Frequent acidity and gas are commonly due to conditions like Acid Reflux or indigestion, often triggered by irregular meals, spicy or oily foods, overeating, stress, smoking, or excess tea/coffee. Eating too fast, lying down soon after meals, or poor digestion can also contribute. To manage this, try eating small, regular meals, avoiding trigger foods, staying hydrated, eating slowly, and avoiding lying down for at least 2-3 hours after eating. Reducing stress and maintaining a healthy lifestyle also helps. If symptoms are frequent, severe, or associated with weight loss or vomiting, consult a doctor for proper evaluation and treatment.
