Almost 70 per cent of men and 60 per cent of women in England are overweight or obese, according to data from the British Nutrition Foundation (BNF), which can have serious long-term consequences for their health.
Not only does living with obesity or being overweight affect a person’s quality of life and contribute to mental health problems, such as depression, but people living with obesity are at increased risk of developing type 2 diabetes, coronary heart disease and stroke, and cancer.
Maintaining or achieving a healthy weight can be challenging for many people, but pharmacy teams are in the ideal position to expertly – and sensitively – explain the long-term health risks and what to do to avoid them.
Diabetes
In the UK, it is estimated that 3.8 million people aged over 16 years have been diagnosed with diabetes and nearly one million are unaware that they have the condition.
Type 1 and type 2 diabetes occur when sugar in the blood cannot be used properly, and this can cause serious health complications over time involving the eyes, heart, kidneys, feet and nerves.
About 90 per cent of people with diabetes have type 2 diabetes, which is strongly linked with being overweight or obese. Indeed, according to figures from the BNF, around 90 per cent of people diagnosed with type 2 diabetes are overweight or obese.
People can mitigate most risk factors for type 2 diabetes by eating a healthy, varied diet, being physically active and losing weight (if necessary), and some are even able to put their diabetes into remission by losing weight and reducing their blood sugar to below the diabetes range. The condition can also generally be treated in the same way – although sometimes medications such as metformin and/or insulin are also prescribed.
Heart disease and stroke
In the UK, heart disease is one of the major causes of premature death (before 75 years) and a leading cause of ill health.
The condition that causes most heart attacks and strokes is known as atherosclerosis – a build-up of fatty material that narrows arteries and can restrict blood flow to heart. This can cause the symptoms of angina (such as chest pain and shortness of breath), and if the fatty material breaks down a blood clot can form which can completely block the artery and lead to a heart attack or, if the rupture happens in arteries in the brain, a stroke.
There are several risk factors for atherosclerosis and heart disease including high blood pressure (hypertension), high blood cholesterol, a family history of heart disease, as well as diabetes, and being a smoker – but a lack of exercise and being overweight or obese are known to increase blood pressure and cholesterol levels which are risk factors for developing heart disease.
The more risk factors a person has, the greater their chances of suffering from heart disease so, again, pharmacy teams’ expert advice on healthy eating and physical exercise – as well as stopping smoking, cutting down on alcohol, and reducing salt intake to less than six grams a day – can help people reduce their overall risk.
