If you have fibromyalgia with painful tender points, deep muscle pain, and fatigue, exercise is probably the last thing on your mind. Yet, exercise may be just what the doctor ordered. Whether it's daily walks, stretching, swimming, yoga, tai chi, or Pilates, low-impact exercise programs can keep you fit in spite of your fibromyalgia -- and may help reduce your pain, as well.
Fibromyalgia is a common condition that causes painful muscles. The pain is severe and involves many muscles as well as tendons, ligaments, and other soft tissue areas. Fibromyalgia has also been linked to fatigue, sleep problems, headaches, cognitive dysfunction, depression, and anxiety.
Irritable bowel syndrome (IBS) is a disorder that involves abdominal pain, cramping, bloating, as well as changes in bowel movements - constipation or diarrhea, or alternation of both. People with IBS often experience anxiety and depression.
Millions of people have at least one of these conditions. Fibromyalgia affects 5 million U.S. adults, and an estimated 30 million to 47 million people in the U.S. have IBS.
If you have fibromyalgia or IBS, you may be more likely to have the other one, too.
Studies have estimated that 32% to 70% of people with fibromyalgia also meet criteria for IBS.
Linked but Separate
The root causes of fibromyalgia and IBS are not clear; both are functional disorders, which means there's nothing visibly wrong with the structure of the organs, but with how they work.
But there is relationship between two, says Michael J. Pellegrino, MD, a fibromyalgia expert at Ohio Pain and Rehab Specialists in North Canton, Ohio, and an expert on WebMD's Fibromyalgia Exchange. Pellegrino, who has fibromyalgia, says he also has intermittent IBS that he considers mild.
“There’s some connection because they come in clusters, but we don’t know what it is right now,” says Albena Halpert, MD, an assistant professor of gastroenterology at Boston University's medical school.
Researchers see a possible pain link between IBS and fibromyalgia. In short, people with those conditions respond to pain differently than people without the two conditions.
IBS patients are hypersensitive to intestinal pain; people with fibromyalgia are hypersensitive to skin and muscle pain. There is a lowered threshold to pain sensation, in general, Halpert says.
It’s been also found that people with these conditions respond favorably to a certain group of antidepressants, which suggests they share a similar underlying cause.
In fibromyalgia, the central nervous system may be highly sensitive, making someone feel more pain than what someone without fibromyalgia would feel in a similar situation. And the central nervous system is not as able to block or inhibit the pain compared to someone without the condition, Pellegrino says.
In IBS, someone has the urge to pass a bowel movement that is often associated with bowel cramping, and the body fails to curb those pain signals. Similarly, a very mild trigger -- such as certain foods that don't bother most people -- can result in cramping someone with IBS, Halpert says.
Both conditions can drastically hamper daily life. For instance, someone with IBS may have to rush to bathroom after the abdominal pain begins. The symptoms can last a couple of hours to a day at a time, she says.
“We can’t figure out how to shut the pain signals off, whether it’s IBS or fibromyalgia. It’s the continuous and overwhelming signals that can’t be handled,” Pellegrino says.
There are treatments for IBS and fibromyalgia. They can include medications and/or lifestyle changes that address symptoms.
The key, Pellegrino says, is learning how to manage these conditions and how to deal with the stigma that may come with them. Talking with your doctor and finding a support group may help.
