It increases your metabolic rate more than normal. the result of the diaorrhea and your hair loss. it makes your skin and mucous membranes dry and you lose weight. it even affects your bones in your case it's good that you have started medication. however I would advise you to go for ahomoepathic treatment as it is safe and the cure will be complete.
