Hello! Welcome on HCM! Regarding your concern, I would explain that these high blood pressure values could be related to different causes: 1- thyroid hormone imbalance. As you are taking levothyroxine, it would be necessary check your thyroid hormone levels to regulate the dose of levothyroxine. 2- Other secondary causes of high blood pressure should be excluded. That is why I would recommend performing some other blood tests : - complete blood count for anemia - liver and kidney function tests for possible dysfunction - fasting glucose for diabetes - blood electrolytes for possible imbalance - inflammation tests (PCR, sedimentation rate). 3- If all the above mentioned tests result normal, primary hypertension should be taken into consideration. In such case, you should discuss with your doctor on the possibility of starting anti-hypertensive therapy. Meanwhile, I would recommend some tips to help maintain a normal blood pressure: - reduce salt and caffeine intake - perform a lot of physical activity (walking, aerobics, recreational sports) - try to lose some weight if your are overweight. Hope you will find this answer helpful! Kind regards, Dr. Iliri
