Salivary gland disorders affect the glands that produce saliva, which is essential for digestion and oral health. Common conditions include sialolithiasis, where stones form in the glands, and sialadenitis, an inflammation often caused by infection. Symptoms may include dry mouth, swelling, and pain in the affected area. These disorders can result from various factors, including dehydration, autoimmune diseases like Sjogren's syndrome, and certain medications. Diagnosis typically involves physical examination, imaging tests, or biopsies. Treatment options vary based on the specific disorder and may include hydration, antibiotics, or surgical intervention to remove blockages or damaged tissue.
