An insulinoma is a tumor of the pancreas that secretes insulin. The beta cells in the pancrease (pancrelipase) secrete Insulin in response to high glucose levels in the blood. Since an insulinoma is a collection of abnormal cells, an insulinoma will produce Insulin regardless of the blood glucose levels and can cause profound hypoglycemia ...Read more
Hormones: A tropic hormone is a hormone secreted by one gland and then stimulates another gland; for example, the pituitary makes TSH, which targets the thyroid and causes the thyroid to make T4 and T3 (liothyronine). The thyroid hormones (T4, T3 (liothyronine)) target other organs (heart, CNS, GI, etc), but not really other glands, so are not really tropic hormones. ...Read more

Basal glucose =81 mg/dl but insuline =38 mU/ml (insuline/glucose > 0,3 ). Symptoms of ipoglycemia... How to exclude an insulinoma? Ultrasound?thanks!
Hypoglycemia: To diagnose insulinoma, you need to demonstrate inappropriately high insulin/C-peptide when your glucose is low. A glu of 81 is not low, it is normal. You have symptoms of hypo, but these symptoms are often from something else. Insulinoma is rare. Do not start getting CT/ultrasound etc until you establish the biochemical diagnosis first. An Endocrinologist can help you. ...Read more

Are high LH (90 MIU/ML) and FSH (168 MIU/ML) in a post menopausal woman indicative of pituitary disease? (Normal Prolactin, Cortisol (am), TSH)
What pituitary hormones cause the adrenal gland to produce mineralocorticoids, glucocorticoids, and androgens and estrogens including pregnenolone?
Pituitary & steroids: Hi. Pituitary ACTH regulates adrenal cortisol production; it also acutely stimulates aldosterone, but is not the principle regulator. LH principally stimulates gonadal steroid hormone production (both genders make androgens & estrogens, but in opposite dominance). Pregnenolone is early in the steroidogenic pathway in both adrenals and gonads. Good luck! ...Read more
