Overview

Unexplained weight loss is a significant symptom in mesothelioma patients, often indicating advanced disease. Patients may lose 10 or more pounds without trying, due to cancer-induced metabolic changes and reduced appetite.

Prevalence: 30% of mesothelioma patients at diagnosis

Mesothelioma Types Associated With Weight Loss

  • All mesothelioma types

What Causes Weight Loss in Mesothelioma?

→ Cancer cachexia (wasting syndrome)
→ Loss of appetite
→ Difficulty eating due to abdominal pressure
→ Increased metabolic demands from cancer

When to See a Doctor

Seek medical attention if you have a history of asbestos exposure and experience:

  • Losing more than 5% of body weight without trying
  • Loss of appetite lasting more than 2 weeks
  • Feeling full quickly when eating
  • Clothes fitting loosely

Connection to Asbestos Exposure

Weight Loss in the context of mesothelioma is directly linked to prior asbestos exposure. The latency period between asbestos exposure and symptom development averages 20-50 years. If you worked in industries with asbestos exposure (such as construction, shipbuilding, automotive repair, or military service) and experience weight loss, inform your doctor about your exposure history.

Early detection of mesothelioma significantly improves treatment options and outcomes. Patients diagnosed at earlier stages have access to surgical options and multimodal treatments that can extend survival.

Concerned About Your Symptoms?

If you have a history of asbestos exposure and are experiencing weight loss or other symptoms, early evaluation is important.
