If anorexia nervosa progresses, it can cause a number of serious health problems. In extreme cases, it can even lead to death.
Physically, anorexia can cause multiple organ failure, electrolyte imbalance, severe dehydration, multiple nutrient deficiencies, and stunted growth. It can also cause amenorrhea (absence of menstrual periods) in women, as well as bone loss, anemia, and damage to the heart, kidneys, and liver. It can also cause an irregular heartbeat, low blood pressure, and an increased risk of suicide or self-harm.
Mentally, anorexia can cause anxiety, depression, and obsessive-compulsive behavior. It can also lead to social isolation and difficulty forming relationships. Long-term anorexia can also cause cognitive impairment, including difficulty concentrating, memory loss, and poor decision making.
If left untreated, anorexia can cause irreversible damage and even death. Therefore, it is important to seek help as soon as possible if you or someone you know is suffering from anorexia. Treatment typically involves a combination of psychotherapy, nutrition education, and medication. With early intervention and appropriate treatment, it is possible to make a full recovery from anorexia.
