The Endocrine System

High blood sugar levels can indicate a hormonal disorder. Despite a normal body weight, a sedentary lifestyle may contribute to the development of metabolic issues, including insulin resistance. The condition that Mohit is likely suffering from is Type 2 Diabetes Mellitus. This disorder is characterized by high blood sugar levels resulting from insulin resistance, where the body's cells do not respond to insulin effectively. It is commonly associated with a sedentary lifestyle, unhealthy eating habits, and genetic factors.
Type 2 diabetes is typically diagnosed through blood tests measuring fasting blood glucose levels, HbA1c, or oral glucose tolerance tests. Lifestyle changes, including regular physical activity, a balanced diet, and possibly medication, are key to managing this condition.

(a) Hypersecretion of which hormone results in Adrenal Virilism in human females?
Adrenal Virilism in human females is caused by the hypersecretion of testosterone. This overproduction of testosterone by the adrenal glands leads to the development of male-like characteristics in females. (b) Mention one symptom of this disorder.
One of the common symptoms of Adrenal Virilism is the development of male secondary sexual characteristics in females, such as deepening of the voice and excessive growth of facial and body hair (hirsutism).

The Pancreas is the organ responsible for secreting insulin. It is located behind the stomach and plays a critical role in regulating blood sugar levels. The pancreas contains clusters of cells known as the islets of Langerhans, which are specialized to produce various hormones, including insulin. The Islets of Langerhans contain different types of cells, each responsible for secreting specific hormones: - Beta cells produce insulin, which lowers blood sugar levels. - Alpha cells produce glucagon, which raises blood sugar levels by stimulating the liver to release stored glucose. In a healthy individual, the pancreas maintains a balance between insulin and glucagon to regulate blood glucose levels. When blood sugar levels rise after eating, the pancreas releases insulin to help cells absorb glucose. In individuals with Type 2 Diabetes, the body’s cells do not respond to insulin as effectively, and the pancreas may produce more insulin to compensate. Over time, the pancreas may struggle to keep up with the demand for insulin production, leading to chronically high blood sugar levels. In some cases of Type 2 Diabetes, the beta cells in the pancreas become exhausted from constantly producing high amounts of insulin, which leads to a further decline in insulin production. This makes it harder for the body to regulate blood glucose levels, resulting in the need for external insulin therapy in advanced stages.

The hormonal disorder Mohit is likely suffering from is Type 2 Diabetes Mellitus. This disorder is associated with an imbalance in insulin production or its efficiency in the body. The key hormone responsible for regulating blood sugar levels is Insulin. Insulin is produced by the pancreas and plays a crucial role in regulating glucose metabolism by facilitating the uptake of glucose into the cells for energy production. Insulin helps lower blood sugar levels by promoting the absorption of glucose by muscle and fat cells and by stimulating the liver to store glucose as glycogen. In Type 2 Diabetes, the body becomes resistant to insulin, meaning the cells no longer respond to it effectively. This resistance forces the pancreas to produce more insulin to compensate for the inability of cells to respond. Over time, the pancreas may not be able to keep up with the demand, leading to high blood sugar levels, or hyperglycemia. The key characteristic of Type 2 Diabetes is insulin resistance, where the body’s cells, particularly muscle and fat cells, fail to respond to insulin properly. As a result, glucose builds up in the bloodstream, leading to the symptoms and long-term complications associated with the disorder. Insulin resistance can be influenced by various factors such as poor diet, lack of physical activity, obesity, and genetic predisposition.

Leukoderma is a skin condition characterized by the loss of pigmentation in certain areas, leading to white patches. It is not the biological term for blood cancer. The correct biological term for blood cancer is leukemia, not leukoderma. Therefore, Assertion (A) is false. The reason states that an abnormal increase in the number of WBCs (white blood cells) causes blood cancer. This is partially true, as leukemia (a type of blood cancer) is characterized by the abnormal increase in WBCs. However, the statement is not fully correct, as other factors contribute to blood cancer, and not all cases of abnormal WBC increases lead to leukemia. Therefore, Reason (R) is false. Since Assertion (A) is false and Reason (R) is also false, the correct answer is (A) that Assertion (A) is true and Reason (R) is false. Final Answer: (A) (A) is true and (R) is false.
