- The cardiovascular system (heart attack; elevated cholesterol/atherosclerosis; abnormal heart rhythms;
hypertension; peripheral vascular disease; stroke)
- the musculoskeletal
system (osteoarthritis in the

- Psychological Complications
- Body shape discontent
- Consequently may lead to strain on their intimate and romantic relationships
- Further leads to depression, isolation, anxiety, suicidal ideas, withdrawn from society and anhedonia
- Investigations include
- Complete blood count
- Liver enzyme and liver function tests
- Tests for chronic viral hepatitis (hepatitis A, hepatitis C and others)
- Celiac disease screening
- Fasting blood sugar
- Hemoglobin A1C, which shows how stable your blood sugar is
- Lipid profile, which measures blood
fats, such as cholesterol and
triglycerides

- Management
- Psychological Treatment

- Relationship between food intake and energy expenditure
- “Energy balance” is the relationship between “energy in”
(food calories taken into the body through food and drink)
and “energy out” (calories being used in the body for our
daily energy requirements).
- Imbalances lead to
- Food intake
- Physiology of food intake and satiety
- Feeding center:
- Lateral nuclei of the
hypothalamus and
Dorso-medial nucleus
(DMN)
- Satiety center:
- Ventro-medial nuclei of the
hypothalamus (VNH) and
Para-ventricular nucleus (PVN)
- Hormonal control
- Liver anatomy
- 2 lobes
- Wedge-shaped & resembles 4 sided
pyramid laid on one side with its apex
directed to the left.
- found in right hypochondrium,
greater part of the epigastrium
and extends into the left
hypochondriurn up to the left
lateral vertical line.
- Blood supply of the liver
- Liver histology
- Lobule: It has a roughly hexagonal
shape with : Central vein at its
center
- Portal Triads at each corner consist of: 1. Hepatic Arteriole 2. Portal Venule 3.
Bile Ductule 4. Lympahatic vessels
- Liver
- liver is the main organ of metabolism and
energy production; its other main functions
include:
- Bile production
- Storage of iron, vitamins and trace elements
- conversion of waste products for excretion by the kidneys
- detoxification
- Metabolism of carbohydrates, fat, and proteins
- Three stages of FA synthesis:
- . Transport of acetyl COA into cytosol
- Carboxylation of acetyl COA
- Assembly of FA chain ( Elongation)
- Alcohol metabolism
