My grandma does not smoke or drink or do any sort for sudden reason for hypertension. She does exercise, yoga and eat healthy balanced diet. But out of nowhere, she vomits and cannot eat anything for almost 3 days and we put her in ICU due to severe weakness. She cannot eat, walk and her response while talking is slow. We have already performed major tests and ultrasounds like ECG, CRT scan etc resulting to no such internal stomach problem or any significant notice in results. A little bit of rise in sugar, that's it. I am very much worried and want to know other possibilities that the doctors are missing to find and how to lower the blood pressure. Please any help would be much much appreciated. God Bless!!
