It is difficult to tell what is the cause of your problem without more information, but perimenopause is a likely cause. Heart palpitations are common and can make a person feel dizzy and tired. Low blood sugar is another common cause.
Early in perimenopause, estrogen levels are actually normal or high and progesterone is low. Some women benefit from taking a low dose of progesterone. If it is possible, when you are feeling your symptoms, try to see your doctor and have your heart rate checked along with your hormone levels blood glucose level. That may be a good way to be sure what is causing the problem.
