Overview
Key Facts & Overview
Definition & Terminology
Formal Definition
Anatomy & Body Systems
Primary Systems
Thyroid Gland: Regulates metabolism. An overactive thyroid (hyperthyroidism) can cause rapid weight loss despite increased appetite.
Pancreas: Produces digestive enzymes and hormones. Pancreatic insufficiency affects nutrient absorption; diabetes affects glucose metabolism.
Adrenal Glands: Produce hormones that affect metabolism and stress response. Addison's disease can cause weight loss.
Digestive System: The entire GI tract from mouth to rectum is involved in nutrient digestion and absorption.
Supporting Systems
Hormonal System: Multiple hormones regulate appetite, metabolism, and fat distribution.
Nervous System: Controls appetite and satiety signals; gut-brain axis affects eating behaviors.
Immune System: Chronic inflammation can increase metabolic rate and decrease appetite.
Types & Classifications
By Mechanism
Decreased Intake: Due to reduced appetite, swallowing difficulties, or psychological factors
Increased Requirements: Due to hypermetabolic conditions, hyperthyroidism, or chronic illness
Malabsorption: Due to digestive conditions affecting nutrient absorption
Combined Mechanism: Most cases involve multiple factors
By Pattern
Rapid Weight Loss: More than 2 pounds (1 kg) per week
Gradual Weight Loss: Progressive over months
Cyclic Weight Loss: Alternating weight loss and regain
By Underlying Cause
Organic: Due to physical illness (cancer, thyroid, diabetes)
Psychogenic: Due to mental health conditions (depression, anxiety, eating disorders)
Iatrogenic: Due to medications or medical treatments
Causes & Root Factors
Primary Causes
Hyperthyroidism: An overactive thyroid gland increases metabolism, causing rapid weight loss, heat intolerance, tremors, and rapid heartbeat.
Diabetes Mellitus: Especially Type 1 diabetes, where the body cannot use glucose properly, leading to weight loss despite increased appetite.
Gastrointestinal Malabsorption: Conditions affecting nutrient absorption in the intestines—celiac disease, pancreatic insufficiency, Crohn's disease, small intestinal bacterial overgrowth (SIBO).
Chronic Infections: Tuberculosis, HIV, parasitic infections can cause significant weight loss.
Cancer: Many cancers, particularly gastrointestinal cancers, cause weight loss through multiple mechanisms.
Secondary Causes
Depression and Anxiety: Mental health conditions commonly affect appetite and eating behaviors.
Dementia: In older adults, cognitive decline can lead to forgetting to eat or difficulty with meal preparation.
Medications: Many medications cause weight loss as a side effect, including some chemotherapy drugs, stimulants, and certain antidepressants.
Chronic Kidney Disease: Affects metabolism and appetite.
Heart Failure: Cachexia can develop in advanced heart failure.
Lifestyle Factors
Poor Diet: Inadequate caloric or nutritional intake
Substance Use: Alcohol and drug abuse can suppress appetite and nutrition
Dental Problems: Difficulty chewing can limit food intake
Risk Factors
Non-Modifiable Factors
- Age: Older adults (65+) at higher risk
- Family History: Certain genetic conditions
- Previous Illness History: Previous cancer or chronic disease
Modifiable Factors
- Smoking Cessation: Can initially cause weight gain but long-term health benefits outweigh this
- Alcohol Use: Excessive alcohol affects nutrition
- Stress Levels: Chronic stress affects appetite and metabolism
- Physical Activity: Both too much and too little can affect weight
