Episode description
- Antidepressants like SSRIs are strongly linked to hyponatremia, a dangerous drop in blood sodium that disrupts nerve and muscle function
- The risk is highest in the first two weeks of treatment, when sodium levels plummet to life-threatening lows that trigger confusion, seizures, or fainting
- Older adults, especially women over 80, are among the most vulnerable, with nearly 1 in 15 experiencing profound sodium loss after starting these drugs
- Symptoms of drug-induced low sodium often mimic worsening anxiety or depression, leading to misdiagnosis and unnecessary increases in medication
- Natural strategies like optimizing nutrition, restoring key vitamins and minerals, daily movement, sunlight exposure, and restful sleep offer safer ways to support mood and energy without creating sodium imbalances
