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 and dystrophic mesenteric adipocytes direct 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
Serous fat atrophy
- Fat atrophy redirects to here
General
Associations:[1]
- Acute febrile states.
- AIDS.
- Alcoholism.
- Anorexia nervosa.
- Cachexia.
- Carcinomas.
- Chronic heart failure.
- Lymphoma.
Gross
Features:[1]
- Soft brown/myxoid material replaces fat.
Microscopic
Features - serous fat atrophy:
- Globular cells ~3-4x the size of a RBC (24-32 micrometers) with:
- Clear cytoplasm.
- One small peripheral nucleus without a nucleolus.
