What are 2 major complications from anorexia nervosa?
- Heart problems, such as mitral valve prolapse, abnormal heart rhythms or heart failure.
- Bone loss (osteoporosis), increasing the risk of fractures.
- Loss of muscle.
- In females, absence of a period.
- In males, decreased testosterone.
- Gastrointestinal problems, such as constipation, bloating or nausea.
What are 3 physiological changes that occur with anorexia nervosa?
Common signs and symptoms include loss of subcutaneous fat tissue, orthostatic hypotension, bradycardia, impaired menstrual function, hair loss, and hypothermia.
What part of the brain is affected by anorexia?
Most fMRI studies performed in patients with anorexia nervosa focused on food, taste, physical appearance and social cognition. Although very different in terms of the study protocol, the most common findings are increased activation of the amygdala and altered activation of the cingulate cortex.
What role does the hypothalamus play in eating?
The hypothalamus via various mechanisms controls appetite and food intake. It is also responsible for the control of hunger and thirst. In the basal hypothalamus there are several nuclei that regulate daily energy homeostasis. These control the appetite.
At what BMI do periods stop?
The greater your BMI (typically in the obesity range over 35), the more likely you are to miss your period. It is even possible to stop bleeding altogether, a condition known as secondary amenorrhea.
How long will it take to get my period back after anorexia?
It may take up to six months for menses to resume after weight has been restored. Persistence of amenorrhea beyond this point may indicate the individual is not truly fully weight restored.
