The objectives of treating chronic hepatitis infection is to control the level of inflammation in the liver and to prevent complications such as liver hardening and liver cancer from developing. I would like to stress that not all hepatitis B patients require treatment. However, those who need oral anti-viral treatment usually have to take the treatment for a long period of time. At the moment, the only other option with a definitive treatment period is through an injectable form of medicine known as interferon.
I was diagnosed with Irritable Bowel Syndrome, but started having having pounding/ throbbing sensations in my abdomen at night, while sleeping. What is the best treatment for this?
Irritable bowel syndrome is a common condition experienced by many young adults and teenagers with typical abdominal pain or cramps associated with a change in the stool frequency or stool consistency. These symptoms are frequently precipitated by exams, deadlines and other forms of stress. Interestingly, throbbing / pounding sensation in the abdomen happening at night is not a usual complain I have come across based on my experience in managing IBS patients.
The attached test results and DNA level are consistent with a patient in an immune tolerant phase of chronic hepatitis B infection. This phase indicates an active viral replication without an immune reaction against the virus. A person in such a phase with high viral counts is highly infectious although relatively well most times. Treatment decisions usually rely on factors such as the person's age, evidence of liver scarring (fibrosis) or hardening (cirrhosis), liver enzyme fluctuations, HBe antigen status as well as family history of liver cancer.
