Could Hot Flashes And Weakness Be Related To Hypothyroidism?

I HAVE BEEN HAVING SYNCOPY FOR SEVERAL YEARS NOW AND IN THE LAST SIX MONTHS IT HAD BEEN OCCURING EVERYDAY. I WENT TO A NEURO AND I AM ON KEPPRA AND ANAPROX DAILY AND THE FAINTING, LIGHT HEADEDNESS HAVE GOTTEN A LITTLE BETTER BUT I STILL HAVE THE HOT FEELING, WEAKNESS BUT NOT TO THE POINT OF FAINTING. IT IS LIKE THE KEPPRA IS PREVENTING THE FINAL PART. MY QUESTION IS - COULD THIS ALL BE CONTRIBUTED TO HYPOTHYROIDISM? I ALSO HAVE MIGRAINES, ALOPECIA AREATA, KIDNEY STONES, ASTHMA, JOINT AND BONE PAIN, FATIGUE, BRAIN FOG, EXCEMA, ACNE, TWO MISCARRIAGES, BLURRY VISION, VERTIGO, RECURRING SINUS INFECTIONS, CANDIDA
