Hi I am 17 years old and I am a female. Recently I found out I have low blood sugar. However, everytime i stand up I blackout and have to hold on to something (what happens is like when you rub your eyes really hard then let go and its all fuzzy etc). I was a bit overweight so i have been trying to lose weight. And not only does this happen when i stand up, i can randomly be standing/walking outside or inside and the same thing will take place. And lately i get tried very quick and everytime I do something and i go fast i get really weak after. I have no idea what this is.
Hi, You are 17 years, female, over weight.  It appears that you might be having hypothyroidism, or may be having hypo avitaminosis, anemia, or genetic over weight with cardiac involvement.  I usually prescribe to such patients iron substitutes, complex, and protein substitutes, and get the thyroid profile, ECG, and hemoglobin estimation etc. for confirmation.  So I advise you to consult a physician for treatment. Thank you.
