What causes GERD?
GERD is usually caused by the ring of muscle at the bottom of the esophagus (known as the lower esophageal sphincter) becoming weaker. The esophagus connects your mouth to your stomach, and this ring of muscle opens and closes to let food in.
If the muscle becomes weaker, it can’t always close as it’s supposed to, and it isn’t able to stop your stomach acid from leaking up your throat. This causes the symptoms of GERD, like heartburn and acid reflux.
What are the symptoms of GERD?
The main symptoms of GERD are heartburn and acid reflux. These cause burning in the chest and throat, often after eating. Sometimes acid reflux comes with a sour taste in the mouth.
There are other symptoms that may appear. These can include oesophagitis, meaning a sore and swollen esophagus. GERD can also appear with:
- bad breath
- bloating and belching
- nausea
- pain when swallowing
- hiccups
- coughing
- bloating
Can GERD lead to other problems?
Usually, GERD causes mild but uncomfortable symptoms. But if GERD is quite severe and untreated for a long period of time, it can cause some complications. These include:
Stomach acid in the throat can eventually begin to damage the lining of the esophagus, leading to ulcers. Ulcers may bleed, cause pain and make it hard to swallow. Many drugs used to treat GERD can also treat or reduce the risk of ulcers.
- Scarred and narrow esophagusÂ
Sometimes damage caused by stomach acid causes scarring and narrowing of the throat. This is also known as esophageal stricture and can make it incredibly difficult and painful to swallow. There is a procedure that widens the esophagus, often by using a small balloon.
Repeated episodes of GERD can sometimes lead to a change in cells that line the lower esophagus. This is known as Barrett’s esophagus. About 6% of people with chronic GERD end up developing Barrett’s esophagus.[1]
There usually aren’t any noticeable symptoms with Barrett’s esophagus. Very rarely, it can be associated with esophageal cancer. A clinician may suggest having an endoscopy every few years to keep an eye on this.
It’s very rare to develop esophageal cancer even if you have Barrett’s esophagus. But having Barrett’s esophagus does make you ten times more likely to develop esophageal cancer.[2]
If you are experiencing any of the above symptoms, you should speak to a doctor. The best thing you can do for your health is to treat your GERD early.
