Growing older brings wisdom, experience, and new opportunities to enjoy life. While aging naturally increases the risk of certain health conditions, many of the leading causes of death after age 75 are influenced by lifestyle choices, preventive care, and early treatment. Although no one can eliminate risk entirely, healthy habits can significantly improve both longevity and quality of life.
Here’s a closer look at five of the most common causes of death in older adults and practical steps that may help reduce your risk.

Healthy Habits That Can Make a Difference
While aging cannot be stopped, healthy choices can help reduce the risk of many chronic diseases.
Stay Active
Aim for regular physical activity, including aerobic exercise, strength training, balance exercises, and stretching, as recommended by your healthcare provider.
Eat a Nutritious Diet
Focus on:
- Fruits and vegetables
- Whole grains
- Lean proteins
- Healthy fats such as those found in nuts, seeds, and olive oil
- Adequate hydration
Prioritize Sleep
Most older adults benefit from about 7–8 hours of quality sleep each night.
Keep Up With Preventive Care
Routine health screenings and vaccinations can help detect problems early and prevent serious illness.
Manage Chronic Conditions
If you have high blood pressure, diabetes, or high cholesterol, following your treatment plan can greatly reduce your risk of complications.
Stay Connected
Maintaining strong social relationships and engaging in meaningful activities can support both mental and physical well-being.
The Importance of Regular Checkups
Regular visits with your healthcare provider can help identify health concerns before they become serious. Screening tests, medication reviews, and discussions about lifestyle changes are all important parts of healthy aging.
Final Thoughts
The claim that “99% of deaths after age 75 are due to these five causes” is not accurate. While heart disease, cancer, stroke, chronic respiratory diseases, and Alzheimer’s disease are among the leading causes of death in older adults, they do not account for 99% of deaths. Other conditions—including infections, kidney disease, accidents, and many other illnesses—also contribute.
The encouraging news is that many risk factors for these major diseases can be reduced through healthy eating, regular exercise, avoiding tobacco, managing chronic conditions, staying socially engaged, and receiving appropriate preventive care. Small, consistent lifestyle choices can have a meaningful impact on health and independence in later years.
