An Uncommon Case of Weight Loss in a Nonagenarian.

Weight loss in older adults can be due to multiple causes. A systematic approach is required to pinpoint the etiology. Dysphagia is an important symptom associated with weight loss. In the absence of anatomical abnormalities, functional swallowing disorders such as achalasia can be mistaken for an aging esophagus or oropharynx. The incidence of achalasia in older adults is rare, with most cases presenting between 30 to 60 years of age. Here, we present an uncommon case of achalasia in a 93-year-old Chinese woman. A barium swallow and high-resolution manometry confirmed the diagnosis of achalasia. Botulinum toxin injection was administered. She did well, achieving weight gain and resolution of her symptoms. In conclusion, early recognition and appropriate management of uncommon causes of weight loss can greatly improve the quality of life of older adults.
