Why does anorexia cause low temperature?
The body also drops its core temperature which can make patients feel very cold, especially in their hands and toes; this is aggravated by the decrease in body fat and thus insulation that goes along with malnutrition.

Can anorexics get hypothermia?
Persons with chronic undernutrition experience a flattening of the normal diurnal temperature curve with eventual onset of hypothermia. In recovery, the flattening persists but the hypothermia warms up. Thus, persons with anorexia who are refeeding often complain of being hot and sweaty at night.
What are the symptoms of refeeding syndrome?
- Difficulty breathing.
- High blood pressure.
- Irregular heartbeat.
How low can your temperature go?

Why do I go cold when I’m hungry?

Why do anorexics get lanugo?

What does a low body temperature indicate?
Why is my body temperature low? Studies show that core body temperature decreases with age. Hypothyroidism, or an underactive thyroid, can also slow down metabolism, which can lead to a drop in body temperature. If your core body temperature dips down to 95 F (35 C) or lower, that’s considered hypothermia.
Is it OK if my temperature is 96?
Call a healthcare professional if your temperature is 96°F (35.55°C) and you feel sick. You can describe your symptoms over the phone. They may offer a diagnosis or ask you to make an office visit.
