Which vital sign is often low in individuals with anorexia?

Individuals with anorexia often experience a range of physiological changes due to prolonged malnutrition and energy deficiency. Each of the vital signs listed can be affected by this condition, leading to them being lower than normal.

Heart rate typically decreases in individuals with anorexia, a condition known as bradycardia, which occurs as the body tries to conserve energy. Additionally, malnourishment can lead to changes in heart function and hormonal balance, further contributing to this decreased heart rate.

Respiratory rate may also be lower than expected. In cases of severe anorexia, the body may enter a state of metabolic adaptation, where it conserves energy, which can include a slowing of respiratory function.

Blood pressure often shows a tendency towards hypotension in individuals with anorexia. Low body weight and decreased blood volume due to inadequate nutritional intake can lead to reduced blood pressure levels.

Given the impacts of anorexia on these vital signs, it is accurate to say that all three can be low in individuals suffering from this eating disorder. Therefore, the choice reflecting that all of these vital signs are often low is supported by the physiological changes that occur in anorexia.
