Difficulty swallowing

What it is

Swallowing is a fast, precisely coordinated sequence involving over thirty muscle pairs. The suprahyoid muscles lift the voice box, which closes the airway and opens the passage to the oesophagus. When they weaken, the sequence slows, the airway closes less completely, and material can enter the airway instead.

Age-related weakening of these muscles - presbyphagia - is a form of sarcopenia in muscles that nobody considers training. It matters because aspiration pneumonia is one of the leading causes of death in older adults, and swallowing strength is trainable in exactly the way limb strength is.

What it feels like

• Food sticking in the throat, or needing several swallows to clear a mouthful
• Coughing or throat clearing during or just after eating or drinking
• A wet or gurgly voice after swallowing
• Meals taking much longer, and avoiding certain foods
• Weight loss, and increasing anxiety about eating with other people

What causes it

Most people have more than one of these at once, and they feed each other. Read the list looking for the two or three that sound like your week rather than for the one true answer — the ones that describe you are the ones worth acting on.

Age-related weakening of the swallowing muscles

The suprahyoid and pharyngeal muscles lose strength and speed with age. The swallow becomes slower and less forceful, with less airway protection - a form of sarcopenia in muscles that are never trained.

Reduced tongue strength

The tongue drives the bolus backward with considerable force. Tongue pressure declines with age and correlates with swallowing efficiency, and it is directly trainable.

Stroke

The commonest medical cause. Swallowing difficulty affects a large proportion of people after stroke, and it is one of the strongest predictors of pneumonia and poor outcome.

Parkinson's disease and other neurological conditions

Slowed, reduced-amplitude movement affects swallowing as it affects everything else. Motor neurone disease, multiple sclerosis and dementia all impair swallowing.

Head and neck cancer treatment

Surgery and radiotherapy produce fibrosis and muscle damage that can severely and permanently affect swallowing, sometimes appearing years after treatment.

Reflux and oesophageal narrowing

Long-standing reflux can produce a stricture, and food sticking low down at the breastbone is a different problem from difficulty initiating the swallow.

Poor dentition and dry mouth

Inadequate chewing and reduced saliva - very common with medication in older adults - both make the swallow harder before it has started.

Sarcopenia elsewhere

General muscle loss and swallowing muscle loss travel together. Someone frail enough to have difficulty standing often has difficulty swallowing too, and the two respond to the same principle.

Prolonged tube feeding or nil by mouth

Swallowing muscles waste with disuse like any others. Long periods without swallowing make returning to oral intake harder.

Cancer of the oesophagus - the exclusion

Progressive difficulty, first with solids then with liquids, with weight loss, is a red flag needing urgent investigation rather than exercises.

Who tends to get it

• Older adults, particularly those who are frail or losing weight
• Anyone who has had a stroke
• People with Parkinson's disease or another neurological condition
• Anyone treated for head and neck cancer
• People with poor dentition, dry mouth or on multiple medications

What makes it worse, and what settles it

No ready-made routine for this one yet

249 of the 267 problems here have a routine already built, and this is not one of them — usually because the work that helps is covered by a general routine rather than needing its own. What actually helps above names the muscles and the work involved, which is enough to put it together yourself.

Get it checked if…

Coughing or choking on food or drink, recurrent chest infections, or unexplained weight loss needs a swallowing assessment BEFORE any exercise - aspiration is dangerous

And whatever the body part: chest pain or unusual breathlessness on exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or one calf that is swollen, warm and painful. Any of those, stop and get assessed.

How it usually goes

Swallowing muscle training improves function measurably, with results over eight to twelve weeks - the same timescale as any other strength training, because that is what it is. A speech and language therapy assessment is the right starting point and it is widely available. Progressive difficulty, particularly moving from solids to liquids, or accompanied by weight loss, needs urgent investigation before any exercise programme. Repeated chest infections in someone with swallowing difficulty is a serious sign.
