Heartburn & Acid Reflux
Burning sensation in chest or throat, especially after eating or lying down
TL;DR
Reflux is a mechanical problem: stomach contents move up past a weak lower esophageal sphincter. Most cases improve with meal timing, portion size, weight loss and trigger removal before any supplement matters.
Overview
Heartburn is the burning sensation behind the breastbone that happens when acidic stomach contents wash back into the esophagus. Occasional reflux is normal. When it happens twice a week or more, or damages the esophageal lining, it is called GERD. The problem is rarely too much acid. It is usually a lower esophageal sphincter that relaxes at the wrong time, made worse by pressure from large meals, abdominal fat, late eating or lying flat too soon. That is why the highest-yield interventions are structural: smaller meals, a three-hour gap between the last meal and bed, raising the head of the bed by six to eight inches, and losing abdominal weight if it is present. Acid-suppressing medication works well for symptom control and healing erosive disease, but it treats the consequence rather than the cause, and long-term use carries tradeoffs for B12, magnesium and iron absorption. Supplement evidence here is thin. Melatonin has small trials suggesting it improves sphincter tone; demulcents such as slippery elm and alginate preparations coat rather than cure. Persistent reflux that does not respond, or comes with difficulty swallowing, weight loss, vomiting or anemia, needs endoscopy rather than another remedy.
Common Symptoms
- •Burning behind the breastbone, often after meals
- •Sour or bitter fluid rising into the throat
- •Worse when lying down or bending forward
- •Chronic dry cough or throat clearing
- •Hoarseness, especially in the morning
- •Sensation of a lump in the throat
Common Causes
- •Transient relaxation of the lower esophageal sphincter
- •Large meals and late-night eating
- •Excess abdominal weight raising intragastric pressure
- •Hiatal hernia
- •Alcohol, nicotine, chocolate, peppermint and coffee in susceptible people
- •Pregnancy
- •Medications including calcium channel blockers, nitrates and NSAIDs
Root Causes
The central defect is inappropriate relaxation of the lower esophageal sphincter, amplified by anything that raises pressure inside the stomach or delays emptying. Abdominal adiposity, hiatal hernia and large late meals are the dominant drivers in most adults.
How It's Diagnosed
Diagnostic Markers
- Clinical diagnosis by symptom pattern in typical cases
- Upper endoscopy when alarm features are present or symptoms persist
- Ambulatory pH or pH-impedance monitoring for unclear cases
- H. pylori testing when ulcer disease is suspected
When to See a Doctor
Seek assessment promptly for difficulty or pain swallowing, unintentional weight loss, vomiting, black stools, anemia, or symptoms starting after age 55. Chest pain that feels like pressure, radiates to the arm or jaw, or comes with sweating or breathlessness is a cardiac emergency until proven otherwise.
Supplements Studied For This
Melatonin
Small trials suggest melatonin improves lower esophageal sphincter pressure and heartburn scores, but the studies are few and mostly from a single research group.
Slippery Elm
Slippery elm coats irritated tissue and may soothe symptoms briefly, but there are no controlled trials in reflux.
Diet & Lifestyle
Suggested Pattern
Smaller, lower-volume meals eaten earlier in the day; identify personal triggers with a two-week diary rather than adopting a blanket elimination list.
Eat more
- Lean proteins
- Non-citrus fruits
- Oats and other soluble-fibre grains
- Cooked vegetables
- Ginger tea
Avoid
- Large late-evening meals
- Alcohol
- Peppermint
- Chocolate
- Fried and very high-fat meals
- Carbonated drinks if personally triggering

Frequently Asked Questions
Who It Affects
Weekly heartburn affects about one in five adults in North America and Europe.
More common with rising body weight, during pregnancy, and in adults over 40.
Quick Facts
- •Affects roughly 20 percent of adults in Western countries
- •Too much acid is rarely the cause; sphincter timing is
- •A three-hour gap before lying down is one of the strongest levers
- •Head-of-bed elevation beats extra pillows, which bend the abdomen
- •Long-term acid suppression can reduce B12, magnesium and iron absorption
