What can a blood test diagnose?

Question

So I almost fainted this morning in the bathroom. My legs, arms, hands, and feet were all tingly. I was extremely pale including my lips which were white. I was also sweating a lot. My vision was all spotty too and I could hardly see. I had to put my head inbetween my legs for about 5 minutes, drink water, and eat chocolate. I then felt better after this. This has happened to me before in the past. If I get a blood test could it tell me what's wrong with me? What could it possibly be?

You need to go to the doctor for a little checkup.   A blood test could tell you a lot.  For instance, your hemoglobin could be low, because that can cause symptoms like you have had.  They will check other things in your blood, too.

Are you eating properly and drinking enough water?   A lot of people don't drink enough water and they get dehydrated, and that can cause problems.

So don't panic---just go see a doctor and be honest about everything.
