Unintentional weight loss
Possible Causes
Generally, Unintentional weight loss can be related to:
- Pleural Mesothelioma
Pleural mesothelioma is a rare cancer that occurs in the thin tissue layer around the lungs. It's more common in people over 50 years old. The most likely cause is long-term exposure to a mineral called "asbestos".
- Pancreatic Cancer
Pancreatic cancers most commonly arise in the cells that line the ducts of the pancreas. Risk factors include heavy alcohol use resulting in chronic pancreatitis, diabetes, obesity, and smoking, and a family history of pancreatic cancer as well as some inherited syndromes. There are usually no symptoms when the tumor is small but later symptoms include yellowing of the skin (jaundice), mid-back pain, abdominal pain or discomfort, weight loss and fatigue.
- Systemic Lupus Erythematosus (SLE)
An autoimmune disease caused by the body's immune system attacking organs and cells. The exact cause is unclear, but risk factors include being female, childbearing age, and heredity. SLE may involve nearly every organ system in the body with a wide range of potential symptoms that often wax and wane over time.
- Non-Hodgkin Lymphoma
- Colon Cancer
- Bone Tumor
- Functional Dyspepsia
- Graves' Disease
- Breast Cancer
Related serious diseases
Sometimes, Unintentional weight loss may be related to these serious diseases:
- Dehydration
Dehydration happens when you lose more fluid than you consume, leaving your body without enough water. Common causes include inadequate intake, diarrhea, vomiting, and fever. Dehydration can also cause serious complications like seizures, urinary and kidney problems.
