Re: Please help - what do these test results mean?
I'm not familiar with some of the results you got as lab ranges vary from country to country. You might need to post your lab range so that others might be able to see what is going on.
I can say though that your ferritin (iron stores) is at the very low end of the lab range. I would begin iron supplements. YOu can get a lot more information on this in the Anemia section of these Healthboards.
As your ferritin is low, there is a good chance your Vitamin D, B12, folate, zinc could be low. Low Vit D is extremely common and even hair shedding has been linked to this. Get your doctor to run a blood test for these too.
Low ferritin can contribute to abnormal hair shedding, but so can a variety of other things eg: hormonal imbalance, thyroid problems, nutritional deficiency due to malabsorption of nutrients which can occur due to either gluten intolerance or full blown Celiac disease, from digestive issues which can occur due to insufficient digestive enzymes and/or thyroid related problems. Birth control pills can deplete a person of vitamins, in particular the B group vitamins. So if you are on birth control you should be on a multivitamin daily. Birth control can mess up some people's hormones and can lead to hair shedding.
For gluten intolerance/Celiacs you can get a blood test to check for antibodies.
I would be getting my doctor to do a full thyroid panel test eg: TSH, Free T3, Free T4 and Thyroid Antibodies test to check whether you have an auto immune thyroid disease as this can be common too. With thyroid testing it gets tricky as a lot of doctors don't take symptoms into account, they simply check that your lab results are "within range", which isn't right, or they only look at your TSH levels which majority of the time count for nothing. This is how i went 9 years without being diagnosed and the whole time i was hypothyroid with the thyroid auto immune disease called Hashimoto's.
As my thyroid doctor says, hair shedding is the first sign of something being wrong internally and usually the last to recover.
