|
Q1369. How do you evaluate the cause of secondary amenorrhea? (If SUFFicient estrogen)
|
A1369. 1. Rule out pregnancy (check hCG); 2. Do H & P to look for obvious causes; 3. Administer progesterone to assess the patient's estrogen status. If vaginal bleeding develops within 2 weeks, the patient has sufficient estrogen. Check LH. If high, consider PCOS. If low or normal, check prolactin and TSH levels. High TSH levels in hypothyroidism cause high prolactin levels. If the prolactin is high with a normal TSH level, order an MR scan of the brain to rule out pituitary prolactinoma. If prolactin is normal, then look for low levels of GnRH, which may be induced by drugs, stress, or exercise. In these patients, clomiphene may be used to facilitate pregnancy.
|
|
|
Q1370. How do you evaluate the cause of secondary amenorrhea? (If INSUFFicient estrogen)
|
A1370. 1. Rule out pregnancy (check hCG); 2. Do H & P; 3. Administer progesterone. If no bleeding: estrogen levels are inadequate. 4. Check FSH. If elevated, premature ovarian failure is the problem, check for autoimmune disorders, karyotype abnormalities, history of chemotherapy. If FSH is low or normal, problem may be a brain tumor (craniopharyngioma). Order an MR of the brain.
|
|
|
Q1371. When do you suspect primary amenorrhea?

|
|
Q1372. What is the algorhythm for diagnosing the cause of amenorrhea?
