Hi, I, Been Having Thyroid, Problems For A Long Time,

Hi, I, been having thyroid, problems for a long time, can it make me as a patient dizzy, or depress a lot, and make u, have hair loss. I'm also on blood pressure medicine. I, walk ever day and eat less and drink lots of water to help me to maintain hunger. Im, beginning to have hot flashes at night, is that cause from the disease?
