Hi, Thanks for asking. Based on your clinical history and query, my opinion is as follows: 1. Low potassium can increase blood pressure, however, it is usually not the sole reason. You need to be on anti-hypertensives with consultation from your doctor. 2. Taking potassium tablets is risky. Cardiovascular effects, particularly arrhythmia are dangerous. 3. You can concentrate on improving potassium by improving diet by including items like banana, green leafy vegetables, potatoes, fish, yogurt, mushrooms, etc. Improving potassium will reduce risk of high blood pressure, stroke and cardiovascular disease. Hope it helps. Any further queries, happy to help again.
