was sind hb werte — what can you do yourself?

The question about Hb (hemoglobin) values and what one can do personally is not directly addressed in the provided context. Hemoglobin is a protein in red blood cells that carries oxygen. Normal Hb levels are roughly 13.5–17.5 g/dL for men and 12.0–15.5 g/dL for women. Low values (anemia) can result from iron, vitamin B12, or folate deficiency. Self-measures include an iron-rich diet (e.g., red meat, legumes, spinach) combined with vitamin C (e.g., lemon juice) to enhance absorption. For chronically elevated values (polycythemia), adequate hydration and smoking cessation are recommended. However, self-management does not replace medical evaluation. The context lacks specific Hb data; the evidence is based on general medical knowledge, not the provided sources.
