Dysphagia ie difficulty swallowing can be caused by various conditions . Some of them are
1) Esopahgeal cancer: Cancer of the esophagus which leads to obstruction and consecutively dysphagia
2) Achalasia: ie movement disorder of the esophagus
3) Diffuse esophageal spasms: ie the muscle layer of the esophagus contracts abnormally
4) other conditions like esophageal strictures, scleroderma all of which either obstruct and narrow the lumen of the esophagus or lead to muscle contraction problems.
I Hope this helps.
