8. Trouble Concentrating or Brain Fog
Words jumble in meetings, your once-sharp focus now a hazy drift, like thinking through cotton. Urea buildup clouds cognition, an early cognitive hit. A 2023 study in Kidney International links mild CKD to 25% higher fog risk. Anna, 50, blamed menopause for her forgetfulness—nephrologist tests proved otherwise. Lifestyle tweaks cleared the mist. Foggy days more often? The sleeper hit’s up next.
9. Persistent Headaches That Linger
Dull throbs behind your eyes, unrelenting despite rest or pills, stealing your calm. Fluid and toxin shifts strain vessels, sparking vascular headaches. Times of India reports headaches as a masked early failure cue. David, 54, powered through “tension” headaches until scans showed hypertension-fueled damage. BP control banished them. Head pounding now? One more to watch.
10. Frequent Infections or Slow Healing
Colds drag on, cuts linger longer than they should, your body fighting battles it once won easily. Weakened immunity from protein loss leaves you vulnerable. Iowa Clinic notes recurrent UTIs as a stealthy progression marker. Elena, 59, shrugged off endless sniffles until urine tests revealed silent leaks. Antibiotics and monitoring healed the pattern. Bugs biting more? This could be life-altering.

| Nausea | Food aversion | Gut irritation | Log meal reactions |
