Can Insulin help with Müdigkeit?

Insulin is a hormone that regulates blood sugar, not a treatment for fatigue. In non-diabetic individuals, exogenous insulin can cause hypoglycemia (low blood sugar), which itself leads to fatigue, shakiness, dizziness, or loss of consciousness – the opposite of the desired effect. In diabetic patients, optimized insulin therapy may indirectly improve energy by stabilizing glucose fluctuations, but this is not a general recommendation and requires medical supervision. There is no scientific evidence that insulin alleviates fatigue in healthy people. On the contrary, self-administering insulin is dangerous. Persistent fatigue should be evaluated for common causes (sleep deprivation, iron deficiency, thyroid dysfunction, stress) by a healthcare professional. The provided context contains no data on insulin as a fatigue therapy. Evidence: practice (medical standard).
