Would Dehydration Cause Sudden Drops Of Blood Pressure?

I recently lost 30 lbs and my blood pressure was consistently 120/70. Now that I weigh less, my blood pressure is consistently 100/62 with a normal heart rate of 78-86. Would dehydration cause sudden and short lived blood pressure drops? I have been getting bouts of dizziness and almost feint for about 20 second and it doesn't matter whether I am sitting or standing. I know you can get dizziness from getting up fast but that is not the case with mine. I also suffer from arrythmias on occassion where I feel dizzy and feinty and my heart rate jumps to over 200bps.

If your heart rate jumps to around 200 bpm, it is something abnormal for which you need to seek immediate attention.
I would suggest you meet a Physician or cardiologist so that the necessary test be done to rule out arrhythmias. Holter monitoring would be a good option to detect these abnormal beats.
