When does a doctor order 12 hours fasting cortisol?

Who should get 12 hours fasting cortisol done in Ahmedabad?

NAFLD and hepatitis B both contribute significantly to liver disease in Ahmedabad. Gujarat's high diabetes and obesity rates , independent NAFLD risk factors , combined with rising alcohol consumption in some demographic groups make liver health monitoring particularly important for adults above 35 across Navrangpura, Satellite, Maninagar, and Nikol. 12 hours fasting cortisol is commonly ordered as part of endocrine or adrenal function testing and sometimes during evaluation for Cushing’s or Addison’s syndromes. Doctors may request it when patients have unexplained fatigue, weight change, high blood pressure, mood changes, or muscle weakness. Regular liver testing benefits: regular alcohol drinkers, individuals with BMI above 28, anyone on long-term medication including statins or anti-TB drugs, people with a personal or family history of hepatitis B or C, those with type 2 diabetes or metabolic syndrome, and all adults above 40 in annual preventive panels. In Ahmedabad, residents of Ambawadi, Vastrapur, and similar areas with sedentary lifestyles and calorie-dense diets face particularly elevated metabolic liver risk.

What conditions can 12 hours fasting cortisol help diagnose?

Very high ALT and AST (10–50× normal) with normal ALP suggests acute hepatocellular injury , viral hepatitis, drug toxicity, or ischaemia. Predominantly elevated ALP and GGT with modest transaminases suggests bile duct obstruction or primary biliary cholangitis. An AST:ALT ratio above 2 suggests alcoholic hepatitis. Persistently low albumin with elevated bilirubin indicates advanced cirrhosis.

What do 12 hours fasting cortisol results mean?

Mildly elevated ALT or AST (2–3× normal): fatty liver, obesity, or medication effect , often reversible. Moderately elevated (3–10×): active viral hepatitis or drug toxicity , requires urgent investigation. Severely elevated (>10×): acute liver injury , a medical emergency. High bilirubin: liver processing failure, bile duct obstruction, or haemolysis. Low albumin: significant loss of liver synthetic function, seen in advanced cirrhosis or malnutrition.

How often should 12 hours fasting cortisol be repeated?

Adults with no liver risk factors and a previously normal result: annually. Patients with NAFLD or treated hepatitis: every 6 months. Patients on hepatotoxic medication: baseline before starting, then at 1 month, 3 months, and every 6 months during treatment.
