It affects up to one in five adults, and it is a common ailment diagnosed by primary care physicians and specialists. Moreover, it can be a real pain in the neck, or chest rather. I'm talking about gastroesophageal reflux. This big word does not have to be a big deal. Simple lifestyle changes and, in some cases, medication can treat it. So just what is gastroesophageal reflux?
Gastroesophageal reflux is the backflow of acid and other contents from your stomach into the tube the connects the stomach to your mouth, called the esophagus. This reflux can occur naturally on occasion, but when it happens frequently, it can cause problems.
When the backwash of acid and undigested food particles flows back out of the stomach, it can damage the lining of the esophagus. You see, the stomach has a protective lining inside that protects the underlying tissues from the strong stomach acid and other substances that you may eat. Unfortunately, the esophagus does not have that same protection. The harsh back-flow can eat away the esophagus' smooth muscle tissue.
There is a valve at the bottom of your esophagus where it connects to the stomach. It is called the lower esophageal sphincter, or LES. This LES closes after food enters the stomach to prevent it from coming back up. Additionally, your diaphragm is a muscle above the stomach that also helps to support the valve. Sometimes the sphincter relaxes, and stomach contents can escape.
Normal reflux can occur after meals and does not last long. This event rarely occurs when lying down or during sleep.
Abnormal reflux lasts longer and causes troublesome symptoms. Many report feeling discomfort at night when they lay down, rather than just after meals. Chronic reflux causes damage to the digestive system tissues.
If you suspect that you have abnormal reflux or gastroesophageal reflux disease, read on to learn what you can do about it and where to find a quiz to see if you might have reflux.
Gastroesophageal reflux disease (GERD) is caused by the reflux of stomach acid and contents into the esophagus. This condition is related to several factors:
Proton pumps in the stomach wall create enzymes which make stomach acid to break down the food we eat. When they overproduce, reflux is more likely to occur. Coffee is known to increase stomach acid production. Stress also increases stomach acid production. Therefore these can be risk factors for GERD.
The lower esophageal sphincter (LES) closes off the bottom of the esophagus to prevent back-splash. When the muscle tone is relaxed, then the door is not fully closed, and juices can seep back out of the stomach. Smoking and drinking alcohol and caffeinated beverages both contribute to decreased LES tone. These are also risk factors for GERD.
Furthermore, chocolate and mint are known to relax the lower esophageal sphincter.
Moreover, pregnant women have increased progesterone levels. This hormone affects the LES as well.
Two factors that cause increased intra-abdominal pressure are obesity and pregnancy. These both put pressure on the abdominal organs and can lead to gastroesophageal reflux.
An article published in the Gastroenterology Clinics of North America found that obesity, defined as a BMI > 30, was a significant risk factor for reflux and esophagitis (inflammation of the esophagus). The study showed that over one-fourth of participants had weekly reflux symptoms.
A recent study on GERD in pregnancy showed that over 50% of women report reflux symptoms while they are expecting. This can be related to hormonal changes in pregnancy slow digestion and delay stomach emptying.
Reflux can be aggravating and cause symptoms such as:
Less likely but possible signs and symptoms include:
Knowing what we know about reflux and how it happens, there are some simple lifestyle changes you can make if you are suffering from GERD signs and symptoms.
Choose small proportions. Avoid high-fat meals because the fats require the stomach to produce more acid and take longer to digest. Spicy foods (like tomatoes and oranges) can also aggravate reflux.
Maintain a healthy weight.
Sleep habits: Firstly, also avoid eating within three hours of bedtime. Do not lie down after eating. Give your body time to digest the meal.
It can also be helpful to raise your head while resting to let gravity keep the stomach contents down. You can use extra pillows or even raise the head of your bed six to eight inches with bed risers or blocks.
Avoid toxins that could be aggravating your digestion, such as nicotine, alcohol, or excessive caffeine]
Over the counter proton pump inhibitors (PPIs) decrease stomach acid production and may provide some relief. Available options include:
Warning: Do not take these for more than 14 days without talking to your doctor.
There are some urgent signs and symptoms that warrant immediate medical attention. You should call your doctor or seek urgent care for these:
Less serious signs and symptoms that could be related to reflux but should be checked out by a doctor include:
