I am a 24-year-old female, in quite good shape (5'6", 130 lb) but with extremely high cholesterol. At one point it was 310, which prompted screening for hypothyroidism (and my grandmother has Hashi's). At that point my TSH was 4.02 (range here in Thailand: 0.97 - 4.20). After talking with the dr. and realizing I had many of the common symptoms (fatigue, constipation, headaches, frequent infections, anemia, low blood sugar) I was put on a half tablet of Synthroid, as well as a cholesterol-lowering drug.
Now about 3 months later, my cholesterol is still at 265, despite watching my diet, taking the meds faithfully and exercising regularly. My TSH is 1.75, my free T4 is in range but on the low side. My doc seems to go by the test numbers so is not adjusting anything. I have a bit more energy, but still cannot stay healthy, am usually constipated and headachy, and in general just don't feel well.
Can a TSH at this level be causing these symptoms and the high cholesterol? Should I insist on an increased dosage? Also, I have not been tested for antibodies, though Hashi's is the type of hypothyroidism in my family. Would it be worth testing for this? Or would treatment probably stay the same? Thanks for any input.
