<s>[INST] I m asking this question for my mother. She is 67 yr s old she weighs about 169 lbs. Her BP this morning was 146/110 but when she takes her BP medication the upper # of her BP comes down slightly but her lower # goes down to between 50 - 30 s. What s going on? [/INST] Hello, This occurs due to age related changes like hardening of blood vessels. There is no focus and worry about lower BP, it's not that important. The blood pressure should be less than 140/90 MMH. Even the lower BP goes below 50 it's not a matter of worry, but upper one should be controlled.  She 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. Regular exercises like brisk walking, jogging according your capacity at least 30 min a day and 5 days a week. Lots of green leafy vegetables, fruits, fish once or twice a week, avoid meat. There shouldn't abdominal fat deposition or obesity. Get your lipid profile and sugars tested once. </s>
