People suffering from anorexia wear layers of clothes to hide their weak figures and to prevent the cold. Excessive weight loss reduces the amount of fat in the body that serves as insulation against the cold weather.
Anorexic people often go through phases of hunger that can lead to serious problems. The body loses potassium and sodium during fasting that causes them to be weak. Also, low levels of potassium can bring irregular heartbeat and even heart attacks.
Informally, people with anorexia don’t like other people who are obese or overweight. They think that these people are not self-controlled because they cannot manage their weight.
