From an Ayurvedic perspective, your symptoms—slow digestion, gas, bloating, delayed bowel clearance, and headaches—suggest Mandagni (low digestive fire) with Vata-Kapha imbalance affecting the gastrointestinal tract. Hypothyroidism often resembles a Kapha-dominant condition in Ayurveda, leading to sluggish metabolism and slower gut motility. Ayurvedic Recommendations 1. Strengthen Agni (Digestive Fire) Take fresh ginger (1–2 thin slices with a pinch of rock salt and a few drops of lemon) 10–15 minutes before meals. Sip warm water throughout the day; avoid iced drinks. Use digestive spices regularly: cumin, coriander, fennel, ajwain, black pepper, and dry ginger. 2. Improve Gut Motility and Bowel Clearance At bedtime, consider Triphala churna (3–5 g with warm water), if suitable for you. Soak 5–7 raisins overnight and consume them in the morning. Establish a fixed time for bowel evacuation each morning, preferably after warm water. 3. Dietary Guidelines Favor warm, freshly cooked foods such as soups, stews, cooked vegetables, and mung dal. Reduce heavy, oily, fried, cheese-rich, and excessively fatty foods, as you already notice they worsen symptoms. Limit eating late at night and avoid overeating. Include lightly cooked vegetables, especially bottle gourd, ridge gourd, pumpkin, and leafy greens. 4. Lifestyle Support Take a 15–20 minute walk after meals, especially after dinner. Practice gentle yoga such as Pawanmuktasana, Vajrasana (after meals), and Marjariasana (Cat-Cow stretch). Maintain regular sleep and meal timings. 5. Helpful Ayurvedic Formulations Depending on your constitution and medical history such as Hingvashtak Churna, Avipattikar Churna, Triphala, or Chitrakadi Vati to improve digestion and reduce bloating.
