what are the causes of heart burn during pregnancy

-Frequent vomiting -As baby grows bigger, the womb compresses the stomach and intestines upwards -The mechanism (muscle) to help prevent reflux doesn’t work so well during pregnancy as the muscle is more relaxed. So if you’re vomiting, avoid acidic and spicy food, as well as drinks (including coffee/tea/carbonated drinks) If your tummy’s getting bigger, take smaller and more frequent meals
