According to Google, in a short term heartburn means a form of indigestion caused by acid regurgitation into the esophagus, you feel such uncomfortably hot and burning pain in your esophagus. It's quite annoying, really. I had it during my pregnancy for the last 7 months (and it's common for pregnant women - especially those with short tall, also common for people have heartburn occasionally). Heartburn isn't the same as heart disease. Although the common name for this ailment is heartburn but the condition has nothing to do with the heart. Since the pain is felt around the chest area, people often mistake it for the onset of a heart attack.
Many times I went to the doctors for medical help and the results were just nothing, they only suggested me to avoid such food which increases acidity like too much oily or spicy stuffs, do not take large amount of food at a time, no caffeinated drinks/donuts/chocolates and intake of more water will keep it better. Again the results were just nothing.
Thanks God after suffered for months with a heartburn, accidentally I found out the natural cures for heartburn. Just simply take a glass of cold UHT Milk everytime you have it, believe me...it greatly works...rather than some prescriptions that doctors given. However if your heartburn symptoms are experienced frequently and start affecting your daily routine, you should check with a doctor in case it's a
sign of something more serious...well hopefully not.
