Possible Causes
Generally, Low saliva production can be related to:
- Sjogren Syndrome
An autoimmune disease where the immune system attacks the organs that produce tears and saliva, resulting in dry eyes and dry mouth. In some cases, internal organs can also be gradually affected. Disease severity is highly variable.
- Fabry Disease / Lysosomal Storage Disorder
Fabry Disease is a rare genetic condition caused by a problem with the GLA gene, which leads to a lack of an important enzyme called alpha-galactosidase A. This causes fatty substances to build up in the body, affecting the skin, heart, kidneys, and nervous system. Symptoms can include burning pain in the hands and feet, small dark red spots on the skin, and trouble sweating. If not treated, it can lead to serious problems like kidney failure, heart disease, and strokes.
- Systemic Lupus Erythematosus (SLE)
An autoimmune disease caused by the body's immune system attacking organs and cells. The exact cause is unclear, but risk factors include being female, childbearing age, and heredity. SLE may involve nearly every organ system in the body with a wide range of potential symptoms that often wax and wane over time.
Related Serious Diseases
Sometimes, Low saliva production may be related to these serious diseases:
- Recurrent Parotitis
Recurrent infections of the parotid gland (saliva-producing organ below the ear). These result in parotid swelling and pain and occasional fevers. It can be due to dehydration, infection, inflammation, or stones in the salivary gland ducts.
- Bell's Palsy
Doctor's Diagnostic Questions
Your doctor may ask these questions to check for this symptom:
- Is your mouth drier than before?
