What is Dysphagia? Signs, Causes and When to Get Help

Dysphagia is the medical term for difficulty swallowing. It's more common than most people realise - affecting around 8% of the global population - and yet it's often misunderstood, under-reported, or dismissed. If you or someone you care for is having trouble swallowing, this article explains what's happening and what to do about it.

What is swallowing?

Swallowing seems simple, but it's actually one of the most complex motor tasks the human body performs. It involves over 30 pairs of muscles working in precise coordination across three phases - the oral phase (chewing and preparing food), the pharyngeal phase (moving food through the throat), and the oesophageal phase (food travelling to the stomach).

When any part of this process is disrupted, dysphagia can occur.

Signs of dysphagia

Dysphagia can affect eating, drinking, or both. Common signs include:

• Coughing or choking during or after eating or drinking
• A sensation of food or liquid sticking in the throat or chest
• Needing to swallow multiple times to clear food
• A wet or gurgly voice quality after eating or drinking
• Avoiding certain foods or drinks - particularly thin liquids or hard textures
• Taking much longer than usual to eat a meal
• Unexplained weight loss or dehydration
• Recurrent chest infections (which can indicate that food or liquid is entering the airway)
• Drooling or difficulty managing saliva

Not everyone with dysphagia experiences all of these. Some people have very subtle symptoms that have developed gradually and gone unnoticed.

What causes dysphagia?

Dysphagia is a symptom, not a diagnosis in itself - it's always caused by something else. Common causes include:

• Neurological conditions such as stroke, Parkinson's disease, multiple sclerosis, or motor neurone disease
• Head and neck cancer or its treatment (surgery, radiotherapy, chemotherapy)
• Structural changes in the throat or oesophagus
• Dementia
• Ageing - swallowing function naturally changes as we get older
• Other medical conditions affecting muscle strength or coordination

Why does it matter?

Dysphagia isn't just uncomfortable - it carries real risks. The most serious is aspiration, where food or liquid enters the airway rather than the oesophagus. This can lead to aspiration pneumonia, which is a significant cause of hospitalisation and death in people with neurological conditions.

Even without aspiration, dysphagia can lead to malnutrition, dehydration, significant weight loss, and a dramatically reduced quality of life. Many people begin avoiding meals or eating in company, leading to social isolation.

When to seek help

If you or someone you care for is showing any of the signs above, it's worth getting a proper assessment - even if the symptoms seem mild. Dysphagia tends to be easier to manage when caught early, and there are effective strategies and therapies that can make a real difference.
