Dysphagia

Overview


What is Dysphagia?

Dysphagia is a swallowing disorder. Patients with a swallowing disorder may face the risk of developing pneumonia (chest infection), whereby food/fluid enter the lungs.


In general, there are 3 swallowing stages:

  • In the Mouth (Oral Stage)

    Food is chewed into a bolus (ball) and pushed to the back of the mouth by the tongue to trigger a swallow.



  • In the Throat (Pharyngeal Stage)

    The throat is separated into 2 openings at the lower end: the trachea/airway (below the voice box) and the oesophagus/foodpipe. When the food is pushed to enter the foodpipe, a flap-like structure called the epiglottis, covers the airway to prevent any leakage into the lungs.



  • In the Foodpipe (Oesophageal Stage)

    At this stage of swallowing, the airway is sealed and the sphincter (valve) at the top of the foodpipe opens up to allow the food/fluid to slide down with muscular action.

    Subsequently, the sphincter at the end of the foodpipe opens up to allow the bolus to enter the stomach.



Causes

  • After-effects of a surgery that involves the removal of lumps or tumours in the mouth, throat or foodpipe
  • Side effects from chemotherapy or radiotherapy
  • Neurological issues such as stroke, head injury, Parkinson's, etc
  • Respiratory (breathing) problems
  • Multiple medical conditions that weaken the swallowing system
  • Ageing
Signs & Symptoms
  • Difficulty in swallowing saliva or drooling
  • Presence of residue of food/fluid in the mouth after swallowing
  • Chewing/sucking difficulties
  • Wet voice or throat noises after swallowing
  • Throat-clearing, choking or coughing during or after swallowing
  • Shortness of breath after swallowing
  • Recurrent chest infection or fever
  • Unintended/ unexplained weight loss

Detection & Treatment

Diagnosis

Your doctor will review your symptoms and may refer you to a Speech Therapist for an assessment of your swallowing status. The therapist will then do a physical examination and assess your swallowing when you eat or drink.


Further instrumental examination may be required e.g. doing a video X-ray (Videofluoroscopy) or a scope (Flexible Endoscopic Examination of Swallowing) when deemed necessary.

Care Management

How is Dysphagia Managed?

Patients with dysphagia are co-managed by the doctor and the speech therapist. Management of your swallowing condition may include:

  • Modification to the type, texture and consistencies of your food or fluid
  • Oral-motor exercises
  • Specific swallowing strategies for safe swallowing
  • Use of instrumental devices e.g. surface electro-myographic feedback, a nose scope, special cutlery to assess and/or teach therapy techniques

Tips to Improve Your Swallowing

  • Keep upright when eating/drinking
  • Take small sips when drinking. Using a straw to suck may be difficult to control the rate and amount of fluid intake, causing you to cough
  • Take small, bite-sized mouthfuls when eating
  • Do not drink more water to flush food down when you cough while eating/ drinking. Cough out any food/ fluid first and let your breathing settle before you continue to eat or drink
  • Take soft foods such as porridge, bean curd and oats
  • Chop up fibrous/ hard foods e.g. vegetables, fruits and meat
  • Separate the solids from the liquids e.g. do not put noodles in a spoon of soup to eat. Try to swallow the noodles completely before drinking the soup
  • Use thickening agents to hold food together e.g. corn flour, sauces, gravy or fluid thickener to allow easier swallowing
  • Avoid talking with food in your mouth. Cut down distractions during eating/drinking

If your condition persists or worsens, please consult your doctor or speech therapist.
