Salivary gland infections

Symptoms and causes

Origin

Most infections of the parotid gland are viral. Bacterial infections are often related to dehydration and a compromised immune system. They are more often seen in older people who have poorly regulated diabetes.

Symptoms

Infections of the parotid glands (submandibular salivary gland) are accompanied by:

general malaise
chewing and eating can also be painful
fever
pain
redness
swelling

These infections can be caused by an underlying obstruction (e.g. by a stone). They might also be part of any one of a number of autoimmune diseases.

If the inflammation of the parotid gland is on both sides, mumps should also be ruled out. This is no longer a frequent occurrence thanks to the vaccination campaigns.

Diagnosis and treatment

Treatment

Bacterial infections usually respond well to treatment with antibiotics. Good hydration is important and lozenges are also advisable.
