Tired all the time

Persistent fatigue can come from anemia, thyroid disease, sleep apnea, depression, low B12 or vitamin D, uncontrolled diabetes, medication side effects, or chronic infections. Clindle screens fatigue with a structured visit and a broad lab panel — CBC, CMP, TSH, vitamin D, B12, ferritin, A1c — and treats the underlying cause: iron for low ferritin, levothyroxine for hypothyroidism, sleep study referrals for suspected apnea, SSRIs and counseling for depression-driven fatigue. Most patients have a clear diagnosis and a plan within one week.
