<s>[INST] I was told 2 years ago by a cardiologist that I hve a left bundle branch blockage.  I am on blood pressue meds, that have been adjusted.  Now I am experiencing some dizziness with slight nausea.  I am trying to get back in to see the cardiologists.  Is that the correct Dr I need to see? [/INST] Hello,   Bundle branch don't need any treatment at this moment. It's because of hypertensive effects on the heart, you need to control your bp and frequently monitor. It's a right decision to visit doctor.    Regarding your nausea, dizziness you should check your blood pressure and pulse rate.Is it too high or low. Also, it can also be caused by gastritis and acidity problem. If you have bloating burping  vomiting upper abdominal pain etc it supports gastritis as cause.    You should have a healthy lifestyle like avoiding fatty, oily and high calorie diet. Have low salt diet and monitor blood pressure regularly thrice a day for one week then once or twice a week. If bp is persistently more than 140/90 mmhg, then bp med needs to be hiked up. Regular exercises like brisk walking, jogging according your capacity atleast 30 min a day and 5 days a week. Lots of green leafy vegetables, fruits, fish once or twice a week, avoid meat. Avoid smoking and alcohol if any. There shouldn't abdominal fat deposition or obesity. Get your lipid profile and sugars tested once..Hope this helps you and get back if you have any doubts. </s>
