Appetite - decreased

Alternative Names:

Loss of appetite; Decreased appetite

Home Care:

Protein and calorie intake can be increased by intake of high-calorie, nutritious snacks or several small meals during the day. Liquid protein drinks may be helpful. Family members should try to supply favorite foods to help stimulate the person's appetite.

A 24-hour diet history should be recorded each day. If an anorexic person consistently exaggerates food intake (a common occurrence in anorexia nervosa), strict calorie and nutrient counts should be maintained by someone else.

For loss of appetite caused by taking medications, talk to your health care provider about adjusting the dosage or changing drugs. NEVER CHANGE MEDICATIONS WITHOUT FIRST CONSULTING YOUR HEALTH CARE PROVIDER.

Call your health care provider if:

Call your health care provider if involuntary weight loss exceeds 7% of total body weight within a month.

Note: To calculate percent weight lost, divide pounds lost by the previous weight and multiply times 100. For example, a person weighing 125 pounds loses 10 pounds:

10 divided by 125 = 0.08
0.08 times 100 = 8%

What to expect at your health care provider's office:

The diet and medical history will be obtained and a physical examination performed, including height and weight.

Medical history questions documenting loss of appetite in detail may include:

Quality
- Is it severe, or mild?
- How much weight has been lost?
Time pattern
- Is loss of appetite a new symptom?
- If so, did it start after an upsetting event, such as the death of a family member?
What other symptoms are also present?

Diagnostic tests that may be performed include:

Barium enema, sigmoidoscopy, or colonoscopy (if colon cancer is suspected)
Liver function tests
Kidney function tests
Thyroid function tests
Abdominal ultrasound (if a specific abdominal cause is suspected)
Upper GI series
Pregnancy test
Urine drug screening
HIV test

In severe malnutrition, supplemental intravenous nutritional support may be ordered. Some patients must be hospitalized for nutritional support.
