Dear Dave,
Does your father suffer from Hypertension or any other cardiac ailment too? Has his liver function test been taken? Whether it is due to Helicobacter pylori or decrease in the function of the liver causing this “swelling” in the abdomen, Homeopathic Medicine has good remedies to relieve him of the same.
Medicines like Nux vom, Lycopodium, Cardus marianus will improve his symptoms.
