I am diagnosed with anemia, iron deficiency. I wake up frequently at night to use bathroom. Sometimes when I get up , i am sweaty n dizzy n heart races. Sometimes I get up n am okay but when I lay down , I start sweating, heart races, feel nausea, sometimes body aches. Then I get chilled n have to cover up again. Also after I eat my heart races, sometimes nausea. Also, is it harder to burn calories when anemic, do u have to exercise twice as long.? Just can t loose as much weight
