Fatigue and low energy
Feeling drained can make work, concentration and everyday tasks harder. This guide explains what to notice, how a GP can help and when to seek care sooner.
Can I discuss fatigue or low energy with an online GP?
A HerDoc GP can assess persistent tiredness, review your health history and medicines, and help plan treatment or follow-up. You can book without knowing the cause. The GP can talk through when it happens and how it affects your day, then explain whether an examination or testing would help.

When tiredness becomes a concern
An occasional tired day after poor sleep or a busy week often improves with rest. Fatigue can feel more persistent: you may struggle to start usual tasks, tire quickly or still feel drained after sleep. It can affect your body, concentration and motivation.
Arrange a GP review if tiredness lasts more than two weeks without improving, keeps returning or limits daily life. You can seek help sooner if the change worries you. You do not need to wait until you are unable to work.
What can contribute to low energy?
Several factors can act together. Interrupted sleep, shift work, caring responsibilities, stress, grief or low mood may matter. Recent illness, changes in eating, alcohol use and some medicines can also affect energy. Physical health conditions, including anaemia or thyroid problems, are other possibilities.
Heavy periods, pregnancy and changes around perimenopause or menopause can be relevant. For example, night sweats may interrupt sleep. These connections do not establish a cause, and fatigue should not automatically be put down to stress or hormones.
What helps a GP understand your fatigue?
A few notes are enough; do not delay care to complete a diary. Include what has changed from your usual energy and which activities are difficult. Have these details handy:
- When it began, whether it comes and goes, and whether rest helps.
- Sleep times, waking during the night, snoring, breathing pauses noticed by someone else or unplanned daytime dozing.
- Mood, stress, recent illness and whether activity leaves you feeling worse later that day or the next.
- Period or other bleeding changes, pregnancy possibility and life-stage changes.
- Current medicines and supplements, recent treatment changes, existing conditions and advice already tried.
- Changes in diet, appetite or weight, and other symptoms such as pain, fever, breathlessness or bowel changes.
Earlier results can help
You can upload relevant results or other images and PDFs during intake. Include the report date and why the test was done. HerDoc does not automatically receive results ordered elsewhere.
How can an online GP help?
A HerDoc GP can review your symptoms and medicines, discuss treatment, order blood tests and provide a referral. The useful next step depends on your history and what needs investigating. Care may focus on sleep, mood, nutrition, a medicine-related concern or an underlying health condition.
A phone appointment cannot examine you or measure things such as your pulse or blood pressure. The GP may recommend a local examination or specialist advice to investigate further. Serious causes cannot be ruled out remotely.
Why not order every possible blood test?
Testing is useful when it answers a question that could change your care. For example, heavy periods with tiredness may lead a GP to check for anaemia. Your symptoms, previous results and any examination help guide the choice; this is not a test everyone with fatigue needs.
Ordering a broad range of tests can find changes unrelated to your symptoms and lead to further tests that do not help explain the fatigue. Sometimes reviewing the pattern or examining you is more useful first. If tests are recommended, ask what they are checking, who will review the results and when to follow up.
What can you do while fatigue is being assessed?
Treatment depends on the contributors; a single approach will not suit everyone. Practical steps can support you while the cause is being explored:
- Aim for a regular sleep routine where possible, and discuss persistent poor sleep or daytime dozing.
- Make time for regular meals and fluids. Mention restricted eating or difficulty getting enough food rather than starting supplements on the assumption of a deficiency.
- Balance activity with rest and break demanding tasks into smaller parts. If activity causes a noticeable worsening afterwards, avoid pushing through and discuss this with the GP.
- Have medicines reviewed if you suspect they contribute. Do not stop or change prescribed treatment on your own.
- Do not drive or operate machinery when tiredness or sleepiness makes it unsafe. Arrange another way to travel.
If symptoms persist, return or change
Before finishing the appointment, agree on what to try, what to watch for and when to review progress. Bring new symptoms or a worsening effect on daily life back to the GP; do not wait for a planned review if you become unwell.
HerDoc welcomes repeat appointments. Rebook through your dashboard or portal with the same GP when available, or another GP. Each follow-up or results appointment is separately booked and paid.
When to seek urgent or local care
Fatigue on its own is usually a reason for a GP review, not emergency care. Symptoms that occur alongside it can change the urgency.
Call 000 for an emergency
Call 000 if you have any of the following. Do not wait for a phone appointment or drive yourself.
- Chest pain or severe breathing difficulty.
- Collapse or loss of consciousness, including fainting.
- Uncontrolled heavy bleeding.
- Sudden weakness on one side, facial drooping or difficulty speaking.
- Sudden confusion.
Seek prompt local assessment
Seek same-day medical advice for rapidly worsening illness, marked new weakness, significant bleeding or fever with feeling very unwell. New unexplained weight loss or persistent fever also needs a timely GP assessment.
If vomiting or poor fluid intake leaves you unable to keep fluids down, passing very little urine, or markedly dizzy or weak, seek urgent local assessment now. You do not need to have all these signs. Severe dehydration needs immediate medical treatment; call 000 for collapse, confusion or severe deterioration.
Pain or bleeding with possible pregnancy
Contact your doctor, midwife or maternity service straight away for vaginal bleeding during pregnancy. If pregnancy is possible and you have vaginal bleeding or new pelvic or abdominal pain, seek prompt medical advice rather than waiting for a routine fatigue appointment.
Severe abdominal pain, shoulder-tip pain, heavy bleeding or feeling faint with possible pregnancy needs immediate emergency assessment. Call 000 if you collapse, have severe symptoms or cannot travel safely.
Thoughts of self-harm or suicide
Seek help now rather than waiting for a routine fatigue appointment. If you may act on these thoughts or cannot stay safe, call 000 or go to an emergency department. Otherwise, contact a GP or mental-health service promptly; Lifeline provides 24-hour crisis support on 13 11 14.
FAQs
What if my blood tests were normal but I still feel exhausted?
Normal results do not mean the fatigue is imaginary or explain every possible cause. Arrange a review of what was tested, how symptoms have changed and what remains difficult. The GP can revisit sleep, medicines and other contributors and decide whether examination or further investigation would help.
Can I keep my usual GP involved?
Yes. You can ask the HerDoc GP during your appointment to send a consultation summary or relevant results to your regular GP. Sharing is not automatic; let the doctor know which clinician is already involved in your care.
