Thanks for your question on Health Care Magic. I can understand your situation and problem. By your history and description, possibility of GERD (gastroesophageal reflux disease) is more. Coffee contains caffeine. You are also having obesity. Caffeine and obesity cause laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause the squeezing feeling in chest. So better to avoid excessive coffee and loose weight. Avoid hot and spicy food, avoid large meals. Start proton pump inhibitors and prokinetic drugs to prevent reflux disease. Hope I have solved your query. Wish you good health. Thanks.
