i just got my most recent lab results,previously my thyroid results have been normal, i am now into my 16,s week on tx. my most recent labs show my thyroid stimulating level was found to be quite low. he is saying this may indicate an overactive thyroid, does that mean i will lose weight. this sounds more like hypoactive thyroid to me . he is sending me for T3,T4,free T4, anti-thyroglobulin antibody and anti-thyroid peroxidase antibody levels.
I've done the thyroiditis thing from txing! Mine hit about week #10 and continued for about 10 weeks until it "flipped" to hypothyroid.
So, here's a crash course in thyroid labs...The lower the TSH number, the more "hyper" (overactive) your thyroid is. Your "frees" (free-T-3, Free T-4) will be super high. This causes heart palpitations, rising blood pressure, headaches, hot flashes and night sweats. During treatment it also accelerates the hemolytic anemia (not correctable by iron supplements). You may or may not lose weight (I didn't). The ultimate danger is when the symptoms (the rapid heart beats and blood presssure suddenly rise out of control (Rare, but it is called a "thyroid storm" which is a true emergency as it causes a sudden spike in heart rate (over 130 beats -often 160), makes your body temp rise to fever levels (mine hit 102 F) and can make your blood pressure go so high you have a stroke. the good news is, if your symptoms become severe, you can take a Beta blocker medicine (slows everything down until the thyroiditis is over) and you won't have to stop treatment...~MM
