Chronic Fatigue Syndrome: Causes, Symptoms, and What You Can Do

When you hear chronic fatigue syndrome, a complex condition marked by extreme tiredness that doesn't improve with rest and often worsens after physical or mental activity. Also known as myalgic encephalomyelitis, it's not laziness, burnout, or a phase—it's a real, measurable illness that affects millions worldwide. People with this condition don’t just feel worn out. They experience post-exertional malaise, a severe crash in energy after even small efforts, like walking to the mailbox or talking on the phone. This isn’t normal tiredness. It’s a flare-up that can last days, weeks, or longer, and it’s one of the most disabling symptoms.

Many people with chronic fatigue syndrome also struggle with brain fog, trouble focusing, memory lapses, and difficulty finding words. Sleep doesn’t refresh them. Light, noise, or stress can make symptoms worse. It’s not just about energy—it’s about how your nervous system, immune system, and metabolism respond to everyday demands. Studies show these patients often have abnormal immune markers, disrupted sleep cycles, and altered energy production in cells. But there’s no single blood test to confirm it. Diagnosis comes from ruling out other conditions and matching symptoms to established criteria.

What causes it? No one knows for sure. Some cases start after a viral infection like Epstein-Barr or Lyme disease. Others follow severe stress, trauma, or long-term illness. It’s not contagious, but it can run in families, suggesting a genetic link. Women are diagnosed more often than men, but that might be because men are less likely to seek help. The good news? Many people find ways to manage it. Small, consistent changes—like pacing activities, improving sleep hygiene, and reducing stress—can make a real difference. Some find relief with targeted supplements, physical therapy, or cognitive strategies. Others learn to adjust their lives around their limits instead of fighting them.
