Recognizing Common Symptoms

Understand what common symptoms mean. Common symptoms typically occur one to four months after Hepatitis B infection. In addition, keep in mind that having just one common symptom, such as fatigue or a fever, does not indicate you have Hepatitis B. If, however, you believe you may have been exposed to Hepatitis B and you are displaying common signs and symptoms of the disease, you should talk to your doctor about getting tested.^{[2]

- If you think you were exposed to Hepatitis B within the past 24 hours, a preventative treatment may reduce your risk of infection.
- If you believe you were exposed to Hepatitis B but do not have symptoms, you should still talk to your doctor, as those with chronic Hepatitis Be remain symptomless for as long as 20 or 30 years.^{[3]

Recognizing Secondary Symptoms

^{[22]
X
Research source} As a result of diarrhea or vomiting, you may become dehydrated. An inability to urinate or a constant thirsty feeling could indicate your are dehydrated. Try to drink as much water as possible to combat dehydration.
If you no longer feel as hungry as you used to, you might have Hepatitis B. The loss of appetite could be a result of abdominal pain, but it might be independent of it, too. Monitor your eating habits and your weight closely in order to determine whether you're eating less than before and, as a result, losing weight.
^{[23]

Research source} When you're in constant pain due to abdominal swelling or tenderness and feel badly fatigued all the time, you'll probably become irritable. You may have less patience with friends or loved ones and become easily frustrated by situations which, before the onset of the primary Hepatitis B symptoms, caused you no stress. Listen to your friends and family to determine if you're becoming irritable, and monitor your own behavior if you think your demeanor is changing.

Minimizing Hepatitis B Symptoms

If you think you have Hepatitis B, you should see your doctor for testing. Acute Hepatitis B cannot be treated with medication. If you have Hepatitis B, however, you and your doctor can come up with a plan to treat and minimize symptoms. Though not appropriate for everyone, the following medications may be used to treat Hepatitis B: entecavir, interferons, and lamivudine.

Stay hydrated.^{[24]

Research source} Drink plenty of water to replenish water lost through vomiting or diarrhea. Fruit juice, iced tea, and sports drinks are also good for replenishing your body's water content. Soups and smoothies are good options during meal times.
- Daily fluid intake (including fluids found in foods and all beverages, not just water) for women should be 11 8-oz glasses (2.7 liters) and 15 cups (3.7 liters) for men.

Eat a healthy diet. Eat a satisfying breakfast, but don't eat too much. Make fruits and whole grains the foundation of your healthy breakfast. Later in the day, eat light meals consisting primarily of fruits, vegetables, whole grains, and small portions of lean protein. Avoid processed foods heavy in salt, sugar, and fat.^{[27]
