These Common Conditions Are Quietly Cutting Lives Short

This Order of Diseases Can Steal 13 Years from Your Life

Understanding the Prevalence of Multiple Conditions

In the UK, and no doubt this is similar in other parts of the developed world, more than 25% of adults have two or more long-term health conditions. This rate jumps to 65% for people over 65 years old and reaches almost 82% for those aged 85 or older. These numbers underline a major public health issue that demands your attention, especially as you age.

What This Study Looked At

This study assessed how three specific long-term conditions — psychosis, diabetes and congestive heart failure — develop over time and what this means for your life expectancy. These conditions were chosen because, when they occur together, they can significantly reduce how long you live.

The researchers analyzed 20 years of data covering more than 1.6 million adults aged 25 and above, using anonymized health and administrative records from the SAIL databank in Wales. They also gathered insights from patients and the public across the UK to understand what it’s really like to live with multiple long-term conditions.

Why the Order of Disease Matters

The sequence in which you develop long-term conditions can have a major impact on your life expectancy. The study found that if you develop diabetes first, followed by psychosis, and then congestive heart failure, you face the most significant loss in life expectancy, about 13 years on average.

Even if you end up with the same conditions, the order can dramatically change your outcome. For example, if you are a 50-year-old man living in an area with average deprivation, your life expectancy could differ by more than 10 years based solely on the sequence in which these diseases emerge.

Risks of Developing Additional Conditions

If you develop diabetes first, then psychosis, and finally congestive heart failure, your risk of either being diagnosed with another serious condition or dying within five years of the last diagnosis is higher.

Interestingly, the study found that having both psychosis and diabetes, in any order, was linked to a longer life expectancy than having psychosis alone. One reason may be that if you have diabetes, you likely have more frequent interactions with healthcare providers, such as through regular diabetic clinic appointments. These touchpoints might improve your overall health outcomes.

The Dangerous Role of Congestive Heart Failure

Congestive heart failure on its own, or in combination with psychosis in any order, was shown to have a negative effect on life expectancy that matched the worst-case scenario of developing all three conditions in the sequence of diabetes, psychosis and congestive heart failure.

Why This Study Matters to You

This was the first study to explore how the order in which you develop multiple long-term health conditions affects your life expectancy. The findings have practical implications for patients like you, as well as for healthcare professionals and policymakers. This knowledge can help guide earlier detection, targeted disease management, and better outcomes both for your personal health and for the healthcare system.

Potential for Better Care and Early Action

This research helps highlight which factors increase your risk of developing long-term conditions. It also points toward potential opportunities for early screening and intervention that could slow disease progression and improve survival rates.

Future Research and Data Quality

You should note that this study used routine health records, which are not always accurate. Some diagnoses may be missed, delayed or poorly recorded. However, ongoing research funded by Health Data Research UK is working to standardize how this data is collected. Over time, this effort will improve the quality of insights drawn from such data.

This approach is not limited to the conditions studied. It could be used to examine other combinations of long-term conditions, including those that follow COVID-19 infection, known as long COVID, and how they impact your quality of life.

Living with Multiple Conditions

If you are dealing with several long-term health conditions, you likely use more healthcare services and medications. You might also struggle more with everyday tasks. These challenges often translate into a lower quality of life and a shorter lifespan.

The study shows that not only the combination of chronic conditions but also the order in which you develop them can significantly affect how long you live. However, this is not always a straightforward relationship. Sometimes, developing additional conditions does not necessarily mean you will live a shorter life.

Your Call to Action for Managing Multiple Long-Term Conditions

You now understand that managing the risk and timing of chronic conditions like diabetes, psychosis and congestive heart failure can significantly influence your life expectancy. To improve your outcomes, make sure to attend regular health checkups, especially if you already live with one or more conditions. Ask your healthcare provider about screening programs that could detect additional risks early. Pay attention to symptoms and follow through with treatment plans. By staying informed and proactive, you can reduce your risk, maintain your quality of life and possibly extend your lifespan.
