How does Anorexia causing intolerance to the cold?

Anorexia nervosa can lead to intolerance to cold because:

- Starving: Anorexia causes extreme starvation, due to the body's reduced ability to maintain healthy body temperature.

- Reduced body fat: Body fat acts as an insulator, helping the body retain heat. When a person with anorexia has very low body fat, their ability to stay warm is severely compromised.

- Slower metabolic rate: Anorexia causes a slower metabolism, which means the body produces less heat. This further contributes to the feeling of coldness.

- Poor blood circulation: Anorexia can cause poor blood circulation, especially to the extremities like the hands and feet. This makes it harder for the body to deliver warmth to these areas.

- Changes in hormone levels: Anorexia can alter the levels of certain hormones, including estrogen, progesterone, and testosterone. These hormones play a role in regulating body temperature, and their disruption can lead to increased sensitivity to cold.

- Low thyroid function: Anorexia can lead to low thyroid function (hypothyroidism), which can cause a range of symptoms, including cold intolerance.
