Dry eye and mouth due to fibromyalgia.

Fibromyalgia is usually characterized by generalized pain, fatigue, headache, irritable bowel syndrome, inability to sleep pleasantly, a tired and rigid awakening, and the development of cognitive disorders, including lack of concentration and mood, vertigo, etc.

Fibromyalgia syndrome is a chronic, long-term, incurable condition. About 10 million people are currently diagnosed with this disorder. Although 9 out of 10 people diagnosed are women, men are also affected by this disorder.

Association of fibromyalgia with other conditions
Studies have shown that fibromyalgia is also associated with several other conditions. In general, some patients with fibromyalgia also have dryness of the cornea, eyes and mouth.

The presence of eye discomfort or dryness and aridity is one of the most common complaints of fibromyalgia compared to dry mouth or mouth. Studies have shown that there may be a change in tear formation compared to the general population.

Sjogren’s syndrome
A syndrome called Sjogren’s syndrome is usually characterized by dry eyes and an inability to form tears. It has been observed, however, that patients with dry eyes and mouth fibromyalgia do not meet the criteria for diagnosing Sjogren’s syndrome. They are usually diagnosed with a syndrome of the mouth and dry eyes (DEMS).

Corneal sensitivity and changes in the cornea
A study of corneal sensitivity and corneal changes in fibromyalgia patients shows that the sensitivity is the same regardless of the age of fibromyalgia patients. This may be due to the deterioration of the nerves and sensory systems of the eye.

Association between fibromyalgia, chronic fatigue and Sjögren’s syndrome
The study also found an association between fibromyalgia, chronic fatigue and Sjogren’s syndrome.

Lachrymal secretion is markedly reduced in fibromyalgia, but not in the extent of other dry eye conditions. In addition, the eye becomes more sensitive to high levels of carbon dioxide, heat and cold than normal people.

Normal formation of tears
Normal tear formation is controlled by the functional unit of the tear which includes the cornea, conjunctiva, accessory lacrimal glands and Meibomian glands. All this is connected to a good network of nerves.

If part of this nervous network is impaired, the production of tears can be hindered. This is something that occurs in patients with fibromyalgia.

Dry mouth
Fibromyalgia is closely associated with irritable bowel syndrome and reduces salivary secretions leading to dry mouth. The dry mouth itself is rarely present. It is most often associated with dry eye in patients with fibromyalgia..
