Understanding Esophageal Dysmotility
Esophageal dysmotility is a condition that affects the esophagus, a long fibromuscular tube connecting the throat and the stomach. Its primary function is to facilitate swallowing and prevent gastric reflux. However, in individuals with CREST syndrome, the smooth muscle in the gastrointestinal tract can undergo atrophy, resulting in impaired esophageal motility.
One of the main symptoms of esophageal dysmotility is chest pain. This discomfort may be accompanied by coughing or a sensation of food getting stuck in the esophagus. To overcome this issue, many individuals with esophageal dysmotility find it necessary to drink liquids while eating to ensure that solid food can pass through to the stomach properly.
However, this compensatory measure can lead to additional challenges. Drinking liquids during meals can increase the likelihood of acid reflux, heartburn, and inflammation. As a result, individuals with esophageal dysmotility often experience these symptoms more frequently.
Sclerodactyly: A Prominent Symptom of CREST Syndrome
Sclerodactyly is a notable symptom associated with CREST syndrome, characterized by the thickening of the skin on the fingers. Typically, this condition affects the tips and middle areas of the fingers. In its early stages, the skin may appear inflamed or show signs of fluid retention. However, as the condition progresses, collagen deposits begin to accumulate, resulting in the tightening and hardening of the skin.
Furthermore, it is estimated that between 30% and 50% of individuals with CREST syndrome also develop ischemic ulcers in their fingers, adding to the complexity of the condition.
