Dysphagia

—

In one line

·Trouble moving food or liquid from the mouth, through the throat, and down the esophagus (the swallowing tube) to the stomach.

Normal physiology

·Swallowing moves food from your mouth, through your throat, and down a long tube called the esophagus into your stomach — all while protecting your airway so nothing goes into your lungs. Every weird symptom makes sense once you see what this normal system is supposed to do.

What goes wrong

·Swallowing can break in two big places: in the throat — called oropharyngeal trouble swallowing (dysphagia) — or in the tube below — called esophageal trouble swallowing. Throat problems usually come from weak or uncoordinated muscles and nerves, like after a stroke, with Parkinson's disease, ALS (Lou Gehrig's disease), myasthenia gravis (a disease where muscles tire out), or after surgery or radiation for head and neck cancer. Tube problems usually come from something blocking or narrowing the path, like a tight scar called a stricture from acid reflux, a ring of extra tissue called a Schatzki ring, a tumor, or a motility disorder where the squeezing waves do not work — such as achalasia or scleroderma esophagus.

Hallmark signs

·Food sticks or feels slow going down
·Coughing or choking when swallowing
·Food or liquid comes back up into the nose or mouth (regurgitation)
·Voice sounds wet or gurgly after swallowing
·Pain when swallowing (called painful swallowing (odynophagia))
·Unintended weight loss
·Repeated lung infections (aspiration pneumonia)
·Drooling or unable to control saliva

Red flags · escalate now

·Sudden complete inability to swallow solids or liquids (may signal a full blockage in the esophagus or an acute stroke cutting off swallowing signals)
·Severe chest pain or vomiting blood with swallowing trouble (may mean a tear in the esophageal wall called a perforation, or bleeding from an ulcer or tumor)
·Fast, unexplained weight loss or night sweats (may signal esophageal cancer or another serious illness)
·New trouble swallowing after age 50 (higher risk of cancer or stricture needing urgent evaluation)
·Repeated lung infections or pneumonia from aspiration (shows food is entering the lungs and needs immediate swallowing assessment to prevent respiratory failure)

—

Workup

·Bedside swallow screen (water swallow test or 3-ounce water challenge)
·Modified barium swallow study (also called videofluoroscopic swallow study or VFSS)
·Fiberoptic endoscopic evaluation of swallowing (FEES)
·Chest X-ray
·Upper endoscopy (EGD — a camera down the throat into the stomach)
·Esophageal manometry (pressure sensor test of the food pipe)
·Brain MRI or CT (if sudden onset or one-sided weakness)
·Serum creatine kinase (CK) and aldolase (if muscle disease suspected)

—

Treatment

·Speech-language pathologist (SLP) swallow evaluation and therapy
·Treat the root cause — stroke rehab and antiplatelet drugs (aspirin or clopidogrel), Parkinson disease medications (levodopa/carbidopa), myasthenia gravis immunotherapy (pyridostigmine, steroids, or IVIG — intravenous antibodies that calm the immune attack), esophageal stricture dilation, achalasia pneumatic dilation or Heller myotomy, head/neck cancer resection or radiation
·Diet modification — thickened liquids (nectar, honey, or pudding thickness) and texture-modified solids (pureed, minced, or soft foods)
·Feeding tube (nasogastric tube for short-term or PEG tube — percutaneous endoscopic gastrostomy, a tube through the belly wall into the stomach — for long-term) if oral intake is not safe
·Aspiration precautions — keep head of bed elevated at least 30 to 45 degrees during and for 30 minutes after eating or tube feeds, never feed someone lying flat, provide frequent mouth care
·Antibiotic therapy for aspiration pneumonia (usually ampicillin-sulbactam, piperacillin-tazobactam, or a respiratory fluoroquinolone such as levofloxacin or moxifloxacin plus metronidazole if anaerobic coverage is needed)
·Botulinum toxin injection into the upper esophageal sphincter or cricopharyngeus muscle (for cricopharyngeal dysfunction) or pneumatic dilation/Heller myotomy (for achalasia)

NCLEX trap

·Thin liquids are the HARDEST thing to swallow safely when someone has trouble swallowing. They move fast — they can slip into the trachea (the airway to the lungs) before the throat muscles have time to close and protect it. Thickened liquids (like nectar-thick or honey-thick) move slower, so the pharynx (the throat) has a few extra seconds to squeeze shut and keep the liquid out of the lungs. Always thicken liquids first when trouble swallowing (dysphagia) (trouble swallowing) is present. This is standard teaching from the American Speech-Language-Hearing Association (ASHA) and stroke guidelines.
·Speech therapists (SLP), not physical therapists (PT), are the experts who check swallowing. SLP watches how the mouth and throat move, does a bedside swallow test, and orders special X-rays (modified barium swallow study, or videofluoroscopy) or a camera test (FEES — fiberoptic endoscopic evaluation of swallowing, a tiny scope down the nose) if needed. PT works on arms, legs, balance, and walking — not swallowing. Wrong specialist means wrong treatment, and that leads to food going into the lungs (aspiration) and pneumonia.
·Sitting upright (90 degrees, like in a chair) or at least semi-upright (45 to 60 degrees) is the ONLY safe way to eat when someone has swallowing trouble. Gravity helps food and liquid go DOWN into the esophagus (the food tube) and stomach, not backwards into the trachea (the airway). Lying flat or leaning back makes food roll the wrong way — straight toward the lungs. Position is not just comfort — it is protection. Flat equals aspiration. Keep the patient upright during the meal AND for at least 30 minutes after eating, so gravity keeps working and nothing sneaks back up.
·New fever PLUS new cough PLUS recent swallowing trouble means aspiration pneumonia (infection in the lungs from food or liquid that went down the wrong pipe) until proven otherwise. This is a medical emergency. Get a chest X-ray (usually shows a white patch in the right lower lobe, because of how the airways branch) and start antibiotics right away — typically ampicillin-sulbactam (Unasyn) or a respiratory fluoroquinolone like levofloxacin or moxifloxacin, to cover mouth bacteria (like anaerobes and Streptococcus) that get into the lungs. Aspiration pneumonia can kill, especially in older adults or people who are already weak. Do NOT wait.
·The cough IS the body trying to protect the lungs from food or liquid going the wrong way. If you stop the cough with medicine, you hide the problem and make aspiration WORSE because now the person cannot clear the airway. Fix the swallowing — thicken liquids, change the diet, sit the person upright, get SLP involved — and the cough will stop on its own. Treat the cause, not the symptom. Sedatives also slow down the already weak throat reflexes and make aspiration even more likely. Never suppress a protective cough in someone with trouble swallowing (dysphagia).
