Managing Depression Symptoms That Can Arise During Sickness
Mental health, illness and recovery
Physical illness, prolonged recovery and time away from everyday life can affect emotional wellbeing. Recognising changes early and accessing the right clinical, practical and workplace support can make recovery feel more manageable.
Being unwell does not only affect the body. Pain, fatigue, uncertainty, medical appointments, disrupted routines and time away from work or education can also affect mood, confidence and a person’s sense of identity.
Some people experience a temporary period of sadness or frustration while they are ill. Others develop persistent symptoms that may be consistent with depression. This may happen alongside a new diagnosis, a long-term health condition, an injury, surgery, repeated sickness absence or a slow and unpredictable recovery.
Depression is not a personal failing, and it should not be assumed that someone simply needs to be more positive. It is also important not to label every understandable emotional response to illness as a depressive disorder. The person’s symptoms, duration, daily functioning, medical circumstances and risks all need to be considered.
Low mood and depression are not always the same
Low mood may improve as circumstances change or the person begins to recover. Depression tends to involve symptoms that persist, affect everyday functioning and may be present even when there is no immediate setback. NHS guidance recommends seeking help if low mood has lasted for more than two weeks, is difficult to cope with or is not improving with self-help.
Why can sickness affect emotional wellbeing?
The relationship between physical and mental health is complex. Depression during sickness will rarely have one simple cause. Several pressures may interact at the same time.
Physical pressures
- Pain, fatigue or reduced mobility.
- Interrupted sleep and appetite.
- Medication effects or hormonal changes.
- Reduced independence.
- Uncertainty about recovery or prognosis.
Psychosocial pressures
- Isolation and reduced social contact.
- Loss of routine, purpose or identity.
- Financial and employment worries.
- Concern about burdening other people.
- Less access to enjoyable or regulating activities.
A person may also be managing pre-existing anxiety, depression, trauma, neurodivergence or caring responsibilities. These factors do not make depression inevitable, but they may influence how sickness is experienced and what support is needed.
Signs that someone may need additional support
Symptoms vary between individuals. Some overlap with the physical illness itself, so assessment should consider both physical and psychological explanations.
Possible signs include:
- Persistent sadness, emptiness or hopelessness.
- Loss of interest or pleasure in activities.
- Withdrawal from family, friends or colleagues.
- Strong feelings of guilt, worthlessness or being a burden.
- Difficulty concentrating, remembering or making decisions.
- Changes in sleep or appetite beyond those expected from the illness.
- Irritability, tearfulness or feeling emotionally numb.
- Reduced self-care or difficulty completing essential tasks.
- Thoughts of self-harm, suicide or not wanting to be alive.
A healthcare professional can consider whether symptoms may relate to depression, the underlying illness, medication, pain, sleep disruption or another condition. A questionnaire may support assessment, but diagnosis should not be based on a score alone.
Practical ways to support recovery
Advice should be proportionate to the person’s health and energy. A rigid list of tasks can feel overwhelming when somebody is already unwell. It may be more helpful to agree one or two realistic actions and review them regularly.
Helpful starting points may include:
- Tell someone: Share how things feel with a trusted person, GP or other healthcare professional.
- Create a gentle routine: Use a few predictable anchors such as getting dressed, eating regularly or opening the curtains.
- Protect connection: Arrange manageable contact by message, telephone or a short visit.
- Work with current capacity: Break activities into smaller steps and alternate effort with rest.
- Monitor patterns: Note changes in mood, sleep, pain, medication and functioning to discuss with clinicians.
- Use meaningful activity: Choose something achievable that offers comfort, interest or a sense of purpose.
- Avoid abrupt treatment changes: Speak to the responsible clinician before changing prescribed medication.
Suggestions such as exercise should always take account of the person’s medical condition. For some people, movement may support mood; for others, exertion may worsen symptoms or be clinically unsuitable. Individual medical advice takes priority over general wellbeing guidance.
When should someone seek professional help?
Speak to a GP or another appropriate healthcare professional if low mood has lasted for more than two weeks, is worsening, is affecting daily life, or if self-help is not enough. Help should also be sought sooner if there are concerns about safety, severe self-neglect, medication effects or a sudden change in mental state.
Treatment depends on the person’s circumstances and the severity of their symptoms. It may include monitoring, guided self-help, talking therapies, medication, support with physical-health management or a combination of approaches. Adults can self-refer to NHS Talking Therapies in many areas without first seeing a GP.
Preparing for an appointment
It may help to write down:
- When the mood changes began.
- How symptoms affect sleep, eating, self-care, relationships and work.
- Current physical symptoms and medication.
- Previous mental-health difficulties or treatment.
- Alcohol, drug or gambling concerns.
- Any thoughts of self-harm, suicide or feeling that others would be better off without you.
If someone may be in immediate danger
Call 999 or go to the nearest A&E if there is an immediate risk of suicide, serious self-harm or harm to another person.
For urgent mental-health help in England, call NHS 111 and select the mental-health option, or use NHS 111 online where appropriate.
Samaritans can be contacted free on 116 123. You can also text SHOUT to 85258 for free, confidential support. If you believe the risk is immediate and serious, do not leave the person alone while emergency help is being arranged.
Sickness absence and returning to work
Work can provide structure, identity and connection, but returning before the person is ready—or without suitable support—may increase distress. The aim should be a safe and sustainable return, where this is clinically appropriate, rather than simply returning as quickly as possible.
In Great Britain, employees can self-certify sickness absence for the first seven calendar days. If absence continues beyond this, an employer may request a fit note. A fit note can state that a person is not fit for work or may be fit for work if suitable support is available.
Support for staying in or returning to work might include:
- A phased return or temporarily reduced hours.
- A gradual increase in workload or responsibility.
- Temporary changes to duties or targets.
- More predictable hours, breaks or home working where appropriate.
- Time for treatment, counselling or medical appointments.
- Written priorities and regular, supportive check-ins.
- A named contact if the person becomes overwhelmed.
- An occupational-health assessment where this would assist planning.
Employment rights in Great Britain
What does the Equality Act 2010 mean?
Under section 6 of the Equality Act 2010, a person is disabled if they have a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities.
“Substantial” means more than minor or trivial. “Long-term” generally means that the effect has lasted, or is likely to last, for at least 12 months. A mental-health condition can meet this definition even when symptoms fluctuate or are not present all the time.
Depression is therefore not automatically a disability in every case. The legal test depends on the effect, severity and expected duration of the individual person’s condition. A formal diagnosis can provide helpful evidence, but the statutory definition focuses on the effect of the impairment.
Where an employer knows, or could reasonably be expected to know, that a worker is disabled, the Equality Act may require reasonable adjustments to remove or reduce a substantial disadvantage. What is reasonable depends on factors including effectiveness, practicality, cost, available resources and the employer’s circumstances.
Disability-related sickness absence
Treating all absence in exactly the same way can disadvantage a disabled worker. ACAS explains that a reasonable adjustment may sometimes involve changing how disability-related absence is recorded or managed—for example, adjusting absence-review trigger points or not counting some disability-related absence towards them.
This does not create an automatic right to unlimited absence, and an employer can still manage attendance and capability fairly. However, decisions should be individual, evidence-informed and made after properly considering reasonable adjustments and the person’s circumstances.
A supportive return-to-work plan should address what the person can currently manage, what creates difficulty and which changes may make work sustainable.
Talking to an employer
A worker does not necessarily need to share every detail of their diagnosis or treatment. It is often useful to explain the functional effect: what has become difficult, which work demands worsen symptoms and what support may help.
Requests can be made in writing so there is a clear record. A helpful conversation might cover:
- The main barriers affecting work.
- Advice contained in the fit note or occupational-health report.
- Proposed temporary or ongoing adjustments.
- How and when contact will take place during absence.
- How confidentiality will be maintained.
- A review date for any agreed arrangements.
- What should happen if symptoms worsen after returning.
When sickness, depression and neurodivergence overlap
Autistic and ADHD people may experience additional pressures during sickness, including disrupted routines, difficulty recognising internal bodily or emotional signals, sensory stress, executive-function demands and anxiety about communicating with employers or healthcare professionals.
Some may struggle to arrange appointments, complete forms, remember advice or explain how symptoms affect daily life. Others may appear outwardly composed while experiencing significant distress or exhaustion.
Helpful adjustments may include:
- Providing important information in writing.
- Agreeing one clear point of contact.
- Breaking plans into short, specific actions.
- Using reminders and exact dates.
- Allowing a trusted person to support appointments where appropriate and with consent.
- Reviewing sensory, communication and workload demands as part of return-to-work planning.
Supporting someone who is unwell and depressed
Support does not require having all the answers. Listening without judgement, maintaining gentle contact and helping with one practical task can be more useful than offering repeated advice.
Avoid assuming the person is lazy, exaggerating or choosing not to recover. At the same time, do not promise to keep suicidal thoughts secret. If risk is present, involve appropriate urgent or emergency support.
Understanding the whole person
Lycali’s approach
At Lycali, we recognise that physical health, emotional wellbeing, neurodevelopmental needs, relationships, employment and everyday functioning can interact.
Support should be based on an individual understanding of the person’s experiences, strengths, risks and goals. Depending on need, this may include psychological therapy, psychosocial assessment and intervention, neurodevelopmental assessment, psychoeducation or workplace-needs support.
Lycali is not an emergency or crisis service. Where immediate risk is identified, urgent NHS or emergency support should be accessed.
Recovery does not have to be managed alone
Depression symptoms can arise during sickness for many reasons. Recognising them does not undermine the reality of a physical condition, and seeking mental-health support does not mean the illness is “all in the mind”.
The most helpful response is usually coordinated and individual: address physical-health needs, assess emotional wellbeing, respond to risk, maintain manageable connection and consider practical or workplace adjustments.
If symptoms persist, worsen or interfere with everyday life, speak to an appropriately qualified healthcare professional. If there is immediate danger, seek emergency help.
