Jane has been feeling tired, has cold and gained a bit weight and trouble concentrating. what hormone problem symptoms is this ​
ipn [44]

The hormones which cause Jane’s problem are the thyroid hormones.

The condition is hypothyroidism

Explanation:

Condition:  Hypothyroidism is an endocrine disorder which arises when the thyroid gland cannot produce the necessary amount of thyroid hormones like thyroxine (T4) and triiodothyronine (T3).  

Both T3 and T4 are tyrosine-based hormones which regulate metabolism and any deficiency slows down the metabolic processes and can result in high cholesterol levels and atherosclerosis

Causes:  An underactive thyroid gland  and Autoimmune disorder

Diagnosis:  Thyroid function tests by measuring serum thyroid stimulating hormone (TSH) and T4 levels

In hypothyroidism, the TSH secreted by the pituitary gland will be high because it is producing more hormones to stimulate the underactive thyroid gland.

An underactive thyroid gland cannot produce normal levels of T4 in the body.

Symptoms:  Fatigue and weakness, cold intolerance, weight gain and puffy appearance, hair thinning, dry skin, decreased concentration, poor memory, muscle and body aches etc.

Treatment : Hormone replacement therapy with levothyroxine
