25y/o male w/prolactinoma. Thyroid bloodwork normal. Doc says thyroid slightly swollen. Body temp 97.5 oral/feel cold a lot. How is hypothyroid diagnose?

Thyroid prolactin: Hypothyroid is diagnosed with thyroid blood tests. You would expect an elevated TSH and a low free t4. There is an interaction between thyroid and prolactin. If you are hypothyroid and have an elevated tsh, this will raise the prolactin; correcting the thyroid will normalize the prolactin. But this may not apply to you. The "swollen thyroid" may be separate. See your endocrinologist. ...Read more

My prolactin lvl was high. For more than 2years. I did nothing. What can I do to decrease the prolactinoma. Use pergabalin? Am a male. Single.24years

I don't know: What "high" means numerically. Is your level still high? When you say prolactinoma, has that been demonstrated by CT or MRI? If so, the best medication is cabergoline. Pregabalin won't help. Check w/your doctor or see an endocrinologist, There are many medications which can cause elevated prolactin levels, as well as hypothyroidism. ...Read more

Prolactine has been elevated double the upper normal range for years. Trh test showed no increase in prolactine. Is this proving for prolactinoma?

Prolactine has been elevated double the upper normal range for years. Trh test showed no increase in prolactine. Is this proving for prolactinoma?

Probably: Hi. Or Tschüss! You most likely have a micro-adenoma (small prolactin-producing benign tumor). There are some medication that increase prolactin (PRL) such as anti-dopaminergics or narcotics; you could check with an endocrinologist to see if any meds you're on could. Pituitary stalk compression/compromise is much less likely in your clinical condition, I would think. ...Read more
