Which of the following most accurately describes the pathophysiology of sepsis? A. More than one type of infectious agent invades the body, limiting the immune system's response to each agent.
B. An infectious agent in the body multiplies very rapidly, overwhelming the body's natural immune response.
C. Vasoconstriction and internal fluid retention lead to shock that does not respond to intravenous fluids.
D. The body overreacts to an infection and secretes substances that hurt cells, tissues, and organs.

The body overreacts to an infection and secretes substances that hurt cells, tissues, and organs.

Explanation:

Sepsis is a life-threatening condition resulting from an abnormal and counterproductive response by the body that causes damage to tissues and organs. The body overreacts and secretes substances that hurt the body. Septic shock occurs when these changes result in shock and hypotension that do not respond to intravenous fluid.

don't worry, but do consult a doctor.

explanation:

having a high metabolism at age 13 is not abnormal.   however, if you are concerned, do consult a doctor.   the doctor may identify a correctable issue, and then you'll have your answer.   in the meantime, there are a few steps you might consider.

first, reflect on just how much physical activity (work out and dancing) you are getting relative to your caloric intake.   keep in mind that if you are interested in gaining weight, you must have a higher caloric intake than output.   second, if eating robust healthy meals is not providing enough calories, you'll need to include high caloric, yet healthy, snacks.   i warn against using an over the counter high-calorie supplement (drink or food) until you have consulted a doctor.
