<s>[INST] I have a brother who is 42 years old. He is experiencing occasional high heart beat and stomach Acid flux. He thinks is related to his heart but I think is due to anxiety and/or depression. He wants to see a Cardiologist. What do you recommend? Thank you [/INST] Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, he is mostly having stress and anxiety related HERD (gastroesophageal reflux disease). But better to get done ECG to rule out heart diseases. If ECG is normal then no need to worry about heart diseases. Stress, anxiety and depression cause laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause the symptoms of gastritis, chest pain, chest tightness, burping etc. So control of anxiety and depression are must in his case and hence better to consult psychiatrist and get done counselling sessions. Try to identify stressor in his life and start working on its solution. He may need anxiolytic and anti-depressant Chat Doctor.  For stomach problem, give him antacid like proton pump inhibitors. Don't worry, he will be alright. Hope I have solved your query. I will be happy to help you further. Wishing good health to your brother. Thanks. </s>
