What Causes Nausea, Frequent Urination And Cold Feet When Suffering From Hoshimoto's Thyroiditis And Sarcoidosis?

For the last month and a half I have been feeling nauseous and early satiety after some meals and my hands and feet are cold all the time it seems. I also have had a few dizzy spells when standing up too quickly with nausea either from seated or lying position. I also have been needing to urinate several times before falling asleep every time I lay down to go to sleep and it's not even that much that comes out. I usually wake up at least once to urinate and I am not drinking enough water to cause this. I also feel tired all the time and have been losing what seems more than usual amounts of hair. I have Hoshimoto's Thyroiditis and recently got diagnosed with sarcoidosis. Are these symptoms worth stressing over or should I wait until my next checkup to see if they subside over time?
