Tired all the time, no energy
You sleep, but you wake up tired. By noon you feel flat and heavy. Coffee helps for an hour, then it fades.
This kind of tiredness is not laziness. It is a sign your body is working harder than it should. Many things can cause it, and one of them is extra fat stored in the liver.
Doctors call that fatty liver, or NAFLD. Low energy is often the first thing people notice.
Some feel a dull ache under the right ribs. Many feel nothing else at all.
When to see someone
Go to the emergency room now if your skin or eyes turn yellow. Go now if you vomit blood, or if your stool is black and tarry. Go now if you have bad belly pain with fever.
Call your doctor the same day if your urine turns dark brown. Same day if your belly swells fast, or both legs swell. Same day if you feel faint or your heart races when you stand.
Book a visit within a week if the tiredness has lasted more than two weeks. Book a visit if you bruise with no cause, or bleed from small cuts for a long time. Book a visit if you lose weight without trying.
Ask for a sleep test if you snore loudly or gasp in your sleep. Ask for an iron test if you have heavy periods. Ask for help right away if you feel hopeless or think of harming yourself.
Why it happens
Your liver helps turn food into fuel. It also stores sugar and clears waste from the blood. When fat builds up inside it, the liver does this work less well.
Fatty liver often comes with high blood sugar and high blood fats. Your cells stop taking in sugar the way they should. So the fuel is in your blood, but not where your muscles need it.
A fatty liver can also be mildly swollen. Your body runs a low, steady clean-up response. That drains energy, even while you sit still.
What else it could be
The same tired feeling comes from many causes. Guessing wrong means you treat the wrong thing. Here is how they differ.
Low iron (anemia) makes you pale, short of breath on stairs, and cold. Your heart may race when you stand up. It is common in women with heavy periods.
A slow thyroid brings weight gain, dry skin, constipation, and cold hands. Hair may thin. This tiredness feels slow and foggy, not sleepy.
Sleep apnea makes you snore, gasp, or wake with a dry mouth and headache. You sleep eight hours and still feel wrecked. A partner often notices before you do.
Depression takes away interest, not just energy. Food and hobbies stop feeling good. Mornings are often the worst part of the day.
High blood sugar or diabetes brings thirst, more trips to the bathroom, and blurry sight. It often sits next to fatty liver, not instead of it.
Low vitamin B12 or low vitamin D can do it too. So can many drugs, such as blood pressure pills, antihistamines, and some antidepressants. Check the label of anything new you started.
A recent virus can leave you drained for weeks. Fatty liver tends to be quieter. It shows up on a blood test or scan, often by chance.
How to read the grades below
The options below come from our page on Non-Alcoholic Fatty Liver Disease (NAFLD). Each one carries two labels.
The first label is the evidence grade. A means strong trials in people, B means smaller or mixed studies, and C means early or limited findings. D means lab work only, and “insufficient” means the research cannot settle it yet.
The second label is the traditional tier. T3 means long use in more than one tradition, T2 means long use in one, and T1 means known use. T0 means no such record.
These grades come from research on Non-Alcoholic Fatty Liver Disease (NAFLD), the parent Health Topic, not on tired all the time no energy.
A grade tells you how strong the research is, not how well something will work for you. Talk to a doctor or pharmacist before you start anything, above all if you take other medicines.
What to try first
Get blood tests first. Ask for liver enzymes, blood sugar or HbA1c, iron, thyroid, and B12. This tells you which path to take.
While you wait, work on the basics. Walk 30 minutes most days.
Cut sugary drinks and fruit juice. Losing even 5 out of every 100 pounds can lower liver fat.
Some options have strong trial support. Omega-3 fatty acids (evidence grade A, traditional tier T0) can lower fat in the liver.
Berberine (evidence grade A, traditional tier T0) may help blood sugar and liver fat. Fasting (evidence grade A, traditional tier T3) is backed by trials and by long folk use.
Intermittent Fasting (evidence grade insufficient, traditional tier T0) is a looser, newer term.
The proof for it is thin so far. Do not fast at all if you are pregnant, under 18, or take insulin. Ask your doctor first.
Two options have fair support. Chicory (Persian Kasni) (evidence grade B, traditional tier T3) is both a folk herb and a study herb. TUDCA (evidence grade B, traditional tier T0) is a bile salt studied for liver health.
Two have weak support. Probiotics (Lactobacillus plantarum P8) (evidence grade C, traditional tier T0) target the gut.
Shilajit (evidence grade C, traditional tier T3) is a folk tar used in Ayurveda. Early results only.
Four more are used a lot, but the proof is thin. Milk Thistle (Silybum marianum) (evidence grade insufficient, traditional tier T2) is mostly folk use. Turmeric (evidence grade insufficient, traditional tier T3) is also mostly folk use.
Vitamin E (evidence grade insufficient, traditional tier T0) and Phosphatidylcholine (evidence grade insufficient, traditional tier T0) have not been proven here.
Tell your doctor about any supplement you take. Some clash with drugs. Berberine and blood sugar pills are one example.
How long it takes
Sleep and food changes can lift your mood in one or two weeks. Energy often moves before any test does.
Liver fat shifts more slowly. Studies that show change usually run 8 to 24 weeks. Blood tests are often redone at 3 or 6 months.
If you feel no better after 6 weeks of real effort, go back to your doctor. Another cause may be driving it. Nothing here is a sure thing, and results differ from person to person.
