Rapid Weight Loss in Older People: A Concerning Sign

Unexplained rapid weight loss in older people can be a sign of underlying disease and is associated with an increased risk of falls, fractures, and a poorer long-term prognosis. Rapid weight loss is defined as a more than five percent decrease in body weight within a 12-month interval over five years. This alarming health issue is now found to be linked with abdominal aortic calcification (AAC), a marker of advanced blood vessel disease.

New research by Edith Cowan University found that AAC is linked to a higher risk of rapid weight loss in older women. This study of 929 older women discovered that AAC was associated with a higher likelihood of rapid weight loss, increasing the risk of fractures, falls, and other health complications. AAC is a marker of advanced blood vessel disease and can limit blood flow to the gut, affecting nutrient absorption.

The Implications of Rapid Weight Loss

Rapid weight loss is associated with a 49 percent increase in the risk of dying in the next 9.5 years. This risk increases to 87 percent in women who experience rapid weight loss of more than ten percent in a 12-month interval. These figures indicate that unexplained weight loss in older people, particularly in women, carries significant health implications. Unintentional weight loss is also associated with an increased risk of cancer diagnosis in older adults, particularly upper gastrointestinal cancers.

Traditional Approaches May Not Help

Moderate to extensive AAC was linked to a 36 percent and 58 percent higher likelihood of rapid weight loss, even after adjusting for dietary factors, blood pressure, and cholesterol. The study suggests that traditional approaches to increasing protein and energy intake may not help with body composition if vascular disease is driving the weight loss. This finding suggests the need for a shift in our approaches to managing weight loss in older women, particularly those with AAC.

AAC: A Tool for Risk Assessment

Abdominal aortic calcification may be a tool to identify older women with the highest risk of rapid weight loss. It presents an opportunity for cardiovascular disease risk screening. By identifying and understanding AAC's role in rapid weight loss, healthcare providers can better manage weight loss in older women and potentially prevent the associated risks. However, further research is needed to replicate these findings in other cohorts and to study blood flow measures and macronutrient absorption.

Conclusion

In conclusion, unexplained rapid weight loss in older women can be a sign of serious underlying health issues, including advanced blood vessel disease marked by AAC. Traditional approaches to managing weight may not be effective if vascular disease is driving the weight loss. AAC presents a potential marker for identifying women at high risk, leading to targeted cardiovascular disease risk screening. It reinforces the need for increased awareness and research into the health implications of rapid weight loss in older women.
