<s>[INST] Periodically my wife gets somewhat nauseated and has the feeling that she is hot, especially her face.  The fever thermometer says normal--blood pressure is variable and too high. She is 83 years old, 5'4", 160 lbs.  Had a stroke January 2005. Nearly fully recoverred. [/INST] Hello!Thank you for asking on HCM!Regarding your concern, I would explain that her symptoms could be related to high  blood pressure. I recommend consulting with her attending physician for a physical exam and some lab blood tests (complete blood count, thyroid hormone levels, kidney and liver function tests, fasting glucose, blood electrolytes), in order to exclude possible secondary causes of high blood pressure. You should discuss with her doctor on the possibility of optimizing her antihypertensive therapy in order to have a better control of her blood pressure. I would also recommend some lifestyle modifications: - reduce salt and caffeine intake- perform a lot of physical activity (walking, aerobics)- try to lose some weight if she is overweight. Hope to have been helpful!Kind regards, Dr. Iliri </s>
