Step 1: Understanding the symptoms.
Dark yellow urine indicates increased bilirubin in blood, which is excreted through urine. Whitish or clay-colored stools indicate lack of bile pigments reaching the intestine.
Step 2: Cause of itching and pale face.
Accumulation of bile salts in the skin causes itching, while pale face occurs due to liver dysfunction affecting metabolism.
Step 3: Identifying the disease.
All these symptoms are classical signs of jaundice, a condition caused by excess bilirubin in the blood due to liver or bile duct disorders.
Step 4: Eliminating other options.
Constipation and diarrhoea are digestive disorders without bile involvement, and Kwashiorkor is a protein deficiency disease.
