R-CPD and death
While not inherently fatal, retrograde cricopharyngeus dysfunction (R-CPD) can lead to potentially life-threatening complications if left undertreated. The impaired ability to swallow food and liquids safely can set the stage for malnutrition, aspiration, and choking episodes that may ultimately prove fatal.
The most imminent risk of R-CPD is pulmonary aspiration due to food or saliva entering the airway. Inhalation of foreign material into the lungs can cause aspiration pneumonia, a serious infection. Inflammation and compromised breathing can be severe enough to require hospitalization in some cases.
Over time, the malnutrition and dehydration stemming from disordered swallowing also takes a toll on the body. Essential nutrients are required to maintain organ function and fight infection. Deficits make the body vulnerable to heart failure, kidney dysfunction, and multiple other deficiencies.
The stress of struggling to swallow can also provoke anxiety and depression in some individuals. Extreme weight loss from eating difficulties may affect personal identity. Combined mental health impacts have been known to lead to suicidal thoughts in rare cases.
Statistically, the most common immediate causes of death for R-CPD patients are pneumonia and respiratory failure. However, later fatalities related to the chronic effects of malnutrition and metabolic abnormalities are also reported. Advanced age and other medical issues may influence mortality risk.
Thankfully, early diagnosis and proper management greatly improve the prognosis for those with R-CPD. Following an appropriate treatment plan and monitoring for signs of aspiration are key to reducing complications. With proper care, most R-CPD cases do not result in severe health outcomes. But untreated or undiagnosed dysphagia does carry potentially grave risks that should not be overlooked.
