She is convinced that her lack of menstrual periods is the cause of her infertility. Tonya's height is 5'5" and she weighs 107 lbs, which she has maintained for 4 years (she previously weighed 121 lbs). Her FSH and LH levels are both abnormally low, and she is not ovulating. When the importance and methods of weight gain are explained to her, Tonya agrees to gain some weight. After she regains 7 lbs, her LH is normal, but her FSH level is still low, and the luteal phase of her cycles is abnormally short. When her weight reaches 119 lbs, Tonya's LH and FSH levels, ovulation, and menstrual cycles all normalize. QUESTIONS: 1. Was Tonya underweight or normal weight based on her BMI when she was 107 lbs? 2. Can you determine Tonya's body fat content based on her BMI?

there is no category for nutrition that's why I chose nursing.

Answer 1

1, Ibs to kg
Weight 107Ibs = 49 kg
height 5'5 = 1.65m
BMI = weight (kg) divided into height 2(m2)
= 49 divided by (1.65 X 1.65)
= 49 divided by 2.7
= 18
BMI below 18.5 considered as an Underweight.
2, Body fat percentage(BFP)
=1.20 X BMI + 0.23 X age -5.4
3, when people are underweight there will be less FSH and LH production due to hypothalamic production which leads to hypogonadotropic hypogonadism. Hypothalamus may not produce a gonadotropin-releasing hormone that stimulates pituitary glands to produce the hormone and stimulate ovulation(FSH and LH).
4, When Tonya's weight decreased and considered as underweight her estrogen level will be low which cause amenorrhea. female hormones like estrogen and progesterone help regulate the menstural period.
5, Being underweight can interfere with the production of FSH and LH hormone. Tonya should increase her weight up to a normal level which stimulates ovaries to produce the follicles which produce mature eggs and progesterone that help to maintain a pregnancy. Clomid or other fertility drugs have a lot of side effects and ovarian and endometrial cancers.
