What physical manifestation could indicate bulimia or sialolithiasis?

Enlarged, tender salivary glands can be a significant physical manifestation of both bulimia and sialolithiasis. In bulimia, frequent vomiting can lead to irritation and inflammation of the salivary glands, particularly the parotid glands, resulting in noticeable swelling and tenderness. The repeated exposure to stomach acids during vomiting can disrupt the normal function of these glands and lead to hypertrophy.

In the case of sialolithiasis, which involves the formation of stones in the salivary glands, similar symptoms may occur due to the blockage of saliva flow caused by the stones. This blockage can cause pain and swelling in the affected gland, leading to an increase in size and tenderness.

Other options present symptoms that may be loosely associated with various conditions but do not specifically indicate the physical changes related to bulimia or sialolithiasis as clearly as enlarged, tender salivary glands do. For example, dry mouth and bad breath can occur for many reasons but are not definitive indicators of either condition. Similarly, a swollen tongue and lips, as well as excessive drooling, can occur due to a variety of reasons unrelated to these particular disorders. Hence, the most accurate and specific indicator linked to both conditions is the enlargement and tenderness of
