Differential Diagnosis for 46-year-old Male with Abdominal Bloating and Constipation

Single Most Likely Diagnosis

  • Non-Alcoholic Fatty Liver Disease (NAFLD): The patient has fatty liver, elevated LDL cholesterol, and triglycerides, which are common findings in NAFLD. The normal GGt and lipase also support this diagnosis, as NAFLD is often associated with mild elevations in liver enzymes.

Other Likely Diagnoses

  • Hypothyroidism: The patient's symptoms of abdominal bloating and constipation, along with the elevated alkaline phosphatase and low vitamin D levels, could be indicative of hypothyroidism.
  • Insulin Resistance: The patient's elevated triglycerides, LDL cholesterol, and presence of fatty liver suggest insulin resistance, which is a precursor to type 2 diabetes.
  • Vitamin D Deficiency: The patient's low vitamin D levels could be contributing to their symptoms, and vitamin D deficiency is common in patients with fatty liver disease.

Do Not Miss Diagnoses

  • Hepatitis B: Although the patient's Hep B Surf AB is non-reactive, the positive Hepatitis B Core Antibody (IgM) and total (IgG+IgM) suggest a possible hepatitis B infection. This diagnosis is crucial to rule out due to the potential for severe liver damage and transmission to others.
  • Thyroid Cancer: The small mass on the posterior neck could be a thyroid nodule, which warrants further investigation to rule out thyroid cancer.

Rare Diagnoses

  • Celiac Disease: The patient's abdominal bloating and constipation could be indicative of celiac disease, although this is less likely given the absence of other typical symptoms such as diarrhea and weight loss.
  • Primary Biliary Cholangitis: The patient's elevated alkaline phosphatase and presence of fatty liver could be suggestive of primary biliary cholangitis, although this is a rare condition and other diagnoses are more likely.
