There are many problems that can result from having anorexia nervosa. Most of the side effects result from eating far less food than the body needs to maintain itself. The more serious consequences of malnutrition and weight loss include loss of normal menstrual cycles, lower levels of estrogen and weakened bones, and loss of brain tissue and muscle, including the heart muscle. Other side effects include decreased energy, low blood pressure, feeling dizzy and faint, feeling cold much of the time, constipation, decreased ability to concentrate urine resulting in more frequent urination, growth of fine hair on the arms and trunk, fatigue, lack of interest in things including sex, and depression. If the individual also vomits or uses laxatives or diuretics (water pills) in an attempt to control weight, severe disturbances in electrolytes (salt and minerals in the blood) can lead to dangerously abnormal heart rhythms.
