Recently I have been facing problem with night sleep.. insomnia..I am not able to sleep before 3or 4..and not able to wake up in morning...my body's temperature is always stays low(my BP is mostly 60/90).. sluggishness, sudden weight gains, always low energy, weekness(may be because of low BP but I am not sure).. I get constipation very easily..hair loss, and very irregular periods, always pain in my calves. Please suggest something..because I am worried because all my problems are meeting to the symptoms of hyperthyroid.
