Gastroesophageal reflux disease (GERD) is a chronic condition where stomach acid flows back into the oesophagus, causing a painful burning sensation in the chest, known as heartburn. Occasional reflux is normal, but when it occurs regularly, it can have serious consequences. Acid reflux can be triggered by a large meal, lying down after eating, or wearing tight clothing. While it can occur at any time of day, many people experience worsened acid reflux at night. This is because when lying down, gravity no longer helps keep stomach acid down, and saliva production, which neutralises stomach acid, is reduced during deeper stages of sleep. This combination can cause acid to remain in the oesophagus for longer, leading to more severe symptoms, including choking and coughing. Inhalation of acid reflux during sleep can cause aspiration, where acid is breathed into the lungs, and choking, where acid enters the throat.

What You'll Learn
The risk of choking and aspiration
Gastroesophageal reflux disease (GERD) is a chronic condition where stomach acid flows back into the oesophagus, causing a painful burning sensation in the chest, known as heartburn. GERD can be aggravated by certain foods, drinks, smoking, and wearing tight-fitting clothes, especially around the waist and abdominal area. It is also more likely to occur when lying down because gravity no longer helps keep stomach acid down.
If acid reflux reaches the throat or larynx, it can cause coughing and choking. During sleep, there is also a dangerous risk of aspirating the acid into the respiratory system. This can cause asthma-like symptoms such as chronic coughing, wheezing, and shortness of breath. Tiny acid particles may irritate the bronchial tubes and cause them to contract, leading to breathing difficulties.
To reduce the risk of choking and aspiration, it is recommended to avoid trigger foods, not eat right before bedtime, change sleep positions, wear loose-fitting clothing, quit smoking, and maintain a healthy weight. Elevating the head while lying down can also help improve sleep for those with GERD. Sleeping on the left side is specifically recommended as it reduces reflux episodes and exposure of the oesophagus to stomach acid.

Lifestyle changes to reduce acid reflux
Inhaling acid reflux while sleeping can cause aspiration, which is when food or fluid is accidentally breathed into the lungs. This can lead to choking and a feeling of coughing. If acid particles enter the airways, they can cause them to contract, resulting in coughing and breathing difficulties. Chronic acid reflux can also lead to inflammation and ulcers in the oesophagus, scar tissue that narrows the oesophagus, chronic cough, damage to teeth, and exacerbated asthma symptoms.
Sleeping position
Sleeping on your left side can help reduce reflux episodes and exposure of the oesophagus to stomach acid. Sleeping on your back, for example, can make reflux more likely. Elevating the head of the bed by at least 6 inches can also help reduce acid reflux. Avoid using piles of pillows as this can put pressure on your stomach and make reflux worse.
Clothing
Tight-fitting clothing, especially around the waist and abdominal area, can put pressure on the stomach and push its contents back up into the oesophagus. Wear loose-fitting and comfortable clothing to help reduce acid reflux.
Eating habits
Allow enough time for your food to digest and empty from your stomach by eating meals at least 2 to 3 hours before lying down or going to bed. Avoid large meals, especially late in the day, as they can put pressure on the lower oesophageal sphincter (LES). Eat smaller meals and slowly, and avoid bedtime snacks.
Trigger avoidance
Certain foods and drinks can trigger acid reflux, including alcohol, coffee, tea, cola, tomato juice, citrus juice, fatty foods, onions, and chocolate. Avoid eating or drinking these before lying down or exerting yourself. Smoking can also trigger acid reflux, as nicotine weakens the LES.
Weight loss
Being overweight can promote reflux, as excess abdominal fat puts pressure on the stomach. Losing weight can help reduce reflux symptoms.

The link between obesity, weight gain and GERD
Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach acid flows back into the oesophagus, causing symptoms such as heartburn, regurgitation, and sore throat. Occasional episodes of reflux are normal, but when they occur regularly, they can have serious consequences and are classified as GERD.
GERD can disrupt sleep due to nighttime acid reflux symptoms. Reflux tends to worsen when lying down because gravity no longer aids in keeping stomach acid down. In addition, saliva production, which typically neutralises stomach acid, decreases during deeper stages of sleep. As a result, stomach acid can remain in the oesophagus for longer, leading to more severe GERD symptoms and potentially disturbing sleep.
Now, let's discuss the link between obesity, weight gain, and GERD:
Obesity and weight gain have been linked to an increased risk of developing GERD and experiencing more severe symptoms. Studies have shown a direct correlation between an individual's body mass index (BMI) and the likelihood of developing GERD. Even moderate weight gain can increase the risk of GERD, and the risk appears to increase progressively with weight gain. This association is particularly notable in women, suggesting a potential role for estrogen in the development of GERD.
Abdominal obesity, specifically, is believed to be a significant factor in the link between obesity and GERD. Carrying extra weight around the abdomen increases intra-abdominal pressure, pushing the stomach and its contents upwards. This increased pressure can promote reflux by causing disruptions at the esophagogastric junction and increasing gastroesophageal pressure gradients. Additionally, obesity-related pathophysiological disturbances, such as oesophageal motor disorders, lower oesophageal sphincter abnormalities, and hiatal hernias, can further contribute to the development of GERD.
Weight loss has been shown to be an effective strategy for reducing GERD symptoms in obese individuals. Lifestyle changes, including dietary modifications and regular exercise, are typically recommended as the first line of treatment. If these approaches are unsuccessful, weight loss surgery, such as bariatric surgery, can be considered.

The impact of acid reflux on sleep quality
Acid reflux, also known as gastroesophageal reflux, is a backflow of acid from the stomach into the oesophagus. This can cause heartburn and other symptoms. Occasional episodes of reflux are normal, but when they occur regularly, they can have serious consequences and are known as gastroesophageal reflux disease (GERD).
GERD can significantly impact sleep quality. Firstly, reflux is worse when lying down because gravity no longer helps keep stomach acid down. This means that acid can remain in the oesophagus for longer, causing more severe symptoms. In addition, saliva production, which usually helps neutralise stomach acid, is reduced during deeper stages of sleep. With less saliva and decreased swallowing during sleep, it becomes more difficult for the body to push acid reflux back into the stomach. This can lead to aspiration (the accidental breathing in of stomach acid into the lungs) or choking. Waking up choking on stomach acid can be a frightening experience and can interrupt sleep.
Research has found a correlation between GERD and lower sleep quality. Sleep disturbances may induce or worsen gastrointestinal symptoms, and vice versa. Conscious awakenings during sleep due to reflux can lead to hyperarousal, which is associated with increased sympathetic activation, such as a higher heart rate and blood pressure. This can result in poor sleep quality.
GERD can also trigger asthma-like symptoms such as chronic coughing, wheezing, and shortness of breath. If acid particles enter the airways, they can cause them to contract. Sleep deprivation can also impact GERD, as a lack of sleep can cause increased sensitivity to acid in the oesophagus. This can worsen the quality of life for people with GERD.
There are several ways to improve sleep quality for people with GERD. Getting a good night's rest can help to prevent symptoms and improve quality of life. Sleeping on the left side can reduce reflux episodes and exposure of the oesophagus to stomach acid. Elevating the head while lying down can also help, as can allowing more time for food to digest before lying down. Wearing loose-fitting clothing and avoiding trigger foods can also help reduce symptoms.

Treatment options for acid reflux
Acid reflux, also known as gastroesophageal reflux, is a backflow of acid from the stomach into the oesophagus. While occasional episodes of reflux are normal, when they occur regularly, they can have serious consequences and are known as gastroesophageal reflux disease (GERD). GERD can cause severe symptoms such as inflammation and ulcers in the oesophagus, damage to teeth, and even exacerbate asthma symptoms. Therefore, it is important to explore treatment options to manage acid reflux effectively.
Lifestyle Changes
Doctors often recommend lifestyle changes as the first step in treating GERD. These changes can include:
- Losing weight if overweight or obese
- Elevating the head during sleep by using a foam wedge or extra pillows to raise the head and upper back off the bed by 6 to 8 inches
- Quitting smoking
- Changing eating habits and diet, such as eating smaller meals, avoiding large or fatty meals, and not lying down too soon after eating
- Wearing loose-fitting clothing, especially around the waist and abdominal area
- Finding ways to relax and destress, such as through meditation, breathing exercises, or talking to a friend or therapist
Medication
In addition to lifestyle changes, doctors may prescribe medication to manage GERD symptoms. Over-the-counter antacids can be effective for intermittent and infrequent symptoms, but they may worsen the problem if taken frequently. Other medications include:
- Histamine 2 (H2) blockers: These drugs help lower acid secretion and heal esophageal erosions.
- Proton pump inhibitors (PPIs): PPIs are more effective than H2 blockers in suppressing acid production and can heal erosive oesophagitis. They are generally safe and effective, but side effects may include headaches, diarrhoea, and upset stomach.
- Prokinetic agents: These drugs enhance the activity of the smooth muscle of the gastrointestinal tract and are sometimes prescribed in combination with an acid-suppressing drug.
Surgery
In some cases, GERD may require surgical intervention, especially if it is severe or unresponsive to medication. The most common surgery is fundoplication, where a surgeon sews the top of the stomach around the end of the oesophagus to add pressure to the lower oesophageal sphincter and prevent reflux. Weight-loss surgery may also be recommended for patients with GERD and obesity.
