicates the presence of sialadenosis in Bulimia?

Sialadenosis is characterized by the swelling of the salivary glands, which is a notable symptom associated with bulimia nervosa. This condition often arises due to repeated cycles of vomiting and electrolyte imbalances, leading to enlargement of the salivary glands, particularly the parotid glands. The visible swelling can provide a clear indication of salivary gland dysfunction and is a physical manifestation commonly observed in individuals with bulimia.

While symptoms such as dry mouth, tooth sensitivity, and difficulty swallowing may also be present in individuals with bulimia, they are not specific indicators of sialadenosis. Dry mouth, for instance, may be a result of dehydration or medication side effects, tooth sensitivity can be linked to dental erosion due to acid exposure, and difficulty swallowing can arise from various conditions unrelated to sialadenosis. Therefore, the swelling of salivary glands is the most direct symptom that points to the presence of sialadenosis in bulimia, making it the correct choice.
