was ist fettstoffwechsel — what symptoms are typical?

The provided context does not directly address symptoms of lipid metabolism disorders. In general medical knowledge, lipid metabolism disorders (e.g., hypercholesterolemia, hypertriglyceridemia) often remain asymptomatic for years. Typical physical signs include xanthelasmas (yellowish cholesterol deposits on eyelids), arcus corneae (white ring around the cornea), and tendon xanthomas (e.g., on the Achilles tendon). Very high triglycerides can trigger acute pancreatitis. Long-term, disturbed lipid metabolism increases the risk of atherosclerosis, heart attack, and stroke. Diagnosis is made via a fasting lipid profile. Genetic forms like familial hypercholesterolemia often show elevated LDL levels in childhood. The context lacks specific studies or guidelines on symptoms; the above information is based on established medical knowledge. If a lipid disorder is suspected, a physician should be consulted.
