Is hypothyroidism related to pituitary and thymus?

Is hypothyroidism related to pituitary and thymus?

Partly: The pituitary directs the body's glands to produce hormones and thus a defect in the signaling system to the thyroid may cause hypothyroidism. The thymus is more concerned with immune processing and has no direct role in hypothyroidism. ...Read more

Hypothyroidism (Definition)

The thyroid gland is an endocrine organ located in the front part of the neck. Its role is to make thyroid hormones, which control the way cells use energy. Hyperthyroidism results when the thyroid gland is overactive and too much thyroid hormone is produced, which speeds up metabolism. This results in weight loss, a quick heartbeat, sweating, nervousness, ...Read more

Doubt pituitary: You have headaches. Hopefully your hypothyroidism is being adequately treated. Why do you think this is from your pituitary? A pituitary headache is relatively unusual, and usually is associated with a relatively large tumor. See your doctor about the cause of your headaches. ...Read more

Endo feedback: With primary hypothyroidism, TSH is elevated in an effort to push the thyroid gland to make more thyroxine. Treatment with levothyroxine indeed signals the pituitary to reduce TSH output. Secondary is when either/or pituitary +/- hypothalamus is damaged but unable to produce tsh. Then, thyroxine levels drop but the pituitary can't respond. Tsh can't monitor treatment but free T4 levels can. ...Read more

I've been hypothyroid for several years, currently on 240mcg armour. Ultrasound revealed an "enlarged & lumpy" thyroid gland. What can this?

I've been hypothyroid for several years, currently on 240mcg armour. Ultrasound revealed an "enlarged & lumpy" thyroid gland.  What can this?

?goiter: Not really sure what this non-descriptive ultrasound is revealing, but it may be cysts, or nodules, or a "generic goiter" causing your enlargement. Have a thyroid specialist (endocrine dr.) evaluate you to be safe. Sometimes a fine needle aspiration (fna) with biopsy may be needed to definitively diagnose it. Best wishes. ...Read more
