What are the 7 symptoms of chronic fatigue syndrome?

While there isn't a strict "7 symptoms" list, core symptoms of Chronic Fatigue Syndrome (CFS/ME) often highlighted include severe fatigue not relieved by rest, Post-Exertional Malaise (PEM - worsening symptoms after activity), unrefreshing sleep, cognitive issues (brain fog), muscle/joint pain, headaches, and tender lymph nodes or sore throat, with other common signs like dizziness or lightheadedness. A diagnosis requires profound fatigue plus at least four of these key issues, though symptoms vary.

Evaluation of ME/CFS
  • Complete blood count with differential.
  • Erythrocyte sedimentation rate (ESR)
  • Electrolytes.
  • Fasting glucose.
  • Renal function: creatinine. blood urea nitrogen (BUN) glomerular filtration rate.
  • Calcium.
  • Phosphate.
  • Liver function: bilirubin. alanine aminotransferase (ALT) alkaline phosphatase (ALP)


Can anemia cause shortness of breath?

Yes, anemia frequently causes shortness of breath because your blood lacks enough healthy red blood cells to carry sufficient oxygen to your body's tissues, making your heart and lungs work harder, especially during activity.

What tests are done for shortness of breath?

Tests for shortness of breath (dyspnea) check heart and lung function, ranging from simple blood tests (like BNP for heart failure) and imaging (X-ray, CT scan) to detailed Pulmonary Function Tests (PFTs) like spirometry, lung volume tests, diffusion tests, and exercise challenges (e.g., 6-minute walk test, CPET) to see how your body handles activity, helping diagnose causes like asthma, COPD, heart failure, or pneumonia.

What vitamin deficiency causes shortness of breath?

Shortness of breath (dyspnea) can signal vitamin deficiency, primarily due to B12 (cobalamin) or folate (B9) deficiency causing anemia, where large, ineffective red blood cells struggle to carry oxygen, leading to breathlessness, fatigue, and weakness. Iron deficiency anemia also causes shortness of breath. Less commonly, severe Vitamin C deficiency (scurvy) has presented with severe breathing issues, including pulmonary hypertension.
