While you are pregnant, this can be a serious problem. Elevated hormone levels of pregnancy probably cause reflux by lowering the pressure in that part of your body known as the lower oesophageal sphincter. Also, the growing baby puts more pressure on the abdomen. Both of these effects of pregnancy tend to increase the risk of GERD.
If your acid reflux disease is a minor condition, then you should only experience minor symptoms. These would include primarily heartburn, regurgitation, and nausea. However, if the condition is complicated, then watch out for the following symptoms. The liquid that comes back into the oesophagus damages the lining of the oesophagus. The body tries to protect itself from the acid reflux disease by 'inflaming' the oesophagus. Trying to speed the healing process through the inflammation, the wall of the oesophagus may form an ulcer.
The ulcer is a break in the lining of the oesophagus wall. Then
what happens is that there may be bleeding. If the bleeding is very severe,
patients might need a blood transfusion or even surgical treatment.If your heartburn is severe or
acute, happening very frequently, you need to see a doctor.What can you do for yourself to help the
condition? Try sleeping a pillow a night that raises your chest up slightly
so that gravity can bring the acid back down more easily. Since this
condition usually occurs on a full stomach, eat earlier and eat less to keep the stomach from being
too full.
Ease off on the chocolate, peppermint, alcohol, and caffeinated
drinks. Reduce fatty foods and of course, cut down or quit
smoking. Other foods may aggravate the conditions. Avoid spicy or acid-containing foods, like citrus
juices, carbonated beverages, and tomato juice.
