Tip #7: Dehydration and Risk of Acute Kidney Impairment
Maintaining fluid balance becomes increasingly important as we age, and gastrointestinal side effects can quietly put your kidney health at risk. When nausea, vomiting, or diarrhea persist over several days, your body loses critical fluids and electrolytes. This severe dehydration can reduce blood flow to your kidneys, potentially causing acute kidney injury or worsening pre-existing renal conditions.
Older adults taking concurrent medications—such as ACE inhibitors, ARBs, or diuretics for high blood pressure—face an elevated risk of kidney strain when dehydrated. Protecting your renal function requires steady hydration and consistent laboratory monitoring.
Make a conscious effort to sip fluids throughout the day, aiming for water, clear broths, or electrolyte-rich beverages. Your doctor should order routine blood work, including eGFR and serum creatinine tests, every 6 to 12 months to monitor your kidney function closely. If you experience persistent vomiting or cannot keep fluids down, contact your medical team promptly to prevent fluid imbalances.
