Acid reflux occurs when the lower oesophageal sphincter (LES) is weak. LES is a muscle ring that divides the oesophagus and stomach. Therefore, if the LES can not close tightly after you swallow food or fluids, the food particles will move back to your throat.

Acid reflux symptoms include:

  • repeated vomiting
  • asthma

There are several reasons for a weak lower oesophageal sphincter (LES). If you have a bad LES, you can encounter more reflux problems if you eat or drink the following foods and beverages:

  • garlic
  • spicy foods
  • onions
  • mint
  • grapefruit
  • lemons
  • limes
  • alcohol
  • pineapple
  • chocolate
  • salsa
  • acidic drinks
  • coffee
  • caffeine
  • orange juice or oranges
  • carbonated beverages
  • tomato sauce or tomatoes

People who have acid reflux also receive a bitter taste in their mouth. Usually, the taste can cause nausea and bad breath, along with the constant burping and coughing associated with reflux and GERD. Another symptom of reflux and GERD that can lead to nausea is the feeling of stomach acid, an irritating in the oesophagus.

Some chewable antacids contain ingredients that freshen up the air and can reduce all symptoms at once. Other acid reflux and GERD drugs can cause dry mouth. However, dry mouth occurs when the salivary glands do not contain enough saliva. It can be sticky, and it can also cause a bad breath. Therefore, ask your doctor about dry mouth remedies and the side effects of all medications you take. Many people are not helped by lifestyle changes or medications. GERD surgery may be a choice for these people.
