Starvation is defined as deprivation of food for a lengthy period. Generally, it is due to lack of food, inability to eat or lack of desire to eat. It may include people that can eat but cannot absorb the nutrients in their food.
This article covers serous fat atrophy as it is classically seen in starvation. Cachexia directs here.
Starvation
Causes of starvation
- Psychiatric:
- Dementia.
- Anorexia nervosa.
- Disorder with delusions, e.g. schizophrenia, bipolar affective disorder - belief one is being poisoned.
- Organic disease:
- Malignancy, e.g. esophageal carcinoma.
- Causes of malabsorption.
- Vomiting.
- Other:
- Poverty.
- Young age (cannot feed themself).
- Disability/trauma - person falls and cannot get up, help not available.
Gross findings of starvation
Features:
- Very low body mass index (BMI).
- Membranous-appearing (thin) omentum.
- Soft brown/myxoid material replaces fat (serous fat atrophy).
Associated conditions
