The Medical Debate Is Over: Study Reveals Why the Body Hurts for No Reason

Fibromyalgia is a well-known and debilitating syndrome that causes widespread body pain, fatigue, and other symptoms, but for many years doctors and researchers have debated the true source of the problem. Now, a massive and unprecedented genetic study conducted at the University of Michigan sheds new and clear light on this mystery.

As part of the study, scientists analyzed the genetic data of more than two and a half million people and discovered 26 genetic changes associated with the risk of developing the disease. The main and clearest finding is that it is a problem with the functioning of the central nervous system and the brain—not an autoimmune disease in which the body attacks itself, as many previously thought.

The study also debunked a common myth that fibromyalgia is a disease that affects almost exclusively women. The researchers discovered that the genetic architecture of the disease is almost identical in men and women, and that the large gaps reported in the past were due to old and inaccurate diagnostic methods. It was also found that there is a strong genetic link between fibromyalgia and other medical conditions such as chronic back pain, irritable bowel syndrome, and anxiety, which explains why many people suffer from several similar symptoms simultaneously.

The new understanding that fibromyalgia originates in the brain and nervous system allows scientists and doctors to move toward more precise solutions. Instead of looking for drugs for the immune system, efforts will focus on advanced treatments that directly affect areas of the brain responsible for pain processing, with the hope that in the future it will be possible to detect and treat the problem at much earlier stages.
