<bot>: HIT hanks for posting your query. There are many causes for Dizziness, from simple and easily treatable causes to serious causes. Simple causes are :1. Abnormalities in BP: Both high and low BP can cause dizziness. 2. Abnormalities in Blood sugars: Both high and low Blood sugars can cause dizziness.3. Abnormalities in blood sodium levels. 4. Low Hemoglobin (Anemia)5. Inner Ear problems. Some serious problems are :1. Heart Problems2: Brain problem In your case, Heart problems is one possible cause of Dizziness. So kindly get your BP checked and get a treadmill test done which shall reveal any abnormalities in the heart. If it comes normal then get the following things done.  Get your Hemoglobin, Serum Sodium levels, ENT and 2D Echo checked and if they are normal get an MRI Brain done. Revert to me any time you want. Hope you find this information useful. Any clarification feel free to ask
