Final answer:
The patient's described symptoms and habbits are indicative of GERD; thus, the first step in management should be lifestyle modifications and smoking cessation before considering pharmacological interventions.
Step-by-step explanation:
The patient's symptoms, including burning, retrosternal pain after eating, lying down, or bending over, and morning hoarseness, suggest a likely diagnosis of gastroesophageal reflux disease (GERD). Considering the benign nature of the examination, the most appropriate initial step in management would likely involve non-pharmacological lifestyle modification and smoking cessation if applicable. Such modifications may include eating smaller meals, avoiding foods that trigger reflux, elevating the head of the bed, and not lying down immediately after eating. Pharmacologic intervention could be considered if lifestyle modifications are insufficient.
