Unexplained weight loss can be a cause for concern, as it may indicate an underlying health issue. While some weight loss can be attributed to lifestyle changes, such as diet and exercise, sudden and unintentional weight loss without any apparent reason should not be ignored.

So, in this article, we will explore the possible causes of unexplained weight loss and provide guidance on when to seek medical attention.

What Causes Unintentional Weight Loss?

1. Underlying medical conditions

Unexplained weight loss can be a symptom of various medical conditions, including the following [1]:

- Thyroid problems: Hyperthyroidism, an overactive thyroid, can lead to rapid weight loss.

- Diabetes: Uncontrolled diabetes can cause weight loss due to the body's inability to properly make use of glucose.

- Cancer: Certain types of cancer, such as pancreatic or lung cancer, can cause unexplained weight loss.

- Chronic infections: Tuberculosis, HIV/AIDS, and other chronic infections can lead to weight loss.

2. Gastrointestinal disorders

Several gastrointestinal disorders can contribute to unexplained weight loss, such as:

- Celiac disease: An autoimmune disorder triggered by gluten consumption, which can lead to malabsorption and weight loss [2].

- Inflammatory bowel disease (IBD): Conditions like Crohn's disease and ulcerative colitis can cause weight loss due to decreased nutrient absorption.

- Peptic ulcers: These painful sores in the stomach or small intestine can lead to weight loss due to reduced appetite and nutrient absorption.

3. Mental health conditions

Some mental health conditions can be associated with unexplained weight loss, including:

- Depression: Changes in appetite and weight loss are common symptoms of depression.

- Eating disorders: Conditions like anorexia nervosa and bulimia can cause significant weight loss due to restrictive eating habits and binge eating [3].

4. Medications and treatments

Certain medications and treatments may cause unexplained weight loss, such as:

- Chemotherapy: Cancer treatments can lead to weight loss due to the side effects on the digestive system.

- Antidepressants: Some antidepressant medications may cause weight loss as a side effect.

- Stimulants: Medications used for attention deficit hyperactivity disorder (ADHD) can suppress appetite, leading to weight loss [4].

When to Seek Medical Attention

While occasional fluctuations in weight are normal, rapid and unexplained weight loss should be evaluated by a healthcare professional. Consult a doctor if you experience any of the following [5][6]:

- Losing more than 5 per cent of your body weight in a month without trying.

- Persistent loss of appetite and unintentional weight loss.

- Other concerning symptoms accompany weight loss, such as fatigue, pain, or changes in bowel habits.
