Acid reflux affects up to 14% of the world’s population. There is a common misconception that acid reflux is caused solely by overconsumption of acidic foods and drinks, such as citrus fruits or coffee. There is more to what triggers acid reflux than meets the eye. While your diet can be highly impactful in preventing acid reflux, there are more factors to consider - for example, what you do after you finish a meal, your sleeping habits, and more.
While there are over-the-counter medications you can take for acid reflux, there is a vast range of preventive methods you should include in your daily routine to alleviate persistent heartburn. In this article, you will find information about the causes of acid reflux, the lifestyle changes that help prevent it, and home remedies for persistent heartburn.
Gastroesophageal reflux disease (GERD)
Acid reflux occurs when acid in your stomach backflows up into the oesophagus. Symptoms of acid reflux (or gastroesophageal reflux disease – GERD) can include heartburn (burning/heat sensation in the mid-chest), regurgitation of food or sour liquid towards the neck, bitter taste in the mouth, sore throat, voice hoarseness or chronic cough.
You shouldn't be too alarmed if you’re having these symptoms periodically! Mild cases of acid reflux happen to most adults, primarily when a balanced diet and exercise routine haven’t been maintained recently. Frequent or chronic heartburn may however cause inflammation, bleeding and narrowing of the esophagus, and increase the risk of esophageal cancer.
What causes acid reflux?
Acid reflux is actually caused by excessive relaxation or weakening of a muscle in the lower esophagus called the lower esophageal sphincter, which normally prevents backward flow of stomach contents in the esophagus.
Certain foods may relax the sphincter and predispose to acid reflux, such as spices, citrus and fatty foods, and carbonated, caffeinated, alcoholic beverages. Other conditions like being overweight or pregnancy increases risk of acid reflux because of the additional pressure on the abdomen.
What are remedies for Acid Reflux?
Lifestyle changes relating to the above factors can help acid reflux. Some people with mild heartburn may find these changes sufficient to eliminate their symptoms.
- Minimize potentially triggering foods: spices, citrus and fatty foods, as well as carbonated, caffeinated, alcoholic beverages
- Eat slowly
- Avoid lying flat within 3-4 hours after eating a meal
- Stop smoking
- Maintain a healthy body weight
When lifestyle changes are not enough to control acid reflux symptoms, over-the-counter products can be used for infrequent symptoms. Prescription medications that reduce stomach acid secretion are effective for more frequent symptoms.
When to see a doctor
Symptoms of acid reflux can be well controlled. If your symptoms affect your quality of life, you should contact a doctor and discuss a treatment plan. Symptoms of complications from chronic heartburn include the following, and an upper endoscopy under sedation should be considered.
- Severe chest pain
- Vomiting of blood
- Difficulty with or pain in swallowing
- Unintentional weight loss
