Hi
Welcome to the MedHelp forum!
With headaches and hot flashes and lightheadedness with a feeling of passing out, you could be having either polycystic ovarian disease or GERD with or without H pylori infection. These are the two conditions to be ruled out first. Other conditions to be strongly ruled out in your case (if you have other symptoms such as ringing in the ear) could be cervical spinal nerve compression, Meniere’s disease of the ear, wax in the ear, infection of the middle or inner ear, and benign intracranial hypertension. Hence it is important to consult an ENT specialist and a neurologist too. At times back and neck problems may persist for years before they really start giving trouble. Chances of TMJ too should be looked into. Other causes are anemia, hypoglycemia or low sugar (maybe ruled out as you keep a check on blood sugar) and some endocrine problems, such as an underactive thyroid (called hypothyroidism), overactive thyroid (called hyperthyroidism), adrenal insufficiency (called Addison's disease), and in some cases, diabetes, may lead to hypotension and hence lightheadedness and an off balance feeling. It is really difficult to comment on the net. I suggest you consult your PCP to run the basic investigations and get an insight into what could be the cause. Depending on clinical examination and tests, your PCP can refer you to the appropriate specialist. Hope this helps. Please feel free to ask anything else you may want to know. Take care!
The same thing happened to me a couple of years ago and I took the advice of my dr and went for a sleep study. It turned out that I had sleep apnea and I was tested from 10pm until 1am in which time I stopped breathing over 100 times. My dr said that no matter how much sleep I was getting, I never really got into any kind of sleep that did my body any good.I was so sleep deprived that I would have major dizzy spells and it also caused my hormone level to get off thus causing hot flashes. You might just check it out, you never know. The first night that I slept with my CPAP machine, I felt like a new person and I do not miss a night with it. If I go away from home for one night, my machine goes to...good luck, hope you feel better soon!!!
i think your blood pressure got low that why you are having hot flashes and all that, you need to hydrate your self and eat a good healthy food, but if concerned see the doctor. Good luck.
