was ist stoffwechsel — which blood markers matter?

Metabolism refers to all biochemical processes that convert food into energy and build or break down body tissues. Key blood markers for assessing metabolic health include: fasting glucose and HbA1c (glucose metabolism), triglycerides, total/LDL/HDL cholesterol (lipid metabolism), and liver enzymes (ALT, AST, GGT) as indicators of metabolic liver stress. Thyroid markers (TSH, fT4) and kidney function (creatinine, eGFR) are also important because they influence basal metabolic rate and waste elimination. If insulin resistance is suspected, fasting insulin or HOMA‑IR can be measured. Direct‑to‑consumer tests often include a subset of these markers, but lack clinical interpretation. A single value is rarely meaningful – only in combination with history, lifestyle, and serial measurements does a reliable picture emerge. Be cautious: minor deviations are common and not necessarily pathological. Evidence: These markers are well‑established in routine clinical practice (human‑strong).
