Do I have hypothyroidism, or what ? I am always extremely tired, especially in the evenings. I need a nap if you slept 9 or 10 hours of night . I have depression. I suffer a lot of headaches and sometimes dizziness when I stand up.

Although fatigue is a typical symptom of hypothyroidism, may be many other things happening here. For example, fatigue could simply be a manifestation of depression. It could also be due to sleep apnea. People with sleep apnea - a common cause of daytime tiredness - often say that sleep 8-10 hours a night, but sleep studies reveal that the break usually be interrupted by frequent episodes of apnea - sometimes up to 100 times each night. Your sore throat could also be another clue to the cause of daytime tiredness: individuals with GERD may experience sleep disruption due to frequent episodes of acid-hours reflux, and the only symptom of the underlying problem is the pain throat in the morning. You should see your doctor for an evaluation. In addition to causing daytime tiredness, lack or chronic Sleep disruption may cause an increased risk of their other problems, such as heart disease.
