Introduction

If jaundice hepatitis is caused by viral hepatitis, it is usually contagious; however, if it is caused by non-viral hepatitis, it is not contagious. If discomfort symptoms occur, it is recommended to seek timely medical treatment at a qualified hospital. To avoid unnecessary harm to the body, it is advised to seek medical attention promptly when symptoms of hepatitis such as jaundice appear, and to undergo diagnosis and treatment under the guidance of a qualified physician.

Generally speaking, jaundice hepatitis can be contagious if it is caused by viral hepatitis; however, if it is caused by non-viral hepatitis, it will not be contagious. If discomfort symptoms appear, it is recommended to seek timely medical treatment at a regular hospital. Detailed analysis is as follows:

When jaundice hepatitis is caused by viral hepatitis, these diseases are usually contagious. The viruses causing hepatitis can spread through specific routes—for example, hepatitis A and E are mainly transmitted via the fecal-oral route, and infection can occur by consuming virus-contaminated food or water. Hepatitis B, C, and D are primarily transmitted through blood, mother-to-child transmission, and sexual contact. Once the virus enters the human body, it attacks the liver, causing liver cell damage and abnormal bilirubin metabolism, leading to jaundice symptoms. During periods of active viral replication, patients have higher viral loads and stronger contagiousness.

If jaundice hepatitis is caused by non-viral hepatitis, it generally will not be transmitted to others. This situation is commonly seen in drug-induced liver injury, alcoholic hepatitis, autoimmune hepatitis, and fatty liver disease. The pathogenesis of these conditions is unrelated to viral infection; instead, liver cell damage results from drug side effects, long-term alcohol consumption, autoimmune disorders, or metabolic abnormalities, which affect the uptake, conversion, and excretion of bilirubin, leading to jaundice. Since there is no transmissible pathogen involved, this type of jaundice hepatitis is not contagious and will not spread to others through daily contact or shared meals.

To avoid unnecessary harm to the body, it is recommended to seek timely medical attention when symptoms of jaundice or hepatitis appear, and to undergo diagnosis and treatment under the guidance of a qualified physician. Additionally, it is important to cultivate healthy lifestyle habits and avoid exposure to potential sources of infection to reduce the risk of contracting viral hepatitis.

What are the symptoms of cholecystitis?

Cholecystitis can be classified as acute or chronic, and symptoms vary depending on the severity of inflammation and whether biliary obstruction is present. Common symptoms include right upper quadrant abdominal pain, nausea, vomiting, fever, indigestion, and mild jaundice. If right upper quadrant pain is accompanied by fever or jaundice, prompt medical evaluation for possible biliary obstruction is necessary. Early intervention, such as acute anti-infective treatment or chronic dietary management, can prevent worsening inflammation or complications.

What are the symptoms of acute suppurative cholangitis?

In general, acute suppurative cholangitis is an emergency condition caused by biliary obstruction combined with bacterial infection. Symptoms include severe pain in the right upper abdomen or epigastrium, chills with high fever, jaundice of the skin and sclera, early signs of shock, nausea, and vomiting. Once these symptoms appear, immediate medical attention is required. Prompt relief of biliary obstruction and effective anti-infective treatment are essential to prevent progression to multi-organ failure.

What causes a bitter taste in the mouth?

Bitter taste in the mouth may be caused by factors such as imbalance of the oral environment, emotional and neurological regulation, gastrointestinal motility disorders, abnormal liver and gallbladder metabolism, or medication effects. It is recommended to maintain a daily water intake of more than 1500 ml, consume moderate amounts of hawthorn and dried tangerine peel to aid digestion, and avoid smoking and limit alcohol consumption. If bitter taste persists for over a week or is accompanied by abdominal pain, jaundice, or significant weight loss, you should visit a gastroenterology or dental clinic for further evaluation, including gastroscopy.
