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.
- Graves' Disease
A condition involving an overactive thyroid gland. It's a disorder where the immune system mistakenly attacks the thyroid gland and causes an overproduction of thyroid hormone. It is more common in women than men. Some symptoms include anxiety, weight loss, tremors, changes in menstrual cycles, increase in bowel movements, fatigue, and palpitations.
- Bone Tumor
- Functional Dyspepsia
- Gastric Cancer
- Multiple Myeloma (MM)
- Diabetes Mellitus
- Lung 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.
