Your observations strongly suggest a chronic Vata–Pitta Grahani pattern where both doshas are disturbing each other simultaneously.
Pitta is causing gut irritation, loose/sticky stools, skin flare-ups, and sensitivity to heating medicines.
Vata is causing irregular digestion, bloating, shapeless stools, coldness, dryness, and instability.
This is why:
Strong heating herbs improve digestion temporarily but aggravate Pitta and loosen motions.
Excess cooling herbs calm Pitta but weaken Agni, causing heaviness and sticky stools.
In Ayurveda, this condition usually requires “Deepana without excess heat + Grahi without excessive dryness + gentle Vata balancing.”
Your experience with mild heating before food and Bilvadi after food actually reflects this principle well.
Ayurvedic Management Approach
Focus on stabilizing Agni, not aggressively increasing it.
Helpful Measures
Eat warm, freshly cooked, light but nourishing meals
Avoid fasting, overeating, cold foods, curd at night, fried food, tea/coffee excess, and very spicy foods
Use small frequent meals instead of large meals
Maintain regular meal and sleep timings
Herbs Commonly Used in Such Patterns
Bilva / Bilvadi – helps Grahani and stool formation
Dadimashtaka Churna – supports digestion without excessive heat
Guduchi (Giloy) – balances Pitta gently
Shatavari or Yashtimadhu – soothe gut irritation in selected patients
Mild Vata-calming support with small quantity ghee may help dryness and instability
