Usually bilateral?
Yes, but distribution alone proves nothing.

What can enlargement of both salivary glands mean?
Sialadenosis is a persistent enlargement of salivary glands that is neither inflammatory nor caused by a tumour, most often affecting the parotid glands. It is commonly bilateral and minimally painful. Diagnosis requires assessment for other causes of swelling.

The gland enlarges diffusely
Swelling commonly lies in front of and below the ears. Diffuse enlargement differs from a focal lump; appearance alone cannot establish the cause.
Investigate associations
Metabolic or nutritional disorders and medicines can be involved. History and examination, often supplemented by ultrasound, help distinguish the causes.
Address the underlying condition
If an underlying disorder is identified, management also addresses it. Further steps depend on progress; surgery or antibiotics are not automatic requirements.

Often confused
Gland size and saliva quantity differ
Sialadenosis describes gland enlargement. This does not reliably establish excessive or reduced saliva production.
Quick answers
Is sialadenosis inflammation?
No. Sialadenitis is a different condition. Both can cause swelling and must be distinguished.
Does it prove an eating disorder or alcohol problem?
No. There are various possible associations; a facial appearance cannot establish the cause.
When should swelling be assessed?
New or persistent gland swelling needs assessment, particularly a one-sided lump, pain or rapid change.

You can bring this question to your appointment:
Which causes have been excluded, and should an underlying condition be investigated?
An examination can clarify the finding and any need for referral.
