Recommended Recovery Times for Common Illnesses, Surgeries, and Procedures
Recovery times vary from person to person. How long any illness or operation keeps someone away from work depends on the condition itself, the type of surgery, the person’s age and general health, whether there were complications, and how physically demanding the job is. The timeframes below are drawn from published NHS guidance and are offered as general information for employees, employers and anyone planning sick leave. They are not a prediction for any individual: the clinician or surgical team who has assessed you decides when it is safe for you to return.
Common Illnesses: Recovery Timeframes
Every figure in this table is taken from NHS guidance on the condition named. Where the NHS publishes no timeframe, that is stated rather than filled in with an estimate.
| Illness | Typical recovery time | Return to work guidance |
|---|---|---|
| Common cold | 1 to 2 weeks, and longer in babies and young children | NHS advises staying at home and avoiding contact with others if you have a high temperature or do not feel well enough to do your normal activities. The NHS notes you are infectious until all your symptoms have gone |
| Influenza (flu) | The NHS publishes no fixed duration for flu | NHS advises staying at home and avoiding contact with others while you have a high temperature, feel hot, cold or shivery, or do not feel well enough for your normal activities. There is no NHS rule about being free of fever for a set number of hours before returning |
| COVID-19 | Most people feel better within a few weeks, but it can take longer | NHS advises adults with symptoms or a positive test to try to stay at home and avoid contact with other people for 5 days after the day the test was taken, and 3 days for under 18s. This is guidance, not a legal requirement |
| Gastroenteritis (stomach bug) | Vomiting usually stops in 1 or 2 days, diarrhoea usually within 5 to 7 days | NHS advises staying off school or work until you have not been sick or had diarrhoea for at least 2 days |
| Tonsillitis | Symptoms usually go away after 3 to 4 days but can last longer | NHS advises staying at home while you have a high temperature or do not feel well enough for your usual activities. Recovery from a tonsillectomy is a separate and longer matter, covered in the procedures table below |
| Chest infection and pneumonia | Most people get better in 2 to 4 weeks, depending on symptoms | A cough and tiredness often outlast the infection itself. Physically demanding roles commonly need longer than the figure above, which your clinician will judge |
| Urinary tract infection (UTI) | The NHS publishes no fixed duration | NHS advises contacting a GP if symptoms get worse quickly or do not improve within 48 hours of starting treatment. Many people feel able to work once treatment takes effect |
| Migraine | Attacks usually last between 4 hours and 3 days | Early symptoms such as feeling very tired can start hours, or up to 2 days, before the head pain and can continue after the headache stops |
| Anxiety or depression episode | Highly individual. The NHS publishes no standard absence period | A phased return is often recommended. Under GOV.UK rules an employee off for 7 days or less does not need to give their employer a fit note or other proof of sickness from a healthcare professional |
| Burnout | No published NHS timeframe. Commonly a matter of weeks or longer | Gradual reintroduction. Addressing the workplace triggers and agreeing adjustments usually matters more to a durable return than the length of the absence |
| Back pain (acute) | Usually improves within a few weeks, but can last longer or keep coming back | NHS advises staying active and continuing daily activities where you can, and warns against long periods of bed rest. Sedentary workers often return sooner than those doing manual work |
| Kidney stones | The NHS publishes no fixed time for a stone to pass | Most stones are small enough to pass in your urine. Return when pain is controlled and any planned procedure is complete, as advised by the treating team |

Surgery and Procedures: Recovery Timeframes
Time off work after an operation is set by the surgical team, who know what was done and how it went. The figures below are the general ranges the NHS publishes for each procedure, and an individual operation can sit well outside them.
| Procedure | Typical time off work | Notes |
|---|---|---|
| Appendix removal (appendicectomy) | Commonly 1 to 2 weeks | Recovery is generally quicker after keyhole surgery than after an open operation. Longer if the appendix burst or there were other complications, and longer again for heavy manual work. Your surgical team advises |
| Gallbladder removal | 1 to 2 weeks, depending on the type of work you do and the type of surgery you had | NHS advises not driving until you can do an emergency stop without pain or discomfort, and checking your insurance policy for rules about driving after surgery |
| Hernia repair (inguinal) | Usually at least 1 to 2 weeks, or up to 6 weeks if your job involves heavy lifting | NHS advises no heavy lifting or strenuous activity for at least 4 to 6 weeks, and no driving after surgery until your healthcare team and insurance provider say you may |
| Hip replacement | Usually about 6 weeks, depending on the type of work you do | NHS advises waiting at least 6 weeks to drive and checking with your doctor that you are fit to drive. Manual roles commonly need longer than 6 weeks |
| Knee replacement | Usually about 6 to 12 weeks, depending on the type of work you do | Full recovery may take several months or longer. NHS advises waiting at least 6 weeks to drive after a total knee replacement, or 3 weeks after a partial one, and checking with your doctor that you are fit to drive |
| Hysterectomy | About 6 to 8 weeks to recover fully after an abdominal hysterectomy | Return to non-manual work may be possible after 6 to 8 weeks. NHS advises not driving until you are comfortable wearing a seatbelt and can safely perform an emergency stop, which can be anything from 2 to 6 weeks after the operation |
| Caesarean section | You must take at least 2 weeks’ leave after the birth, or 4 weeks if you work in a factory | This is compulsory maternity leave under GOV.UK rules, not a recovery estimate. The NHS says you will probably be in hospital for 1 or 2 days and may need to take things easy for several weeks, and that returning to activities such as driving may not be possible for 6 weeks or so |
| Cardiac surgery (bypass or valve) | Varies widely with the operation and the person. Your cardiac team sets the return to work date | DVLA rules: after a coronary artery bypass graft a Group 1 car or motorcycle driver must not drive for at least 4 weeks but need not notify DVLA. After valve surgery the Group 1 period is 4 weeks for a surgical procedure and 2 weeks for a percutaneous valve intervention. Group 2 lorry or bus drivers must not drive for 3 months and must notify DVLA. Sternal precautions from your surgical team apply |
| Cataract surgery | Vision may take several days to improve, and can be blurry for a few hours immediately afterwards | Do not drive yourself home on the day. NHS advises not driving until your vision is back to normal, and your eyesight must meet the DVLA standard before you drive |
| Tonsillectomy | Commonly about 2 weeks | Bleeding can occur for up to about 2 weeks after the operation, and pain often gets worse before it gets better, typically around 5 days in. NHS trust guidance advises avoiding exercise and swimming for the first 2 weeks. Any bleeding needs urgent assessment |
| Colonoscopy (diagnostic) | Usually the day of the procedure | If you had sedation the NHS says you cannot drive for 24 hours and someone will need to collect you. Bloating or cramps for a few hours afterwards are normal |
| Varicose vein treatment | 1 to 2 weeks off work after ligation and stripping surgery | After endothermal ablation or foam sclerotherapy the NHS says most people can go back to most usual activities straight away, though pain and bruising are common |
| Broken arm or wrist | Usually around 6 to 8 weeks to recover | NHS advises not driving or lifting heavy items until you have been told it is safe. Desk-based workers may manage sooner with adjustments, manual workers usually cannot |
| Cancer treatment (chemotherapy) | Highly variable, with no general timeframe | Effects build over a treatment cycle and immune suppression means an individual risk assessment is needed. Your oncology team advises on work |

Mental Health Conditions: Recovery and Return to Work
Mental health conditions are among the most common causes of long-term sickness absence in the UK. The NHS does not publish standard absence periods for them, and any figure that claims to is an estimate rather than guidance. Recovery is individual and can fluctuate, and a period of apparent recovery may be followed by relapse, particularly where workplace stressors have not been addressed.
| Condition | Published NHS absence period | Return to work considerations |
|---|---|---|
| Stress and burnout | None published | A phased return is common. The cause of the stress needs addressing, and reasonable adjustments should be considered, particularly where the Equality Act 2010 applies |
| Anxiety disorder | None published | Adjusted duties, home working or reduced hours may support a return. Talking therapies run over a course of sessions rather than a fixed absence |
| Clinical depression | None published | The NHS says antidepressants usually take 1 to 2 weeks to start having an effect and can take up to 8 weeks to work fully, so a return planned around medication needs to allow for that |
| PTSD | None published | NHS says symptoms may start straight after the traumatic event or months or years later, and that PTSD usually gets better for most people, though symptoms can be more severe and last longer for some. Trigger avoidance and a trauma-informed return plan matter |
| Bipolar disorder (episode) | None published | Mood stabilisation before a return, then gradual reintroduction, guided by the treating team |

Need a sick note for work?
MedicalCert issues a private sick note from a GMC-registered UK doctor after an online clinical assessment, for £47, suitable for your employer’s absence records. It is a private certificate, not an NHS Med3 fit note, and DWP benefit claims including ESA need a Med3 fit note from your registered GP.
Sick Pay While You Recover
Recovery time and sick pay are separate questions. How long you are unfit for work is a clinical judgement. What you are paid during that time is set by statute and by your contract.
Statutory Sick Pay changed on 6 April 2026. The three unpaid waiting days were abolished, so SSP is payable from the first qualifying day of the absence rather than the fourth. The Lower Earnings Limit was removed by the Employment Rights Act 2025, so employees earning below the old threshold are no longer excluded from SSP on earnings grounds.
For 6 April 2026 to 5 April 2027 the weekly rate is £123.25, or 80% of your average weekly earnings, whichever is lower. SSP runs for up to 28 weeks in a single period of sickness or in linked periods. Many employers pay contractual sick pay above this, so check your own absence policy.
On evidence, you can self-certify for the first 7 days in a row, including non-working days. After that your employer can ask for medical evidence. GOV.UK tells employers that if they agree, the employee can give another appropriate form of evidence instead of a fit note.
Full detail, including eligibility and how SSP is worked out, is in our Statutory Sick Pay guide.
