Why Monitoring Matters in Geriatrics

In geriatric care, medications that work well for younger patients may pose risks to older adults. Age-related changes in liver and kidney function can lead to toxic accumulation of drugs, even at standard doses. According to the American Geriatrics Society, adverse drug events account for nearly 100,000 hospitalizations annually among older adults in the U.S.

Common risks minimized through lab monitoring

  • Electrolyte imbalances caused by diuretics
  • Blood thinning complications from anticoagulants
  • Liver stress from cholesterol-lowering drugs
  • Kidney impairment from NSAIDs or certain antibiotics
  • Drug-to-drug interactions in polypharmacy cases

Recognizing Red Flags Before They Escalate

Many adverse effects of medications begin subtly and worsen over time. Through regular lab testing, Dr. Cook can catch early warning signs — even before symptoms become visible.

Subtle signs detected through lab monitoring

  • Unexplained fatigue or dizziness
  • Swelling in the legs or hands
  • Fluctuating blood pressure
  • Changes in appetite, sleep, or mood
  • Abnormal lab values with no outward symptoms

By interpreting these lab markers in context, Dr. Cook adjusts treatment before side effects compromise health.
