What Causes Dizziness And Low Bp?

last week I went to my MD for some cortisone shots and you know they always check your vitals. When BP was taken, the first reading was 94/56 and the second time, approximately 15 minutes later was around 98/58. Since March, I've lost 152 pounds due to a gastric Bypass. I'm an cardio junke and weight train 5 days a week. I'm now down to 178. Once in awhile when I get up from a seated position a get a little dizzy/light headed. Do I have a major issue here?Thanks Jeff

Thanks for your question on Healthcare Magic.
I can understand your concern.
Your symptom of dizziness especially on getting up is due to hypotension only.
Blood pressure values of 94/56mmhg, 98/58 mmhg etc are suggestive of hypotension.
Since you had gastric bypass and lost 152 pounds, possibility of nutritional and electrolytes deficiency is more.
Gastric bypass surgery causes poor absorption of nutrients and electrolytes.
All these are normal to maintain blood pressure.
So consult doctor and get done serum electrolytes (sodium, potassium, chloride).
If deficiency then you will need supplements.
Drink plenty of fluids including oral rehydration solution (ORS) and fruit juices.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
