Frequent acidity is usually caused by irregular eating habits, spicy or oily foods, excess tea or coffee, stress, or conditions like gastritis or acid reflux. To manage it, try to eat meals on time, avoid trigger foods (spicy, fried, citrus, and caffeine), eat smaller portions, and do not lie down immediately after eating. Maintaining a healthy weight, reducing stress, and avoiding smoking or alcohol can also help. You can use antacids or acid-reducing medicines for relief, but if the problem is frequent or severe, or if you have warning signs like weight loss, persistent vomiting, difficulty swallowing, or black stools, you should consult a doctor for proper evaluation and long-term treatment.

A burning sensation after eating is usually due to acidity or acid reflux. Try eating small, frequent meals, avoid spicy and oily foods, and do not lie down immediately after eating. If symptoms persist, you may need an antacid or doctor's advice for proper treatment.
