The biological approach believes behavior to be as a consequence of our genetics and physiology. It is the only approach in psychology that examines thoughts, feelings, and behaviors from a biological and thus physical point of view. Therefore, all that is psychological is first physiological.

Is there a genetic component to anorexia?
Although thought of as a psychological problem, the eating disorder anorexia nervosa often runs in families, suggesting that it has a genetic component. Now researchers have found two genes that help determine the risk of acquiring the disease.

About half of all anorexics have low white-blood-cell counts, and about a third are anemic. Both conditions can lower the immune system’s resistance to disease, leaving a person vulnerable to infections.
What biological factors affect mental health?

What biological factors affect behavior?
Abstract. A growing body of evidence suggests that biological factors such as genes, hormone levels, brain structure, and brain functioning influence the development and trajectory of conduct problems in youth.
Which is most responsible for causing eating disorders?
What causes eating disorders? The exact cause of eating disorders is unknown. However, many doctors believe that a combination of genetic, physical, social, and psychological factors may contribute to the development of an eating disorder. For instance, research suggests that serotonin may influence eating behaviors.

- body dissatisfaction and frequent thoughts about an “ideal” appearance.

What part of the brain is responsible for anorexia?
The brain region known as the right insula also seems to be altered in people with anorexia. That bit of brain helps to process taste sensations, but it’s also involved in interoception, the ability to sense one’s own bodily signals. Those skewed body signals are the subjects of Zucker’s research at Duke.
What neurotransmitters cause anorexia?
In anorexia, the leading hypothesis is that the disorder is associated with an over-production of dopamine, leading to anxiety (Bailer et al., 2012a), harm avoidance (Bailer et al., 2012b), hyperactivity and the ability to go without pleasurable things like food (Kontis & Theochari, 2012).
What are 5 physical effects of anorexia?
Medical complications resulting from semistarvation and overexercising affect virtually every organ system. Common signs and symptoms include loss of subcutaneous fat tissue, orthostatic hypotension, bradycardia, impaired menstrual function, hair loss, and hypothermia.
Is anorexia a mental or physical?

- Decrease in white blood cells.
- Amenorrhea (absence of menstruation in females).
