Understanding Dysphagia
What is dysphagia? Dysphagia is a term for difficulties with chewing or swallowing food and fluids. Dysphagia is common after brain injury. For some people it improves during early recovery, though for others it can last months or become a long-term issue. You can find out more by visiting Headway’s Information Library.
How can brain injury cause dysphagia? Swallowing is a complex process. It involves multiple stages controlled by areas of the brain, nerves and many muscles in the head, face, neck, mouth, and throat. Damage to any part of this system can disrupt swallowing.
There are two main types of dysphagia after brain injury:
• Oral dysphagia — difficulty chewing or controlling food/drink in the mouth: problems sealing the lips, moving the tongue, forming a bolus, or getting it safely to the back of the mouth.
• Pharyngeal dysphagia — difficulty in the act of swallowing. Food or drink may go “down the wrong way,” entering the airway instead of the gullet, leading to aspiration.
Other brain injury effects such as reduced sense of taste or smell, impaired saliva production, reduced awareness of eating, as well as cognitive and behavioural changes may worsen dysphagia.
Beyond physical health, dysphagia can significantly impact quality of life — meals can become stressful or unpleasant, social eating difficult, and people may avoid eating all together; this can affect mood and self-confidence.
Treatment and management There’s no one-size-fits-all “cure” — treatment depends on the type and severity of dysphagia. The main aims are to restore safe swallowing, reduce risk of aspiration or lung infection, and maintain adequate nutrition and hydration. Possible approaches include:
• Swallowing therapy — exercises and strategies from a speech and language therapist to strengthen muscles, re-train coordination of swallow, or stimulate nerves involved in chewing/swallowing.
• Diet modifications — changing food textures (pureed foods, thickened liquids), or prescribing nutritional supplements if swallowing solids or pills is difficult.
• Enteral feeding (feeding tubes) — when oral intake isn’t safe or sufficient. Short-term options include a nasogastric (NG) tube; long-term solutions might use a Percutaneous Endoscopic Gastrostomy (PEG) or Radiologically Inserted Gastrostomy (RIG) tube.
Feeding tubes are sometimes temporary and can be removed if swallowing improves enough for safe oral intake.
Practical strategies and coping tips On top of therapy and medical interventions, the following everyday strategies can help:
• Stay upright during and after meals, ideally for 30-60 minutes post-eating — helps swallowing and digestion.
• Make food more appetising (sight, smell, taste) to encourage saliva production and stimulate appetite — particularly useful when taste or smell are impaired.
• Use specialist eating equipment when needed — e.g., one-way drinking straws, weighted cups — but always after a proper swallowing assessment.
• Maintain good oral hygiene before and after meals to reduce risk of aspiration of bacteria or debris.
• Eat in a calm, low-distraction environment; take time to eat slowly and chew thoroughly.
• When going out (e.g. to restaurants), plan ahead — many places will accommodate special dietary needs if notified.
Also: when medication is prescribed, it’s vital to discuss dysphagia with a doctor — some tablets are hard to swallow, and should never be crushed or altered without professional advice.
Why awareness and early action matters Because swallowing and chewing involve so many parts of the brain and body, dysphagia after brain injury can take many forms — and severity can vary widely between individuals. If ignored or left unmanaged, dysphagia can lead to serious health risks — malnutrition, dehydration, aspiration pneumonia — and dramatically reduce quality of life.That makes early diagnosis, professional assessment, and tailored management essential. Sometimes swallowing improves naturally during recovery; other times long-term support is needed. Either way — eating and drinking safely should be a priority.
