You have a friend who became stranded in a blizzard without food for
Naya [18.7K]

The fat didn't really leave his body. Fat was converted to glucose in the gluconeogenesis pathway to give him energy during the period of starvation.

Fat is stored in the body in the adipose tissue. Fat plays so many roles in the body such as;

  • Protection of vital organs
  • Insulating the body from cold
  • Serving as an energy store

In times of starvation, fact could also be broken down to release energy. This occurs when fat is broken down to glycerol and fatty acids. When this occurs, glycerol goes to the liver where it is converted to glucose in the gluconeogenesis pathway. This helps to produce energy in times of starvation thereby depleting the body's fat reserve.

As this process occurs, the fat reserve in my friend's body kept going down resulting in his loss of about 15  Ibs of weight.

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
