Class: Thyroid
Risk Factor: A
Fetal Risk Summary
Thyroid contains the two thyroid hormones levothyroxine (T4) and liothyronine (T3) plus other materials peculiar to the thyroid gland. It is used during pregnancy for the treatment of hypothyroidism. Neither T4 nor T3 crosses the placenta when physiologic serum concentrations are present in the mother (see Levothyroxine and Liothyronine). In one report, however, two patients, each of whom had produced two cretins in previous pregnancies, were given huge amounts of thyroid, up to 1600 mg/day or more (1). Both newborns were normal at birth even though one was found to be athyroid. The authors concluded that sufficient hormone was transported to the fetuses to prevent hypothyroidism.
Congenital defects have been reported with the use of thyroid but are thought to be caused by maternal hypothyroidism or other factors (see Levothyroxine and Liothyronine).
In a surveillance study of Michigan Medicaid recipients involving 229,101 completed pregnancies conducted between 1985 and 1992, 44 newborns had been exposed to thyroid during the 1st trimester (F. Rosa, personal communication, FDA, 1993). One (2.3%) major birth defect (two expected), a cardiovascular defect (0.5 expected), was observed.
Combination therapy with thyroid-antithyroid drugs was advocated at one time for the treatment of hyperthyroidism but is now considered inappropriate (see Propylthiouracil).

Q&A about Thyroid
my mom keeps complaining about some kind of a thyroid disorder' she keeps asking me that is there a some kind of a thyroid diseases where you feel hungrey and you gain weight and you feel something in you throat'is it a contagious diseases..........I dont know anything about it so please help
many women have thyroid problems , less men.
She needs to see a dr. and have a blood test taken. This is easily diganosed and not a problem to control with the proper meds.
Weight gain and tiredness go along with thyroid disease that is not treated. Good luck
I take thyroid medicine and it seems that when I started taking thyroid medicine years ago I started putting on weight. Now I am quite a bit overweight. Nothing seems to help. My thyroid has never been regulated right. Doctors just don't seem to pay much attention when I bring this up.
I'm severely hypothyroid. Without meds my TSH is 128 (normal is 4-10'ish). I still lost 198 lbs in 11 months on the Kimkins diet, which is low calorie low carb. Another member, Lynda, lost 213 lbs in 10 months (see her story below).
If you have insurance ask for a referral to an endocrinologist. It's not just about body weight, your thyroid regulates every single organ in your body, including your heart and liver (cholesterol).
I noticed a pea sized nodule on my throat, thyroid. I have had an ultrsound and needle biopsy. The biopsy showed abnormal cells so I am going to have surgery to remove the thyroid. What takes place in this surgery? Don't know what to expect!! Kinda scared too!
A friend of mine have part of her thyroid being removed several years ago (not sure exactly why), and logically she's having hypothyroidism problem currently, although the doctor gave her medicine to meet the requirement.
Anyone know how to fix this problem?
Thanks.
My docotor is testing my blood for thyroid problems, and I would like to know what treatments they may suggest if I do have any problems. Also, what are the possible issues with my thyroid that they may be checking for? Signs and symptoms? Not sure if this makes a difference, but I am a 22 yr old female - two children/c-section.
I have given several links below to read & perhaps you can read through & understand the different thyroid symptoms & problems.
Here is some information about myself, plus some symptoms since you seemed to be interested:
I have low thyroid. I've had it for 10 years. I got it after I had my second child at about the age of 25. If you have low thyroid...here's a great question to answer: Can you see the floor of your house? That was what was asked of me at one point, and to my amazement, the answer was no!
My signs are: messy house, no desire to do anything...go anywhere, spend time with my kids or my guy, sleep a lot, hard to keep my eyes open at times, HUGE weight gain that over the past years have not found an easy way to take off...so I give up a lot, I have terribly dry hair & don't wash it a lot so it stays strong, I have bumps on my face...not like pimples, but I think it's from dry skin, and perhaps some others that I can't remember at this time...that's another symptom--forgetfullness.
Here are the "GENERAL" signs for most people: fatigue and lack of energy. Women suffering from underactive thyroid experience heavier menstrual periods. Sluggishness and forgetfulness are symptoms of underactive thyroid problem. Other symptoms of this thyroid disorder are dry skin and hair and constipation.
If you have high thyroid, or an overactive one, the signs are: increased body metabolism. This is followed by weight loss and excessive warmth and sweating. Persons suffering from overactive thyroid experience trembling hands, irritability and rapid heartbeat or palpitations. Women with overactive thyroid or hyperthyroidism may experience shorter or lighter menstrual periods.
I take medication, and sadly will have to take 1 pill everyday for the rest of my life. There's a blood check that they will do to see if you have low or high. I hope i've helped you!!
My daughter's tyroid seem enlarged and I was curious if she may have an underactive thyroid. She had gained weight in the last year.
o tiredness & fatigue
o depression
o irritability
o weight gain
o muscle weakness and cramps
o intolerance to cold weather
o deteriorating or slowing growth rate
o constipation
o dry, coarse, itchy skin
o brittle hair
o a croaky, hoarse voice
o slow reflexes
o slow heart rate
o delayed as well as precocious sexual development
o high cholesterol levels
o girls may suffer from increased menstrual flow
NB: children and adolescents with under activity of the thyroid may have almost no symptoms or signs other than weight gain or slowing growth.
I have developed several large & many small nodules on both thyroid glands. The Dr. wants to remove them. What could cause this? What % of the time are they cancerous cells?
My regular doctor has me on thyroid supplement for normal but low thyroid. My symptoms (normal body temperature but freezing all the time) are not helped. There are supposedly thyroid problems that are not detected by regular blood tests. What type of doctor does the more involved thyroid testing?
My 6-year-old Cocker Spaniel has a T4 thyroid level of 0.6 so he's been put on 0.5 thyroxine daily. How long until I see a noticeable improvement in his skin, ears and behaviour (slight aggressive tendency)? Is this an 'overnight fix' like human hormones can be, or will it take a while to build up in his system?
You'll notice a change in the energy level in a day or so. The coat takes time.
You'll also have to revisit your vet for more blood work in about a month to see if the level is correct.
My experience with Levothyroxine and/or Soloxane has all been very positive.
I had a blood test done last week and it came back abnormal for the thyroid. The doctor put me on a medicine called Synthroid for it. If someone can tell me in simple terms, I would appreciate it!
