Frequent, small meals should be eaten rather than three large meals, and the last meal of the day should be early in the evening at least three hours before bedtime. Women who are pregnant and have heartburn should not lie down soon after a meal. Slow down when you eat. Eating too quickly can lead to heartburn. Eating slowly can keep you from becoming too full, which can also result in heartburn. Try not to drink large amounts of liquids after the last meal of the day because the more empty the stomach is at bedtime, the less likely there will be reflux of acid.Sip liquids instead of drinking large glasses of liquids at once.adding Ginger to ur diet also helps. Just cut some ginger and add lemon and black salt to it. Have a couple of pieces after dinner abd lunch. Other home and natural remedies for heartburn include apple cider vinegar, 2-3 teaspoons in an 8-ounce glass of water. It is believed that even though apple cider vinegar is acidic, it helps balance the acid production in the stomach or buffer the acid activity. There is no evidence that homeopathic remedies work to treat heartburn during pregnancy. If you are interested in trying a homeopathic remedy, talk to your doctor first, and consult a registered homeopath. Hope this helps.
