Living with fibromyalgia pain can contribute to depression and anxiety. But some experts believe there are other related conditions that could be contributing to your blues.
Chronic, widespread muscular pain and tenderness, sleep problems and fatigue, morning stiffness and headaches, concentration and digestive irregularities: All of these symptoms can make daily functioning very difficult for those withfibromyalgia. But equally challenging are the depression and anxiety that often accompany the disorder.
Over a lifetime, as many as 62 percent of fibromyalgia patients may experience symptoms of major depressive disorder, and 56 percent may experience some type of anxiety disorder. According to Jacob Teitelbaum, M.D., medical director of The Fibromyalgia & Fatigue Centers, anxiety in people with fibromyalgia often manifests itself as rapid shallow breathing (hyperventilation), while depression may be expressed as a decrease in normal interests.
While it is not unexpected to have an emotional or psychological response to a chronic illness, there may be other physiological reasons that explain why anxiety and depression occur in fibromyalgia patients consistently enough that they are listed as symptoms of the condition. “Biochemically, depression is very different in [people with] fibromyalgia than otherwise,” says Dr. Teitelbaum. “In fibromyalgia, it is often associated with an underactive adrenal function [a low cortisol level], whereas depression [in a non-fibromyalgia population] is associated with a high cortisol level.”
Fibromyalgia: Physical Factors That Can Affect Emotional Health
According to some doctors who routinely treat fibromyalgia, there are a number of factors that appear to increase the likelihood of developing anxiety and/or depression if you have this condition.
Low cortisol levels. Cortisol is a hormone produced by the adrenal glands in response to stress. When the adrenals produce an insufficient supply of cortisol, however, it can result in what’s sometimes called “adrenal fatigue;” symptoms include muscle aches and pains, extreme fatigue, anxiety, and elevated levels of cholesterol, blood sugar, and blood pressure. According to Dr. Smith, adrenal fatigue can occur when the body is under stress for extended periods of time. “When you are first stressed, cortisol elevates,” she explains. “But if you stay stressed for a long time, the body can’t keep up by making extra cortisol, so it makes just enough to keep you alive.”
Dr. Smith says that low cortisol levels related to stress often do not show up on standard blood tests, and she believes they are best measured by saliva testing. “Many physicians only measure cortisol levels as related to Addison’s disease or Cushing’s disease. They do not look at what happens when the body makes only enough cortisol to stay alive but not to function well (adrenal fatigue),” she explains.
Cortisol levels can be normalized by reducing stress, says Dr. Smith. Techniques Dr. Smith recommends include “prayer, meditation, tai chi, yoga, breathing techniques and massage, [although] herbal therapies, adrenal extracts, and medications may all be necessary to bring cortisol levels back to normal.” she says, adding, “it may take one to two years to fully normalize the body’s stress system.” As cortisol levels are restored, fibromyalgia-related anxiety and depression generally lessen, she notes.
Poor mitochondrial functioning. Mitochondria are the energy-producing parts of the cell that assist in vital body processes like metabolism. When their function is impaired, they can also play a role in the development of depression and anxiety in people with fibromyalgia, says Dr. Smith. She reports that in her patients, supplements such as coenzyme Q10 (CoQ10), the amino acid-like compound L-carnitine, NADH (nicotinamide adenine dinucleotide, which is related to niacin, a B vitamin), D-ribose, and the antioxidant alpha-lipoic acid all help to refuel mitochondria. And in some patients, taking these supplements has been helpful in reducing symptoms of depression and anxiety related to fibromyalgia.
Vitamin D deficiency. Fibromyalgia has been linked to low levels of vitamin D, which has also been found to occur more frequently in patients with anxiety and depression. Vitamin D deficiency can be offset by supplementation and eating foods enriched with this nutrient, such as fortified orange juice or margarine.
Poor sleep. Insufficient restorative sleep can lead to or aggravate existing anxiety and depression in people with fibromyalgia, and they do not go into the stage of sleep known as REM sleep, says Dr. Smith. This problem may be further compounded by taking antidepressant medication, which can suppress REM sleep in certain people. Other causes of non-restorative sleep in patients with fibromyalgia can include muscular aches and pains and, according to one study, decreased levels of the hormone melatonin.
“There really are metabolic reasons why people with fibromyalgia have the symptoms that they have,” says Dr. Smith. She recommends that people with fibromyalgia undergo testing to determine if an underlying deficiency or a related health condition could be complicating their situation and bringing depression and anxiety to the surface.
