After four years of experiencing amenorrhea, Tonya seeks medical care to help her become pregnane. She is convinced that her lack of menstrual periods is the cause of her infertility. Tonya’s height is 5 ft 5 in.; her weight is 107 pounds, which she has maintained for four years (she previously weighed 121 pounds). 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 pounds, her LH level is normal, but her FSH level is still low, and the luteal phase of her cycles is abnormally short. When her weight reaches 119 pounds, Tonya’s LH and FSH levels, ovulation, and menstrual cycles are normal.

What likely happened to Tonya’s average estrogen level when her weight decreased from 121 to 107 pounds?

Summary Introduction

To explain: The event that likely happened to Person T’s average estrogen level when her weight decreased from 121 to 107 pounds.

Introduction: Body mass index (BMI) is obtained by dividing weight (Kg) by square of height (in m). If BMI is greater than 18.5, then it is considered underweight, 18.5-24.9 comes under normal weight, people with 25-29.9 are overweight, and people with BMI of 30 and higher are considered obese.

After sometime, she regains 7 pounds, and her LH level becomes normal, but her FSH level is still low, and the luteal phase of her cycles is abnormally short. When her weight reaches 119 pounds (53.97 kg), her LH, FSH levels, ovulation, and menstrual cycles become normal...
