I am thirsty often during the day, but it doesn't seem excessive to me until the evenings. After my evening meal, I do feel that my thirst is excessive. I do use salt in my food, but I don't think it is excessive. This excessive thirst in the evenings occurs no matter what I eat, or what activities I engage in. It has been ongoing every evening all winter.
I am otherwise healthy, but do have some osteoporosis in my hips, some migraine headaches, and after getting through the flu, I have an itchy rash on my back that is puzzling. I take supplements under my doctor's guidance such as calcium, vitamin D, tyrosine, DHEA, and recently added iron chelate gelcaps for my red blood count was a little low.
I am a post menopausal woman, age 56. I have not mentioned this to my doctor yet.
