What causes Heartburn?
The basic cause of heartburn is when your lower esophageal sphincter (LES) becomes weakened or relaxes abnormally.
The LES is a circular band of muscle at the bottom of your esophagus.
It acts like a 'valve' in the esophagus just as it enters the stomach.
Normally when you swallow, your LES relaxes to let food and liquid flow down into your stomach.
Then it closes again.
However, in some people the LES may open too often or not close tight enough.
When this happens the acid in your stomach can flow back up into your esophagus.
Since your esophagus doesn't have the same protective lining your stomach does, the acid can irritate its more sensitive tissues.
This can trigger heartburn discomfort.
Heartburn foods to avoid
Although the actual cause of heartburn is physical, people generally see heartburn triggers as their heartburn cause.
Food is often a heartburn trigger. In fact, 94% of adults surveyed believed over-eating is a heartburn cause.
Check this list of common heartburn foods to see if any could be triggering your heartburn:
- Tomatoes, tomato sauce and ketchup.
- Oranges, grapefruit and other citrus fruits and juices
- Coffee, tea or other caffeinated products
- Fried & Fatty foods
