Hepatitis B is clinically differentiated between acute and chronic. Both acute and chronic can present with and without jaundice. In other words, both acute and chronic hepatitis B may show symptoms of yellowing of the eyes and skin. Some people are afraid when they see a patient with hepatitis B who is yellow all over, worrying that the more yellow the color, the more infectious it is, but this is actually unfounded. Generally speaking, the shade of jaundice is only related to the severity of the disease, and is not directly related to infectiousness. The same patient with hepatitis B can behave very differently. Acute jaundice can be characterized by fear of cold, fever, general weakness, loss of appetite, nausea, vomiting, especially aversion to greasy food, distention and stuffiness in the upper abdomen, yellow urine like strong tea, and thin or constipated stools. In the early stage, some patients show inflammation of the upper respiratory tract, similar to a cold. Some patients may have joint pain, which is often mistaken for rheumatism. A few people also present with severe abdominal pain and are mistaken for an acute abdomen. In a few cases, hives may appear. Immediately afterwards, the patient’s white eyes, skin and mucous membranes become yellow and the digestive symptoms further worsen. In the recovery period, the jaundice gradually subsides and the symptoms gradually disappear. In the non-jaundiced form of hepatitis B, the symptoms of yellowing of the white eyes, skin and mucous membranes do not occur, but symptoms such as anorexia, anorexia for oil and grease, fatigue and weakness, and upper abdominal discomfort may be present in varying degrees of severity.
