Sir, I am 42 yr old female, 5.3 height, and a house wife. I have giddiness since 4 months. my audiogram report is normal. thyroid is also normal. no sugar, but cholestrol is 230, my heart beats are also missing in between. so did echo test and ECG too. both are normal. so I want to know what is the reason for giddiness? at the time of echo my bp was little bit higher 160/90. but later it was 120/80 for one week...
