Physical examination and change in body weight are used to diagnose ascites, what other measurement is used?

Choice A reason: Polydipsia refers to excessive thirst, polyuria refers to frequent urination, polyphagia refers to increased hunger, weight loss often occurs despite an increased appetite, and fatigue is a common symptom due to the body's inability to properly use glucose for energy. These symptoms are classic early signs of type 1 diabetes and occur because the body cannot produce enough insulin to regulate blood sugar levels.

Choice B reason: While weakness, vomiting, hypotension, and mental confusion can be symptoms associated with diabetic ketoacidosis (a serious complication of diabetes), they are not typically the earliest signs of type 1 diabetes. These symptoms may develop later if diabetes is not managed properly.

Choice C reason: Recurrent infections, visual changes, and paresthesia can occur in individuals with diabetes, but they are more common in long-standing diabetes and are not the earliest signs. These symptoms result from chronic high blood sugar levels affecting various body systems.

Choice D reason: Vomiting, abdominal pain, sweet, fruity breath, dehydration, and Kussmaul breathing are symptoms of diabetic ketoacidosis (DKA), a severe and life-threatening complication of diabetes. While these symptoms can occur in individuals with type 1 diabetes, they are not the initial signs but rather indicators of an advanced and poorly controlled condition.

Choice A reason: Type 1 diabetes is not characterized by the stimulation of glucose production due to food intake and resulting in increased insulin production. This description is more relevant to normal metabolic processes rather than the pathophysiological mechanisms underlying type 1 diabetes.

Choice B reason: The pathophysiology of type 1 diabetes is not due to decreased production of releasing hormones by the hypothalamus. While hormonal regulation plays a role in overall endocrine function, type 1 diabetes specifically involves the pancreatic islet cells.

Choice C reason: Type 1 diabetes is an autoimmune disorder where the body's immune system attacks and destroys the insulin-producing beta cells in the pancreatic islets. This destruction leads to a deficiency of insulin, which is necessary for regulating blood glucose levels. As a result, individuals with type 1 diabetes must rely on exogenous insulin to manage their blood sugar levels.

Choice D reason: Insulin resistance, where insulin-sensitive tissues do not respond effectively to insulin, is a characteristic of type 2 diabetes, not type 1 diabetes. In type 1 diabetes, the issue is the lack of insulin production due to the destruction of the pancreatic islet cells.
