Sara Gottfried Hormone Quiz
Questions: 16 · 10 minutes
1. After a carbohydrate-containing meal, blood glucose rises. What is one key action of insulin in this situation?
It signals the thyroid to release more T4 immediately
It converts glucose directly into cortisol in the bloodstream
It prevents the liver and muscles from storing any glucose
It helps responsive cells take up glucose and promotes energy storage
2. A person wants to know whether blood, saliva, or urine is always the best way to measure hormones. What is the most accurate answer?
Saliva is always superior because hormones never vary during the day
The appropriate sample depends on the hormone, clinical question, timing, and validated use of the test
Urine is always superior because it directly measures every active hormone in real time
All sample types are interchangeable if they are collected on the same day
3. A person is starting a combined hormonal contraceptive shortly before planned hormone testing. What is the most useful step?
Tell the ordering clinician, because hormonal contraception can affect some measurements and their interpretation
Stop it without guidance several days before every hormone test
Assume it cannot affect any measured hormone or binding protein
Double the contraceptive dose so the results are easier to interpret
4. Which statement about polycystic ovary syndrome (PCOS) is most accurate?
It can involve ovulatory dysfunction and androgen-related features; ovarian cysts are not required in every case
It always causes the same symptoms and hormone levels in everyone
It is diagnosed whenever an ultrasound finds any ovarian follicle
It is primarily a disorder in which the thyroid stops producing hormones
5. In clinical use, natural menopause is generally identified retrospectively after what has occurred, assuming there is no other cause?
Three months without a menstrual period
One unusually light menstrual period after age 40
Twelve consecutive months without a menstrual period
A single blood test showing low estrogen
6. A 46-year-old has several shorter cycles, then a longer cycle, followed by two fairly regular cycles. Which interpretation is most accurate?
Menopause has definitely occurred because one cycle was delayed
Cycle variation at this age proves that ovarian hormones have stopped permanently
The pattern can only be explained by a thyroid disorder
Perimenopause can involve fluctuating hormones and changing cycle patterns before periods cease
7. If circulating thyroid hormone becomes lower than the body needs and the feedback system is responding normally, what would the pituitary typically do?
Release more insulin to activate the thyroid
Increase thyroid-stimulating hormone (TSH) signaling
Release an LH surge to increase thyroid activity
Stop all communication with the thyroid gland
8. What is the best general description of a hormone?
A nutrient used only to provide energy to endocrine glands
An enzyme that permanently changes every cell it contacts
A chemical messenger that travels to influence cells with suitable receptors
An antibody produced specifically to control metabolism
9. After ovulation, which structure is the main temporary source of progesterone during the luteal phase?
The thyroid gland
The corpus luteum
The anterior pituitary
The uterine lining
10. What does the term “endocrine-disrupting chemical” generally mean?
A substance that can interfere with some aspect of hormone production, action, transport, or metabolism
Any chemical that immediately destroys an endocrine gland
A natural hormone that is produced only during stress
A substance that causes the same hormone symptoms in every exposed person
11. Which gland-and-hormone pairing is correct?
Pancreas — cortisol
Pituitary gland — estrogen
Adrenal cortex — insulin
Thyroid gland — thyroxine (T4)
12. Someone develops a sudden severe headache with major vision changes and wonders whether hormones could be involved. What is the appropriate response?
Seek urgent medical assessment rather than relying on a quiz or self-treatment
Begin an over-the-counter hormone supplement and check for improvement
Wait for a routine hormone panel because testing should come before examination
Track the symptoms for several weeks before deciding whether to seek care
13. Someone has been sleeping much less than usual for several weeks. Which effect is biologically plausible?
Sleep loss permanently switches off cortisol production
Sleep loss guarantees clinical hypothyroidism
Sleep loss may affect appetite signaling and glucose regulation
Sleep loss causes estrogen and testosterone to become identical
14. Fatigue, sleep changes, and weight changes can occur with hormone conditions but also with many other issues. What is the soundest conclusion?
Symptoms are more diagnostically reliable than medical history or testing
Any one of these symptoms confirms a cortisol disorder
Symptoms need context and may require a broader professional assessment rather than a hormone-only assumption
All such symptoms are normal and never need evaluation
15. Which statement best reflects mainstream medical understanding of “adrenal fatigue”?
It is another name for every temporary rise in cortisol
It can be confirmed by symptoms alone without considering other causes
It means the adrenal glands have permanently stopped working in anyone who feels tired
It is not an established medical diagnosis, while adrenal insufficiency is a real condition requiring proper evaluation
16. Which hormonal event most directly triggers ovulation in a typical menstrual cycle?
A sustained fall in insulin
A surge in luteinizing hormone (LH)
A surge in thyroid-stimulating hormone
A sudden elimination of cortisol
