Hidden Harm: Domestic Abuse During Serious and Long-Term Illness

Domestic abuse is often discussed as a social issue, separate from health. Yet UK research increasingly shows that it is deeply connected to serious and long-term illness. Whether someone is living with cancer, chronic obstructive pulmonary disease (COPD), cardiovascular disease, diabetes or other life-limiting conditions, the experience of illness can increase vulnerability to abuse in ways that remain largely hidden.

At the same time, domestic abuse itself is now recognised as a major contributor to poor physical and mental health outcomes. The relationship runs in both directions and the consequences can be profound.

Illness, Dependency and Risk

Serious illness frequently brings changes that affect independence and control over daily life. Across conditions such as cancer, COPD, heart disease, and diabetes, people may experience:

• Fatigue, pain, or reduced mobility

• Increased reliance on partners or family for care

• Financial strain or inability to work

• More time spent at home

• Complex medication or treatment routines

UK research highlights that people with life-limiting illness are often “frail, isolated and dependent on others”, increasing their risk of domestic abuse and reducing their ability to seek help¹.

Abuse in these contexts may include:

• Controlling or withholding medication (e.g. insulin, inhalers, cardiac drugs, cancer therapies)

• Interfering with medical appointments or treatment plans

• Emotional abuse linked to illness (“you’re a burden”)

• Financial control, especially where illness affects income

• Neglect of care needs

In these situations, illness is not incidental—it becomes part of how abuse is carried out.

Equal Impact Across Conditions

While cancer often receives attention due to its visibility, other long-term conditions can create similar or even greater vulnerability.

Cancer
Treatment pathways such as chemotherapy, radiotherapy, and surgery can create periods of intense dependency, increasing reliance on others for care and support.

COPD
COPD is associated with breathlessness, reduced mobility, and social isolation. UK studies highlight that people with COPD frequently experience loneliness and require ongoing support.

Cardiovascular Disease
Heart conditions often involve fatigue, reduced physical capacity, and strict medication regimens. Stress linked to abuse can worsen cardiovascular outcomes.

Diabetes
Diabetes requires continuous self-management. This creates opportunities for coercive control, including restricting food, interfering with insulin, or undermining care routines.

Other Long-Term Conditions
Neurological disorders, chronic pain, and frailty in older age similarly increase dependency and reduce the ability to leave abusive environments.

Across all these conditions, the shared risk factors are dependency, reduced autonomy, and increased exposure to controlling relationships.

Abuse as a Driver of Ill Health

The relationship between abuse and illness is not one-way. UK evidence shows that domestic abuse is associated with:

• Increased risk of cardiometabolic disease, including heart disease and diabetes

• Significantly increased mental health conditions

• Greater healthcare use and hospitalisation

• Higher rates of chronic pain and fatigue-related conditions - Emerging research also highlights a significant association between domestic abuse and fibromyalgia. People who have experienced prolonged trauma are considerably more likely to develop fibromyalgia, a long-term condition characterised by widespread pain, extreme fatigue, sleep disturbance and problems with memory and concentration ("fibro fog"). While the exact cause of fibromyalgia remains unknown, researchers increasingly recognise that traumatic experiences, including domestic abuse, can play an important role in its development or trigger flare-ups in those already living with the condition.

This creates a cycle:

• Abuse contributes to worsening health

• Illness increases dependency

• Dependency increases vulnerability to further abuse

Why It Often Goes Unseen

Despite frequent contact with healthcare services, domestic abuse is often not identified.

UK research highlights several barriers:

• Clinical focus on physical illness rather than social context

• Limited time during appointments

• Lack of training or confidence in asking about abuse

• Fear of not having appropriate support pathways

The NIHR-funded DALLI study found that domestic abuse in life-limiting illness is under-recognised and under-researched, despite clear risks.

For patients, additional barriers include:

• Fear of losing care if the abuser is also the caregiver

• Physical inability to seek help

• Social isolation

A Public Health Issue

Domestic abuse is increasingly recognised in the UK as a public health issue. Its impact includes:

• Poorer disease management

• Reduced adherence to treatment

• Increased complications

• Lower quality of life

• Potentially reduced survival in serious illness

For individuals managing cancer, COPD, cardiovascular disease, diabetes, or other chronic conditions, abuse can directly affect both recovery and long-term outcomes.

Domestic abuse doesn't only leave emotional scars. It can have lifelong physical consequences too. As evidence continues to grow around the links between trauma, chronic illness and conditions such as fibromyalgia, it's more important than ever that healthcare professionals, employers, family members and communities recognise the hidden impact of abuse and ensure survivors receive compassionate, trauma-informed support.
