Night-time dry mouth with dry palms/soles despite adequate water intake suggests mouth breathing during sleep, dehydration at night, medication side effects, anxiety/stress,
thyroid problem, or salivary gland issue.
Diabetes seems unlikely if sugars are normal.
Next Steps
• Avoid mouth breathing → check for snoring, nasal blockage, or sleep apnea
• Use saliva substitute gel/spray at night
• Apply thick moisturizer (petroleum jelly/urea-based cream) to hands & feet before sleep
• Get tests:
TSH (
thyroid), CBC,
electrolytes,
kidney function
• ENT or physician review if persists
Health Tips
• Avoid caffeine, alcohol, smoking at night
• Keep water beside bed, take small sips
• Use room humidifier
• If dryness worsens or eye dryness/joint pain occurs → evaluate for Sjogren’s syndrome
