People with fibromyalgia often experience muscle weakness. This weakness could explain why they suffer from dysphagia. The muscles that control the process of swallowing may be affected by the general weakness caused by fibromyalgia.

In addition, we know that people with fibromyalgia have problems with their nervous system. An NIH study found that patients with fibro had significantly more neurological abnormalities than a control group. If fibromyalgia is a condition that affects the nervous system, as many doctors suggest it is, then it could be causing a breakdown between the nerves that control the esophagus and the brain.

This would explain why people with fibromyalgia have a hard time swallowing. Their brain can’t control the muscles in the esophagus as it normally would. But until we know more about the condition, we can’t say for sure what the link is.

This is an incomple list of known Fibromyalgia "Aggravating Factors." That is, a person with Fibromyalgia is more prone to experience these symptoms. Not every person with Fibromyalgia will experience all of these. A person with Fibromyalgia may never experience all of these at once but could experience them all at some point in your journey with Fibromyalgia:

How many of these have you experienced or are still experiencing? I see no reason why difficulty swallowing wouldn't be added to this list of ailments that tag along with the diagnosis of Fibromyalgia.

Yes, but it is not related to the Fibromyalgia. I was diagnosed by a Gastroenterologist with Achalasia which is a rare swallowing disorder. When your esophagus works normally the motion that moves food into your stomach is called peristalsis and when it stops its in aperistalsis. With Achalasia you're in aperistalsis and the muscle that connects the esophagus to the stomach won't relax and food just sits there. I kept feeling like I was having a heart attack until they preformed one simple swallowing pressure test and I was diagnosed. The surgery to repair Achalasia is usually a simple laproscopic or robotic procedure. Unfortunately because of having other abdominal surgery that installed a large piece of mesh (20cm x 30cm) I had to have an open procedure that took 7 hours in surgery, but was well worth it. Recovery went extremely well and I spent less than a week in the hospital and was eating solid food 3 days after the procedure. I had a great thoracic surgeon. The bad part is that my insides now look like a grenade went off in there. (the surgeon's analogy). And I do still have serious gastroesophogeal reflux issues and gastroparesis (very slow motility of the stomach and intestines.

Dysphagia can occur at any age, but it's more common in older adults. The causes of swallowing problems vary, and treatment depends on the cause.

Symptoms
Signs and symptoms associated with dysphagia may include:

Drooling
