Having these chronic symptoms for 10?12 years suggests a functional issue like Irritable Bowel Syndrome (IBS) or food sensitivities. Please consult a doctor for a proper diagnosis, including thyroid and celiac tests. For temporary relief, generic medicines can help: try omeprazole or famotidine for acidity, and psyllium husk or polyethylene glycol for constipation and bloating. Ensure you drink plenty of water and eat a high-fiber diet to help with energy levels and digestion. Since this is long-standing, a structured treatment plan from a physician is the safest approach to long-term recovery without panic.
