Swallowing problems may be due to infections, such as:
Cytomegalovirus
Gum disease (
gingivitis)
Herpes simplex virus
Human
immunodeficiency virus (HIV)
Pharyngitis (
sore throat)
Thrush
Swallowing problems may be due to a problem with the esophagus, such as:
Achalasia
Esophageal spasms
Gastroesophageal reflux disease
Inflammation of the esophagus
Nutcracker esophagus
Ulcer in the esophagus, especially due to the antibiotic doxycycline
Other causes of swallowing problems include:
Mouth or throat ulcers
Something stuck in the throat (for example, fish or chicken bones)
Tooth infection or abscess
The doctor will try to determine where the problem lies - which part of the swallowing process is causing the difficulty.
The patient will be asked about symptoms, how long they have been present, whether the problem is with liquids, solids, or both.
Additionally, the patient will be weighed and asked if their current weight is about right.
Swallow study - a swallow study is usually administered by a speech therapist. They test different consistencies of food and liquid to see which cause difficulty. They may also do a video swallow test to see where the problem is.
Barium swallow test - the patient swallows a barium-containing liquid. Barium shows up in X-rays and helps the doctor identify what is happening in the esophagus in more detail, especially muscular activity.
Endoscopy - a doctor uses a camera to look down into the esophagus. They may take a biopsy if they find something concerning for cancer.
Manometry - this study measures the pressure changes produced by contractions of the muscular portions of the esophagus. This may be used when an endoscopy yields normal results.
