674 Questions

Endocrine and metabolic disorders focus on diseases caused by hormonal imbalances, such as goitre, diabetes mellitus, and hyperthyroidism. Test takers will find questions related to disease causes, diagnostic tests like Cushing's syndrome indicators, and clinical treatments. This is a crucial biology topic frequently asked in medical entrance and public service commission examinations.

A Correct answer
Explanation

Sodium depletion occurs in excessive sweating and cannot be corrected by drinking water alone. When uncorrected, it may lead to muscle cramps, loss of energy, fatigue and faintness.

Multiple choice
  1. Cells fail to respond to the normal actions of the hormone insulin.

  2. Body cells become resistant to insulin and cannot utilise it, further leading to latent autoimmune diabetes.

  3. Beta cells in the pancreas increase their production of insulin, further contributing to a high blood insulin level.

  4. All of the above

D Correct answer
Explanation

Insulin resistance (IR) is generally regarded as a pathological condition in which cells fail to respond to the normal actions of the hormone insulin. The body produces insulin when glucose starts to be released into the bloodstream from the digestion of carbohydrates in the diet. Normally, this insulin response triggers glucose being taken into body cells, to be used for energy and inhibits the body from using fat as energy. The level of glucose in the blood decreases as a result, staying within the normal range even when a large amount of carbohydrates is consumed. When the body produces insulin under conditions of insulin resistance, the cells in the body are resistant to the insulin and are unable to use it effectively. It leads to high blood sugar. Beta cells in the pancreas subsequently increase their production of insulin, further contributing to a high blood insulin level. This often remains undetected and can contribute to a diagnosis of Type 2 diabetes or latent autoimmune diabetes of adults. Although this type of chronic insulin resistance is harmful, during acute illness it is actually a well-evolved protective mechanism.

Multiple choice
  1. stein-leventhal syndrome

  2. cushing’s syndrome

  4. archard-thiers syndrome

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Archard-Thiers syndrome is a rare condition historically referred to as 'diabetes of the bearded woman' due to the combination of hirsutism and metabolic disturbances.

Multiple choice
  1. pituitary hypersecretion

  2. ovarian tumors

  3. adrenal tumors

  4. all of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Hirsutism is often caused by hormonal imbalances, which can stem from pituitary, ovarian, or adrenal issues. All of these glands can produce hormones that stimulate excess hair growth.

Multiple choice
  1. Iatric hirsutism

  2. Hereditary hirsutism

  3. Idiopathic hirsutism

  4. Familial hirsutism

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Idiopathic hirsutism refers to excess hair growth where no specific underlying cause, such as hormonal imbalance or medication, can be identified. The prefix 'idio-' implies a condition of unknown origin.

Multiple choice
  1. Iatric Hirsutism

  2. Familial Hirsutism

  3. Idiopathic Hirsutism

  4. Hereditary Hirsutism
