Lab 5 Endocrine Physiology
Part 1: Analysis of Hormonal Effects
Hormonal Effects Case 1
A male patient enters your office. He is in his mid-30s and in decent physical shape. He
complains about being tired and seems to be gaining some weight, while not eating more than
normal. He also describes being cold all the time. You decide to perform a blood test and receive
the following results. After reviewing his results, you come to a conclusion. What might be
wrong with this patient and how does this diagnosis correlate with the symptoms presented by
the patient?
Hypothyroidism is the diagnosis. The classic symptoms of hypothyroidism are fatigue, weight
gain while not eating, and persistent coldness. Your metabolism slows down and your thyroid
produces less hormones when you have hypothyroidism. As a result, you won't lose weight as
quickly from calorie intake. Since these hormones are in charge of controlling metabolism and
body temperature, cold intolerance is a well-known sign of hypothyroidism. You might feel
exhausted if you have hypothyroidism due to lower energy. In the more rare incidence of
hypothyroidism caused by pituitary failure, the thyroid hormone T4 will be low but the TSH
level will also be low. Normally, high TSH levels can indicate that your thyroid is not producing
enough thyroid hormones, a disease known as hypothyroidism. This could be the cause of the
low TSH levels observed in this case.
Part 2: Determining Hormonal Imbalance
Hormonal Imbalance Case 1
A 38-year-old male patient enters the office complaining about muscle twitches and feeling on
edge. His pupils are dilated, and he notes an increase in body temperature. What hormone could
be outside normal values and why?
Elevated adrenaline levels brought on by stress, anxiety, or other underlying reasons could be a
possible cause of the 38-year-old male patient's muscle spasms, increased anxiety, dilated pupils,
and raised body temperature. The body's reaction to stress or perceived threat is manifested by
elevated epinephrine levels, and the symptoms that follow are due to the physiological
modifications brought on by the "fight-or-flight" response that is mediated by this hormone.
