What is swallowing difficulty?
The act of swallowing involves several organs of the digestive system, including the mouth, throat, pharynx and esophagus. It begins during mastication, or chewing of food, which is part of mechanical digestion. Your saliva contains enzymes that break down or emulsify food into a soft mass that can travel down the esophagus, the tube connecting your mouth to your stomach. Swallowing is partly voluntary, occurring at your command, and partly involuntary, controlled by muscles and nerves.
Problems during any stage of this process can cause swallowing difficulty or pain occurring in the throat, chest or neck. You may feel pressure, heaviness, or the sensation of choking. It can also result in regurgitation or vomiting. The medical term for difficulty swallowing is dysphagia.
Swallowing difficulty can indicate a serious problem. Seek immediate medical care (call 911) if you experience painful swallowing accompanied by difficulty breathing, choking, vomiting blood, or stools that are bloody, black or tarry.
What other symptoms might occur with swallowing difficulty?
Swallowing difficulty may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. Symptoms that frequently affect the digestive tract may also involve other body systems.
Gastrointestinal symptoms that may occur along with swallowing difficulty
Dysphagia may accompany other symptoms affecting the gastrointestinal system including:
- Abdominal or stomach pain
- Bad breath
- Foul or sour taste in the mouth
- Nausea with or without vomiting
- Painful swallowing
- Reflux (backflow) of food
Other symptoms that may occur along with swallowing difficulty
Dysphagia may accompany symptoms related to other body systems including:
Serious symptoms that might indicate a life-threatening condition
In some cases, difficulty swallowing may be a symptom of a life-threatening condition that should be immediately evaluated in an emergency setting. Seek immediate medical care (call 911) if you, or someone you are with, have any of these life-threatening symptoms including:
What causes swallowing difficulty?
Difficulty with swallowing can have a number of causes, including infections, conditions specific to the esophagus (the tube connecting your mouth to your stomach), and mechanical obstructions such as food or an object caught in your throat.
Infectious or inflammatory causes of swallowing difficulty
Dysphagia may be caused by infections or inflammation including:
Gingivitis (inflammation of the gums)
Ulcers in the mouth or throat
Esophageal causes of swallowing difficulty
Dysphagia can also be caused by esophageal conditions including:
Achalasia (disorder of the esophagus that impairs its ability to propel food down to the stomach)
Erosive esophagitis (inflammation of the esophagus)
Esophageal narrowing due to radiation, chemicals or medications
Nutcracker esophagus (disorder characterized by abnormal contraction of the muscles of the esophagus)
Schatzki’s ring (abnormal ring of tissue in the lower esophagus)
Neurological and muscular causes of swallowing difficulty
Neurological and muscular conditions causing dysphagia include:
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, a severe neuromuscular disease that causes muscle weakness and disability
Muscular dystrophy (inherited disorder that causes a progressive muscle weakness and loss of muscle tissue)
Parkinson’s disease (brain disorder that impairs movement and coordination)
Polymyositis (widespread inflammation and weakness of muscles)
Serious or life-threatening causes of swallowing difficulty
In some cases, difficulty swallowing may be a symptom of a serious or life-threatening condition that should be immediately evaluated in an emergency setting. These include:
Food or object stuck in your throat
Tumors of the mouth, throat or esophagus
Questions for diagnosing the cause of swallowing difficulty
To diagnose your condition, your doctor or licensed health care practitioner will ask you several questions related to your swallowing problems including:
How long have you felt difficulty swallowing? Has it gotten better over time or worse?
Is the difficulty limited to swallowing certain foods?
Does the difficulty occur when swallowing liquids, solids, or all substances?
Is your throat sore, or does it feel like there is a lump?
Have you been ill recently with symptoms such as coughing or chest irritation?
Could you have inhaled or swallowed something that is irritating your throat?
Do you have any other symptoms?
Do you have any other medical problems?
What medications do you take?
Because dysphagia can be due to a serious disease, failure to seek treatment can result in serious complications and permanent damage. Once the underlying cause is diagnosed, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce the risk of potential complications including:
Development of esophageal cancer
Permanent damage to the throat or esophagus
