This free online healthcare course covers the causes, symptoms and treatment of dysphagia, a swallowing disorder.

Dysphagia, a swallowing disorder, involves abnormal time or effort to move food from the mouth to the stomach. It can stem from throat obstructions or medical conditions affecting the neurological system or muscles. Treatment approaches vary based on the underlying cause. This course will teach you about dysphagia, covering its causes, symptoms, diagnosis, and control methods, emphasizing the importance of good oral health.

We'll distinguish between the incidence and prevalence of disorders. Dysphagia often brings phobias, impacting a patient's quality of life by making meals and social gatherings difficult. We’ll outline the medical and psychological consequences of dysphagia and identify relevant specialists. You'll study the anatomical and physiological structures involved in swallowing, including their functions and locations. The course also covers taste stimulation mechanisms, describing the role of saliva, temperature, and pressure receptors.

Finally, we'll examine dysphagia symptoms and aspiration pneumonia, caused by food entering airways. You'll learn about pseudobulbar palsy (impaired facial muscle control) and the role of evidence-based medicine in diagnosis and treatment. We’ll discuss the International Dysphagia Diet Standardisation Initiative (IDDSI), its framework, and implementation toolkits. We'll examine crucial oral healthcare procedures for dysphagia, including periodontal treatment and maintenance. Dysphagia, whether mild or severe, significantly affects quality of life and must be taken seriously.
