Colon cancer screening aims to detect early colorectal neoplasia and precancerous lesions in asymptomatic individuals to reduce cancer-related morbidity and mortality. This involves risk stratification and appropriate use of screening tools such as fecal occult blood testing or colonoscopy, with timely follow-up of abnormal results.
Chronic hepatitis B can lead to progressive liver disease, cirrhosis and hepatocellular carcinoma. Management focuses on regular monitoring of viral activity and liver function, risk stratification and initiation of antiviral therapy when indicated to reduce disease progression and complications.
Constipation in children commonly presents with infrequent, hard stools and may be associated with withholding behavior or painful defecation. A structured approach includes excluding red flags, education, behavioral strategies and appropriate use of pharmacological therapy to achieve regular, normal bowel habits.
Liver function test (LFT) abnormalities may reflect hepatocellular injury, cholestasis or disturbance in synthetic function. Interpretation requires pattern recognition alongside clinical context, with further evaluation guided by underlying risk factors and associated findings.
Helicobacter pylori (H. pylori) infection is associated with chronic gastritis, peptic ulcer disease and an increased risk of gastric malignancy. Management involves appropriate testing and eradication therapy using combination regimens tailored to local resistance patterns to improve outcomes.
Gastroesophageal reflux disease (GERD) presents with symptoms such as heartburn and regurgitation due to reflux of gastric contents into the oesophagus. Management is guided by symptom severity and response to therapy, focusing on lifestyle measures, acid suppression with pharmacological therapy and further evaluation when alarm features are present.
