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.

Endocrine and Metabolic Disorders Questions
What are some of the things that can disrupt melatonin production in children?
-
Exposure to bright light before bedtime
-
Caffeine consumption
-
Irregular sleep schedule
-
All of the above
D
Correct answer
Explanation
Exposure to bright light before bedtime, caffeine consumption, and irregular sleep schedule can all disrupt melatonin production in children.
Which of the following is a chronic disease that affects the endocrine system and can cause diabetes, thyroid disease, and Cushing's syndrome?
-
Addison's disease
-
Pituitary gland disorder
-
Parathyroid gland disorder
-
All of the above
D
Correct answer
Explanation
Addison's disease, pituitary gland disorder, parathyroid gland disorder, diabetes, thyroid disease, and Cushing's syndrome are all chronic endocrine diseases. Addison's disease is a condition in which the adrenal glands do not produce enough hormones. Pituitary gland disorder is a condition in which the pituitary gland does not produce enough hormones. Parathyroid gland disorder is a condition in which the parathyroid glands do not produce enough hormones. Diabetes is a condition in which the body does not produce enough insulin or does not use insulin well. Thyroid disease is a condition in which the thyroid gland does not produce enough hormones or produces too many hormones. Cushing's syndrome is a condition in which the body produces too much cortisol.
Which type of Diabetes is characterized by the body's inability to produce insulin?
-
Type 1 Diabetes
-
Type 2 Diabetes
-
Gestational Diabetes
-
Secondary Diabetes
A
Correct answer
Explanation
Type 1 Diabetes, previously known as juvenile diabetes or insulin-dependent diabetes, is an autoimmune disease in which the body's immune system attacks and destroys the insulin-producing beta cells in the pancreas, leading to an absolute deficiency of insulin.
What is the term used to describe abnormally high levels of glucose in the blood?
-
Hyperglycemia
-
Hypoglycemia
-
Glycosuria
-
Ketosis
A
Correct answer
Explanation
Hyperglycemia refers to abnormally high levels of glucose in the blood, typically above 180 mg/dL. It is a characteristic feature of Diabetes Mellitus.
What is the term used to describe abnormally low levels of glucose in the blood?
-
Hyperglycemia
-
Hypoglycemia
-
Glycosuria
-
Ketosis
B
Correct answer
Explanation
Hypoglycemia refers to abnormally low levels of glucose in the blood, typically below 70 mg/dL. It can occur in individuals with Diabetes who take too much insulin or skip meals.
Which type of Diabetes is characterized by insulin resistance?
-
Type 1 Diabetes
-
Type 2 Diabetes
-
Gestational Diabetes
-
Secondary Diabetes
B
Correct answer
Explanation
Type 2 Diabetes, previously known as adult-onset or non-insulin-dependent diabetes, is characterized by insulin resistance, where the body's cells do not respond properly to insulin, leading to elevated blood sugar levels.
What is the term used to describe a condition in which the body produces antibodies that attack and destroy the insulin-producing beta cells in the pancreas?
-
Type 1 Diabetes
-
Type 2 Diabetes
-
Gestational Diabetes
-
Secondary Diabetes
A
Correct answer
Explanation
Type 1 Diabetes is an autoimmune disease in which the body produces antibodies that attack and destroy the insulin-producing beta cells in the pancreas, leading to an absolute deficiency of insulin.
The Neuroendocrine Theory of aging suggests that:
-
Aging is caused by changes in the neuroendocrine system, including the hypothalamus, pituitary gland, and adrenal glands.
-
These changes can lead to a decline in hormone production.
-
Declining hormone levels can have a variety of effects on the body, including changes in metabolism, reproduction, and immune function.
-
All of the above.
D
Correct answer
Explanation
The Neuroendocrine Theory proposes that aging is caused by changes in the neuroendocrine system, including the hypothalamus, pituitary gland, and adrenal glands. These changes can lead to a decline in hormone production, which can have a variety of effects on the body, including changes in metabolism, reproduction, and immune function.
What is the name of the disorder characterized by excessive production of cortisol?
-
Cushing's syndrome
-
Addison's disease
-
Pheochromocytoma
-
Hyperthyroidism
A
Correct answer
Explanation
Cushing's syndrome is a disorder caused by excessive production of cortisol.
What is the name of the disorder characterized by insufficient production of cortisol?
-
Cushing's syndrome
-
Addison's disease
-
Pheochromocytoma
-
Hyperthyroidism
B
Correct answer
Explanation
Addison's disease is a disorder caused by insufficient production of cortisol.
What is the name of the disorder characterized by excessive production of epinephrine?
-
Cushing's syndrome
-
Addison's disease
-
Pheochromocytoma
-
Hyperthyroidism
C
Correct answer
Explanation
Pheochromocytoma is a disorder characterized by excessive production of epinephrine.
What is the name of the disorder characterized by insufficient production of aldosterone?
-
Cushing's syndrome
-
Addison's disease
-
Pheochromocytoma
-
Hyperthyroidism
B
Correct answer
Explanation
Addison's disease is a disorder characterized by insufficient production of aldosterone.
Which autoimmune disease affects the thyroid gland, leading to abnormal thyroid hormone production?
-
Graves' disease
-
Hashimoto's thyroiditis
-
Sjögren's syndrome
-
Celiac disease
A
Correct answer
Explanation
Graves' disease is an autoimmune disease that causes an overactive thyroid gland, leading to increased thyroid hormone production and symptoms such as weight loss, anxiety, and heart palpitations.
Which autoimmune disease affects the adrenal glands, leading to hormonal imbalances?
-
Addison's disease
-
Cushing's syndrome
-
Polymyositis
-
Ulcerative colitis
A
Correct answer
Explanation
Addison's disease is an autoimmune disease that affects the adrenal glands, leading to a deficiency of hormones such as cortisol and aldosterone, resulting in fatigue, weight loss, and low blood pressure.
