What Causes Severe Dizziness?

Hi, For the last two days I have been suffering terrible dizzy spells. The first time was yesterday when I was getting gas for my truck and almost passed out. I became extremely shaky and couldn t walk straight. I went home and had my roommate drive me to the ER. There they did a blood, and urine test while checking my blood sugar and blood pressure. When I saw the dr he said that I was dehydrated due to having a very concentrated urine sample. Today I have been drinking plenty of water and have also eaten food. I however am still getting terrible dizzy spells and it seems like when I have to do a bowel movement these spells come on. I have to work in a couple days and cannot afford to loose my job, please help me understand what s going on. Thank you

Hello!

Thank you for asking on HCM!

I read your question carefully and understand your concern.

Your symptoms may be related to an inner ear problem. Are your dizzy spells triggered by the head movements?

As you refer all your lab tests have resulted normal.

I would recommend to consult with the ENT specialist and perform an electronystagmography and labyrinthine test to exclude the inner ear as a possible cause of this symptomatology.

Another issue is your blood pressure. An orthostatic hypotension would cause lightheadedness and dizzy spells, exacerbated by standing up. A head up tilt test would be useful to rule out this possible disorder.

Meanwhile I recommend betahistine twice daily for some days.

Hope to have been of help!

Best regards,
Dr. Iliri
