Silent reflux

Overview

Silent reflux, also called laryngopharyngeal reflux (LPR), is a condition where stomach acid flows back up into the throat and voice box. Unlike typical acid reflux, it often doesn't cause heartburn, so people may not know they have it.

Yes, silent reflux is quite common. Many people experience it, especially those with risk factors like obesity or a hiatal hernia.

It can affect anyone, but it is more common in adults over 50, pregnant women, and people who are overweight or have a hiatal hernia. It also occurs in infants and children.

Symptoms

Common symptoms

• Hoarseness or a raspy voice, especially in the morning
• A chronic cough that doesn't go away
• A feeling of a lump in the throat (globus sensation)
• Trouble swallowing or feeling like food gets stuck
• Excess throat clearing or a sensation of post-nasal drip

Symptoms in children

• Frequent ear infections or sinus infections
• Asthma-like symptoms, such as wheezing or shortness of breath
• Feeding difficulties, spitting up, or refusing to eat
• Persistent cough or hoarse cry

Symptoms in older adults

• More severe hoarseness and voice changes
• Chronic throat clearing or coughing
• Increased risk of aspiration (food or liquid going into the lungs)
• Worsening of existing conditions like asthma or sleep apnea

Causes

Main causes

• A weak or relaxed lower esophageal sphincter (the muscle that keeps stomach contents from flowing back up)
• A hiatal hernia, where part of the stomach pushes up into the chest
• Increased pressure in the abdomen from obesity, pregnancy, or straining

Risk factors

• Being overweight or obese
• Pregnancy
• Smoking or exposure to second-hand smoke
• Drinking alcohol or caffeinated beverages
• Eating large meals or lying down soon after eating
• Consuming spicy, fatty, or acidic foods

When to see a doctor

See a doctor urgently if:

• Severe chest pain or difficulty breathing
• Vomiting blood or passing black stools
• Signs of choking or aspiration

Book a routine appointment if:

• Hoarseness or cough that lasts longer than a few weeks
• Frequent sore throat or feeling of a lump in the throat
• Trouble swallowing that comes and goes

Diagnosis

A doctor will listen to your symptoms and examine your throat. They may use a small camera to look at your voice box and throat (laryngoscopy). Other tests can measure acid in your throat.

Tests that may be done

• Laryngoscopy: A thin, flexible tube with a camera is passed through your nose to look at your voice box and throat.
• pH monitoring: A small tube or device measures acid level in your throat over 24 hours.
• Esophagram: You swallow a chalky liquid that shows up on X-rays to see how your throat works.

What to expect at your appointment

Most tests are quick and not painful. For laryngoscopy, a numbing spray is used in your nose. pH monitoring may involve wearing a small monitor for a day. Your doctor will explain what to expect before each test.

Treatment

Treatment aims to reduce the amount of acid that reaches your throat and protect tissues from damage. It usually starts with lifestyle changes and may include medication if needed.

Self-care at home

• Eat smaller, more frequent meals—don't overfill your stomach.
• Avoid trigger foods: spicy, fatty, acidic, or fried foods, and limit caffeine and alcohol.
• Don't lie down for at least 2 to 3 hours after eating.
• Elevate the head of your bed by 6 to 8 inches (use blocks or a wedge pillow).
• Lose weight if you are overweight.

Medical treatments

Doctors may recommend medications that reduce stomach acid, such as proton pump inhibitors or H2 blockers. They can also prescribe medicines that help empty the stomach faster. Always take medications as prescribed and discuss any side effects with your doctor.

When is surgery considered?

If lifestyle changes and medications don't control your symptoms, a surgeon may tighten the muscle between the stomach and esophagus (fundoplication). This is usually only considered for severe cases.

Living with this condition

Living with silent reflux means being mindful of what you eat and how you eat. Small changes, like eating earlier in the evening and avoiding trigger foods, can make a big difference. Stick with your treatment plan and see your doctor regularly.

Lifestyle tips

• Eat your last meal at least 3 hours before bedtime.
• Avoid bending over or heavy lifting after meals.
• Wear loose-fitting clothes that don't press on your belly.
• Quit smoking if you smoke.

Diet and exercise

A balanced, low-acid diet helps. Focus on vegetables, lean proteins, and whole grains. Avoid citrus, tomatoes, onions, garlic, and high-fat foods. Exercise regularly, but avoid exercises that put pressure on your abdomen, like crunches or heavy weightlifting, right after eating.

Mental health and emotional wellbeing

Living with a chronic condition like silent reflux can cause stress, anxiety, or disrupted sleep. It's normal to feel frustrated. Talk to your doctor if these feelings affect your daily life. Counseling or support groups can help.

Prevention

Not always, but you can lower your risk by maintaining a healthy weight, eating smaller meals, avoiding trigger foods, and not lying down after eating. These habits help prevent reflux from starting or getting worse.

Complications

If left untreated

• Esophagitis (inflammation of the esophagus)
• Barrett's esophagus (changes in the lining of the esophagus that can lead to cancer)
• Voice box damage, including ulcers or granulomas
• Aspiration pneumonia (from stomach contents entering the lungs)

Long-term outlook

With proper treatment and self-care, most people with silent reflux can manage their symptoms well and prevent complications. It may take time to find the right combination of lifestyle changes and medications, but many people live comfortably with the condition.
