Loss of Appetite: When to Get Checked and Which Results to Watch

Loss of appetite, medically known as anorexia, refers to a reduced desire to eat. While it can be a temporary issue, persistent loss of appetite may indicate an underlying health problem. Understanding when to seek medical advice and which lab results to monitor can help you manage this symptom effectively.

What is loss of appetite?

Loss of appetite is a condition where you have little or no desire to eat. It can be caused by various factors, including stress, illness, or medication side effects. While occasional changes in appetite are normal, a prolonged lack of interest in food may require medical attention.

Common causes of loss of appetite

Loss of appetite can result from both physical and psychological factors. Common physical causes include gastrointestinal issues, infections, and chronic diseases like cancer or liver disease. Psychological factors can include stress, depression, and anxiety. Certain medications, such as antibiotics and chemotherapy drugs, can also contribute to a decreased appetite.

Lab markers to watch

When experiencing a loss of appetite, several lab markers can help identify potential underlying causes:

• Complete Blood Count (CBC): This test measures different components of your blood, including red and white blood cells. Abnormalities may indicate infections or anemia, which can affect appetite.
• Liver Function Tests (LFTs): These tests assess the health of your liver. Liver issues can lead to a loss of appetite and may require further investigation.
• Thyroid Function Tests: These tests measure levels of thyroid hormones. An overactive or underactive thyroid can influence appetite.
• Electrolyte Panel: This panel checks for imbalances in minerals like sodium and potassium, which can affect appetite and overall health.

When to see a doctor

It's important to consult a healthcare professional if you experience a persistent loss of appetite, especially if accompanied by other symptoms like weight loss, fatigue, or changes in bowel habits. Early diagnosis can help address any underlying conditions and prevent complications.
