Non-communicable diseases

Non-communicable diseases

Diabetes, high blood pressure and asthma are common conditions that may not seem like humanitarian emergencies.

However, when conflict, disaster or mass displacement leave patients cut-off from their care, the everyday can fast become life-threatening.

What is a non-communicable disease?

Non-communicable diseases (NCDs) are diseases that cannot be directly transmitted between people. Many are chronic diseases, meaning that they stay with people for life.

These long-term illnesses are due to a combination of genetic vulnerabilities and environmental factors, such as poverty, living in polluted surroundings, unreliable access to food or poor diet, tobacco and alcohol use.

NCDs are incredibly widespread and often have a life-limiting impact. According to the World Health Organization, NCDs kill 41 million people each year. This accounts for a massive 74 percent of all deaths globally.

Types of NCDs

NCDs cover a vast area of medical practice and include complex conditions as varied as Alzheimer’s disease, osteoporosis and autoimmune disorders.

Within this, there are four main groups that cause 80 percent of all “premature” NCD deaths:

Cardiovascular diseases (such as heart attacks and hypertension)
Chronic respiratory diseases (including COPD and asthma)
Diabetes
Cancer

Why does MSF treat long-term illnesses?

Médecins Sans Frontières/Doctors Without Borders (MSF) is well-known for launching rapid emergency responses to catastrophic humanitarian events.

Caught-up in the middle of every crisis are people living with chronic diseases who can no longer rely on stable and accessible healthcare to manage their condition safely. And, when healthcare systems begin to fail, so does the detection and routine screening of potential NCD patients.

NCDs also disproportionately impact people living in the places where we work, with three-quarters of all global NCD deaths occurring in low-income and middle-income countries.

Batil is one of three camps in South Sudan’s Upper Nile State sheltering at least 113,000 refugees who have crossed the border from Blue Nile state to escape fighting between the Sudanese Armed Forces and the SPLM-North armed group. Refugees arrive at the camp with harrowing stories of being bombed out of their homes, or having their villages burned. The camps into which they have poured are on a vast floodplain, leaving many tents flooded and refugees vulnerable to disease. Mortality rates in Batil camp are at emergency levels, malnutrition rates are more than five times above emergency thresholds, and diarrhea and malarial cases are rising.

How does MSF treat NCDs?

The reality is that as an emergency medical organisation, we often work in remote and dangerous places with limited resources. This means it can become incredibly challenging and costly to treat every form of NCD.

We prioritise treating the most vulnerable people, focusing on conditions that cause the greatest number of deaths, disability and suffering. As well as this approach toward some of the most widespread NCDs, there are also a small number of other conditions that we treat as part of specific projects.

We do this all in a way that is centred on people’s needs, makes the best use of resources and ultimately saves lives.

Cardiovascular diseases affect the heart and blood vessels. They include conditions such as heart attacks, strokes, hypertension (high blood pressure) and coronary heart disease.

They are the number one cause of death globally, killing an estimated 17.9 million people each year.

However, most conditions can be prevented by addressing risk factors such as smoking, drinking, unhealthy diet and lack of physical activity. They can also be caused by other NCDs such as diabetes.

Early detection of people at high risk is key to fighting cardiovascular diseases, as well as access to basic medicines and technology in primary healthcare centres.

Chronic respiratory diseases affect the airways and structure of the lungs. The most common forms are chronic obstructive pulmonary disease (COPD) and asthma, which around 622 million people suffer from, particularly children.

Risk factors include smoking, air pollution and exposure to chemicals and dust.

Chronic respiratory diseases are not curable, however, with treatment including medication (such as an inhaler) and behaviour changes, patients can control their symptoms.

Diabetes is a chronic disease that occurs when the body does not produce enough of the hormone insulin to regulate blood sugar. Over time, high blood sugar levels eventually lead to cardiovascular disease, kidney failure, blindness and nerve damage.

Around 422 million people worldwide live with diabetes, a number that has been rising steadily for decades, while 1.5 million deaths are directly attributed to the disease every year.

There are two forms of diabetes:

Type 1, also known as insulin-dependent diabetes, is a life-long condition often diagnosed at a young age. It is caused when the pancreas produces very little or no insulin.
Type 2, which is the most common form, usually occurs in adults when the body has become resistant to insulin. Risk factors include being overweight and a lack of exercise.

For people living with diabetes, access to affordable insulin or oral medication is vital to survive. However, for patients living in humanitarian crises, issues such as storage of insulin and food insecurity complicate their condition further.

Cervical cancer kills around 342,000 women a year, with 90 percent of new cases and deaths occurring in low-income and middle-income countries.

Nearly all cases are caused by human papillomavirus, also known as HPV, a common sexually transmitted infection.

In most women, the virus spontaneously clears. For others, chronic infection can progress to cancer over a period of 15-20 years. The infection is particularly aggressive in HIV-positive women.

However, HPV is entirely preventable, detectable and treatable.

MSF carries out routine HPV vaccinations as part of many sexual and reproductive healthcare projects, as well as simple “screen-and-treat” programmes that can have a life-saving impact but require little infrastructure.

Unfortunately, wider cancer treatment is not something we are usually able to provide as part of an emergency medical response.
