was heißt hb — what can you do yourself?

Hb stands for hemoglobin, a protein in red blood cells that carries oxygen. Normal ranges are roughly 13.5–17.5 g/dL for men and 12.0–16.0 g/dL for women. Low Hb (anemia) may indicate iron, vitamin B12, or folate deficiency – dietary sources like red meat, legumes, spinach, and possibly supplements (under medical guidance) can help. High Hb can result from dehydration, smoking, or living at high altitude; staying hydrated and quitting smoking are beneficial. Self-management is limited: without a proper diagnosis, avoid high-dose supplements. Consumer biomarker tests like MyBody-X provide data but not a clinical diagnosis. Consult a doctor for abnormal results.
