People with hepatitis B can drink coffee in most cases, but in some special cases they should be careful to drink less coffee, or even no coffee. If hepatitis B has caused liver damage, there is an increase in glutamic aminotransferase and glutamic oxalacetic aminotransferase, which is likely to cause the aminotransferase to continue to rise if good rest is not taken at this time. If you don’t take rest during the treatment, it will cause the transaminases to drop poorly. Drinking coffee may affect your sleep, so you should try to drink less coffee at this time, and you should pay attention to rest, avoid exercise, and avoid exertion. Drinking coffee will mainly lead to poor sleep, but there are some people who drink coffee regularly, which does not lead to sleep disorders, and this group of people can drink coffee in moderation. The amount of coffee should not be too large, drinking more coffee will also increase the intake of fat or other calories, which does not have a particularly beneficial effect on the patient. However, as long as coffee does not cause sleep disorders, it will not be harmful to the condition of hepatitis B patients.
