Malnutrition: MedlinePlus

P Food provides the energy and nutrients you need to be healthy. If you don't get enough nutrients -- including proteins, carbohydrates, fats, vitamins, and minerals - you may suffer from malnutrition.
P Causes of malnutrition include:
- Lack of specific nutrients in your diet. Even the lack of one vitamin can lead to malnutrition.
- An unbalanced diet
- Certain medical problems, such as malabsorption syndromes and cancers
P Symptoms may include fatigue, dizziness, and weight loss. Or, you may have no symptoms. To diagnose the cause of the problem, your doctor may do blood tests and a nutritional assessment. Treatment may include replacing the missing nutrients and treating the underlying cause.
