Hepatitis C is just one in a family of viruses that invades the liver, leading to complications such as inflammation, cirrhosis and, in some cases, liver failure or cancer. Known for its slow, nearly silent progression, the virus can go undetected for years before symptoms start to surface. The most common—and usually most troubling—of those is fatigue.
Many reasons for hep C fatigue
A number of factors contribute to hep C’s debilitating fatigue. Though research is conflicting, some experts believe that the virus itself brings on fatigue. In the early, acute stage of the illness, some people have flu-like symptoms caused by the attack on the liver and the body’s response to the virus. Many people have no symptoms for many years after that, yet up to half experience extreme tiredness at times.
Another possibility is psychological: People may become depressed when they learn they have a serious, chronic illness. That stress and sadness could contribute to the overall feeling of weakness and exhaustion. Drug or alcohol abuse, both common among people with hep C, could also play a role.
Without treatment, the infection eventually also causes cirrhosis (scarring) of the liver, and fatigue is a common struggle for people with cirrhosis.
Try these energy boosters
Whatever the cause of your fatigue, there are many lifestyle fixes you can make right now to lessen its impact and to help you get back on your feet.
Maintain a healthy weight
If you have hepatitis C and suffer severe tiredness, it’s important to keep your weight in check, as obesity also contributes to fatigue.
It may sound counterintuitive to get moving when you’re tired, but regular exercise boosts energy levels and contributes to your overall well-being, not to mention helping you control your weight. If strenuous cardio isn’t an option, try walking. Research suggests people with hepatitis C who walk regularly can improve their energy levels.
Avoid alcohol
Not only does alcohol further damage your liver cells, drinking makes you feel more tired and can contribute to feelings of depression. Smoking can also leave you feeling drained, so consider tossing the pack for good.
Eat small, nutritious meals throughout the day
Spacing out mealtimes gives your body constant fuel and keeps your metabolism humming. This can help bring you back from an energy slump. Pack your plate with fruits, veggies, whole grains, and other energy-boosting foods, and avoid fatty, processed selections that can leave you feeling even more sluggish and worn out.
Listen to your body
Some days are going to be easier than others. Don’t overdo it. If you feel like you need downtime, avoid cramming your day with activities. Conserve energy by completing certain tasks while sitting down. While you’re receiving treatment, focus on your health and avoid taking on any new stresses.
Remember to listen to what your body’s telling you and to prioritize rest; getting enough good-quality sleep is another key part of managing hep C.
