Thanks for contacting HCM with your health concern and following is symptomatic approach: 1. mibets SR: (propranolol) is used to treat high blood pressure, arrhythmis, angina, and migraine headache anf should be taken constantly with or without food and under no circumstances you should think of stopping it suddenly or changing to another alternative without first contacting your attending physician. 2. although some people have reported bloating while on propranolol but they also have associated medical conditions like high blood pressure, depression, gastro esophageal reflux disease, stress/anxiety, and to reduce the long term side effect of bloating & fluid retention it is combined with the diuretic. 3. check with a Cardiologist first for high blood pressure since medicines fo migraine & high blood pressure interact with each other.
