This article explores the risk factors and possible causes of fibromyalgia, highlighting genetic, hormonal, and lifestyle influences. It emphasizes the importance of understanding symptom triggers and underlying mechanisms for better management of the disorder.

Understanding the Key Causes and Risk Factors of Fibromyalgia

Fibromyalgia is a disorder characterized by widespread pain affecting muscles and soft tissues, often resembling arthritis in symptoms. Studies reveal women are twice as susceptible than men, possibly due to differences in serotonin production, which is about 50% faster in men, offering some protection.

The precise cause remains uncertain. The "central sensitization" theory proposes that affected individuals experience increased pain sensitivity because of hyperactive pain pathways in the brain or spinal cord.

Often coinciding with conditions like neuropathic pain and depression, fibromyalgia may be influenced by genetic factors impacting neurotransmitter pathways. Stressful events or illnesses can trigger immune and mood-related changes, heightening pain perception through hyperreactive nerves and reduced brain inhibition.

Biochemical differences affect mood, sleep, and energy, leading to common symptoms like fatigue and sleep disturbances. Genetic variations in serotonin, dopamine, and catecholamine pathways are linked to fibromyalgia, as well as other conditions such as chronic fatigue syndrome.

People with genetic traits like the 5-HT2A receptor 102T/C polymorphism are at increased risk. Lifestyle factors—including stress, smoking, obesity, and inactivity—also contribute. Trauma history, hormonal shifts during menopause, and low growth hormone levels may influence symptom severity.
