p e n d a h u lu a n• Diagnosis penyakit Hepato-Bilier sekitar 50 %
sudah dapat ditegakkan berdasarkan anamnesis yang akurat, dan pemeriksaan fisik.
• Pemeriksaan laboratorium , dan Pemeriksaan penunjang lainnya dapat membantu diagnosis penyakit hepatobiler. Menjadi lebih jelas.
• Pemeriksaan biopsi hati merupakan "gold standard" untuk mengevaluasi kelainan di hati .
• Pemeriksaan biopsi hati sedikit penggunaannya untuk diagnosis.

hepatocytes.• Salts as above can affect the osmotic
concentration of the blood and are controlled for the same reason.
• Amino acids as with sugar can affect the osmotic concentration of blood.
• Vitamins & Minerals diet is crucial for enzyme function, skeletal development, vision along with a variety of other essential functions.

Some Major Features of Liver Disease Feature Description
Jaundice A yellowish discoloration of the skin and whites of the eyes
Hepatomegaly Liver enlargementAscites Fluid in the abdominal cavityHepatic encephalopathy Confusion caused by deterioration of brain function due
to buildup of toxic substances in the blood
Gastrointestinal bleeding Bleeding from large, tortuous veins (varices) in the esophagus and stomach

Hormonal abnormalities High levels of insulin Some Trade Names HUMULINNOVOLINbut a poor response to it, leading to high blood sugar levels Cessation of menstrual periods and decreased fertility in women Erectile dysfunction and feminization in men

* Muehrcke’s nails: white bands separated by normal appearing nails; Terry’s nail: proximal part two third of the nail is white while the distal third is normal color. Both of these are nonspecific and are tought to result from periods of hypoalbuminemia.** Cruveilhier Baumgarten’s sign: venous hum heard best over the epigastrium due to portosystemic collaterals between the portal vein and umbilical vein.
