Information for Patients


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.

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

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.

Vitamin D

Also called: Cholecalciferol, Ergocalciferol

Vitamins are substances that your body needs to grow and develop normally. Vitamin D helps your body absorb calcium. Calcium is one of the main building blocks of bone. A lack of vitamin D can lead to bone diseases such as osteoporosis or rickets. Vitamin D also has a role in your nerve, muscle, and immune systems.

You can get vitamin D in three ways: through your skin, from your diet, and from supplements. Your body forms vitamin D naturally after exposure to sunlight. However, too much sun exposure can lead to skin aging and skin cancer. So many people try to get their vitamin D from other sources.

Vitamin D-rich foods include egg yolks, saltwater fish, and liver. Some other foods, like milk and cereal, often have added vitamin D.

You can also take vitamin D supplements. Check with your health care provider to see how much you should take. People who might need extra vitamin D include

  • Seniors
  • Breastfed infants
  • People with dark skin
  • People with certain conditions, such as liver diseases, cystic fibrosis and Crohn's disease
  • People who are obese or have had gastric bypass surgery
