Hello, Thank you for your query. A Carotid doppler is the ultrasound of the arteries that supply the brain. Your report indicates that there is low grade blockage of the right internal carotid artery (40%) and the carotid bulb shows deposits (usually fatty deposits). This means that you are at risk for stroke (compromised circulation to the brain). Would you please clarify a few things for me? - how old are you? -what is your height and weight? -do you have any medical issues (high cholesterol, diabetes, hypertension etc) or take any medications? -any family history of heart disease, hypertension, diabetes, high cholesterol? -do you have chest pain or breathing difficulty? I recommend : - a physician and cardiologist consult -blood tests (complete blood count, TSH, lipid profile, blood glucose panel, kidney and liver function tests) -urine analysis -electrocardiogram and echocardiogram -a treadmill test if possible Based on the clinical findings and above test results, a treatment plan will be formulated. Medications usually include blood thinners, lipid lowering agents. Tight glycemic and blood pressure control with close monitoring of cardiac and renal status is required. Suggestions : - a regular exercise plan (after obtaining fitness from your doctor) -weight-loss if overweight -balanced nutritious diet with food Hydration (if not contraindicated by your doctor) *avoid refined grains and processed foods *include whole grains, fresh whole fruits and vegetables *limit oil intake to half a liter per month *avoid fried foods and junk food. Minimize salt intake. If you feel any breathing difficulty, giddiness, chest pain /discomfort, unexplained sweating, weakness of a leg/hand (even fingers or toes), slurred speech, vacant feeling, please go to the ER. Even if it only for a few seconds (this could be the start to a major stroke). Hope this helps. Please let me know if there is anything else I can help you with. Wish you good health
