Age-Related Hearing Loss: Mechanisms, Cognitive Links, and Nutritional Support
Age-related hearing loss (presbycusis) affects over 60% of adults over 70 and independently accelerates cognitive decline. This article reviews the mechanisms and the limited but growing evidence base for nutritional support.

Kidney Health and Aging: GFR Decline, Protein Intake, and Renoprotective Strategies
GFR declines ~1 mL/min/year after age 40. In early-stage CKD, protein restriction, blood pressure control, and avoiding nephrotoxic supplements (high-dose oxalate, aristolochic acid) are the primary levers. Potassium citrate and omega-3 have supportive evidence.

Nocturnal Blood Pressure Non-Dipping: The Hidden Cardiovascular Risk You Can Measure
Blood pressure normally falls 10–20% during sleep. When this nocturnal dip is absent, cardiovascular and renal risk increase substantially — even if daytime readings appear normal. This article explains the mechanism and evidence-based management strategies.

Orthostatic Intolerance in Aging: Causes, Risks, and Evidence-Based Management
Orthostatic intolerance — dizziness or near-fainting upon standing — affects up to 20% of adults over 65 and substantially increases fall risk. This article reviews the mechanisms and evidence-based management strategies.

Sodium-Potassium Balance in Aging: The Dietary Lever for Blood Pressure and Vascular Health
The ratio of dietary sodium to potassium is a more powerful predictor of cardiovascular risk than sodium intake alone. This article reviews the evidence for the Na/K balance as a therapeutic target and practical approaches to correction.
