Chronic Fatigue: Why Am I Always Tired?

You wake up tired, drag yourself through the day and collapse at night, and still it does not go away. People tell you to "just rest", but rest does not seem to fix it. Feeling this way is very common, and it is worth taking seriously, because tiredness is the body's way of saying something needs attention.

What is happening

Fatigue is not one thing. It can come from the body, the mind, your circumstances or all three together.

Common body causes include poor or broken sleep, sleep apnoea, low iron (anaemia, especially with heavy periods or pregnancy), an underactive thyroid, diabetes, low vitamin B12, infections such as TB or HIV, recovering from COVID-19 or flu, side effects of medicines, and not eating or drinking enough. Common mind causes include stress, depression, anxiety and grief. Circumstances matter too: long shifts, caring for a sick relative, a new baby, a long commute, black tax pressure and money worry are draining in their own right.

Burnout is the tiredness of too much demand for too long with too little recovery. Some people develop a longer-term condition called ME/CFS (myalgic encephalomyelitis or chronic fatigue syndrome), where even small effort leads to a crash a day or two later. This needs a proper medical assessment, not pushing through.

Signs to notice

• Tiredness that has lasted more than a few weeks and is not explained by a busy patch
• Needing much more effort to do ordinary tasks
• Feeling worse for a day or two after activity
• Brain fog, forgetting things, losing words
• Low mood, losing interest, or feeling flat
• Getting ill more often than before

30-second self-check

Answer yes or no for the last month:

• Have you felt tired most days for more than four weeks?
• Do you sleep six hours or less on most nights, or wake unrefreshed?
• Has anyone told you that you snore loudly or stop breathing in your sleep?
• Do you skip meals or live mainly on bread, sugar and tea?
• Do you feel low, hopeless or uninterested in things you used to enjoy?
• Are you carrying heavy caring, work or money pressure with little break?
• Have you had unexplained weight loss, night sweats or a cough for two weeks or more?

0-1 yes: Your tiredness may be a passing phase. Protect sleep and meals and check again in two weeks.
2-3 yes: Several drains are adding up. Tackle one this week and book a basic health check.
4 or more yes: Please see a clinic nurse or doctor soon for a check-up and blood tests.

What you can do next

• Today: Eat breakfast with some protein (an egg, peanut butter, beans or maas) and drink water through the day. Notice when your energy dips.
• This week: Keep a regular wake-up time and cut caffeine after lunch. Write down three things that drain you and one you can drop or share.
• This month: Book a check-up at your clinic or GP. Ask about a blood count (for iron), blood sugar, thyroid, and HIV and TB tests if they apply to you. Bring a list of medicines you take.
• Pace yourself: On good days, do not overdo it. Break tasks into smaller parts with rests in between.
• Move gently: A short daily walk often lifts energy over time, unless activity clearly makes you crash, in which case speak to a doctor first.

When to get professional help

See a doctor or clinic if tiredness lasts more than four weeks or is getting worse. See a doctor today if fatigue comes with unexplained weight loss, drenching night sweats, a cough for two weeks or more, coughing blood, very pale skin, fainting, or yellow eyes. Call Ambulance 10177 or 112 from a mobile if you have chest pain, severe breathlessness, confusion or signs of a stroke such as face drooping, arm weakness or slurred speech. If tiredness is tied up with feeling hopeless, that is also a reason to reach out now, not later.
