Metabolic Changes Associated With Weight Gain After Treatment of Achalasia

This goal of the study is to assess the effect of weight gain in patients with achalasia after they are treated. The main question to be answered is if weight gain after achalasia treatment is associated with worsening metabolic status. Patients will be compared between their baseline status at the time of treatment and 1 year after treatment. Participants will have metabolic tests performed at these 2 times including blood tests.
