Why is bone marrow iron an important clinical indicator of Bulimia nervosa?

First-line measures should include the use of appropriate standard foods.
General advice includes encouragement to eat small frequent meals and snacks that are high in energy and protein, but address the special requirements of the patient e.g. diabetes or renal impairment.
Small snacks between meals increase nutritional intake e.g. cheese and biscuits, whole-milk yoghurts or toast and peanut butter.
Patients could also use full-fat, instead of low-fat dairy products.
Milk powder may be added to fortify ordinary milk and drinks, tinned soups, mashed potatoes, cereals and puddings (this is not appropriate for infants and young children).
Fortified whole milk or milk shakes between meals should be encouraged. Cream, butter and cheese can also be used to fortify foods such as soups and mashed potatoes.
Energy sources such as sugar, honey, jam and dried fruit can be added to cereals and puddings. Pure fruit juices may also be useful.
Simple measures such as exercise and fresh air can increase appetite.
Eating in the company of others, e.g. at day centres or luncheon clubs, may stimulate patients to eat more.
Alcohol, in moderation, can be an effective appetite stimulant.
Although some drugs, e.g. corticosteroids, can stimulate the appetite, effects are not always immediate or long-lasting and they may cause serious adverse effects. Use is mainly confined to those receiving palliative care and is not usually recommended outside specialist centres. hope this helps
