Acute pancreatitis is a serious condition that causes severe abdominal pain and needs strict medical care, while increased liver echotexture and a size around 13.2 cm often suggest Fatty liver disease. You should follow a strict low-fat diet, avoid alcohol completely, stay well hydrated, and take only doctor-prescribed medicines. Regular follow-up with blood tests and scans is important to monitor recovery, and if you have severe pain, vomiting, or fever, seek immediate medical attention.
