What grief does to the body

Grief is treated as an emotional matter. It has substantial physical effects, and there is a body of research on them that is worth knowing about — both to reassure people that what they are experiencing is normal, and to flag the risks that are real.

The symptoms people report

Exhaustion out of proportion to activity. Disturbed sleep, both difficulty falling asleep and early waking. Appetite changes in either direction. Chest tightness and a sensation of breathlessness. Aches, particularly in the shoulders and neck. Digestive disturbance. Headaches. Increased susceptibility to minor illness.

Cognitive effects: poor concentration, forgetfulness, losing things, difficulty following a conversation or reading a page.

Many bereaved people worry that these indicate something serious. They are a normal feature of grief and they generally resolve.

The documented risks

Several findings from research are worth being aware of.

Elevated mortality in the bereaved. A substantial body of epidemiological research has found increased mortality risk in the period after a spouse's death, sometimes described as the widowhood effect.

The elevation is greatest in the first weeks and months and diminishes over time. It affects both men and women, with findings varying by study on the relative magnitude.

Cardiovascular events. Research has found an increased risk of myocardial infarction in the days immediately following a bereavement, with the risk highest on the first day and declining thereafter.

Stress cardiomyopathy. A recognised condition, sometimes called broken heart syndrome, in which acute emotional stress produces a temporary weakening of the heart muscle presenting like a heart attack.

It is generally reversible and it is genuinely a cardiac event requiring assessment.

Immune changes. Studies have found alterations in immune function in bereaved people, with some evidence of increased susceptibility to infection.

Sleep disruption, which is near-universal and which has its own downstream effects on mood, cognition and health.

The behavioural contributors

Some of the physical effect is mediated by behaviour, which matters because behaviour is modifiable.

Reduced eating, or eating badly. Bereaved people frequently stop cooking, particularly where they cooked for someone else.

Increased alcohol. Common, and it worsens sleep, mood and health while appearing to help.

Reduced activity.

Neglected medical care. Missed appointments, unfilled prescriptions, ignored symptoms.

This last one is significant. Bereaved people frequently stop attending to their own health at exactly the point when the risk is elevated.

What to do

The advice is unglamorous and it is what the evidence supports.

Eat something regularly, even if you do not want to. If cooking is the obstacle, accept food from people, use simple things, and do not aim high.

Keep taking your medication and keep your appointments.

Tell your doctor you have been bereaved. This is worth doing explicitly. It provides context for symptoms, it flags the elevated risk, and in many systems it triggers additional attention.

Be careful with alcohol. The most common self-medication and the one that most reliably makes things worse.

Move. A walk, most days. There is reasonable evidence for physical activity and mood, and it also addresses sleep.

Protect sleep as far as you can, with the usual measures, and accept that it will be disrupted for a period.

Do not drive when severely distracted, which is a genuine and under-discussed risk in the early weeks.

When to see a doctor

Any chest pain, particularly in the first weeks. Do not attribute it to grief without assessment.

Breathlessness that is new or severe.

Any symptom you would normally have investigated. The tendency to dismiss everything as grief means real conditions are missed.

Persistent inability to sleep beyond several weeks.

Weight loss that is significant.

Low mood that is not lifting at all, or thoughts of self-harm.

If you are managing a chronic condition and your control has deteriorated.

For older bereaved people

The risks are higher, and the practical situation is frequently worse — the person who died may have been the one who cooked, drove, managed medication, or provided the only regular contact.

Practical support in the first months matters disproportionately: help with meals, with transport, with medication, and regular contact.

Family members should be alert to weight loss, missed medication, and social isolation, all of which develop quietly.

The reassurance

Most of the physical symptoms of grief are normal, temporary and not dangerous.

The point of knowing about the documented risks is not to worry but to take the ordinary precautions — eat, keep appointments, moderate alcohol, get chest pain checked — during a period when people are least inclined to look after themselves.

Chest pain or breathlessness requires medical assessment regardless of circumstances. Tell your doctor you have been bereaved, and do not stop attending to existing health conditions.
