Difficulty Lifting 5 Kg? It Could Be a Warning Sign for Your Health
Share
You might think that lifting a 5 kg object—like a grocery bag, a rice sack, or a cat—is no big deal. But for older adults, struggling with this simple task can signal deeper health problems. A new study across 15 countries, including over 51,000 adults aged 50 and older, found that trouble lifting 5 kg is linked to a higher risk of many age-related diseases.
Why Muscle Strength Matters
As we age, our muscle strength naturally declines. This condition, often called sarcopenia, is more than just weakness—it’s a serious health risk. Weak muscles can lead to falls, disability, and lower quality of life. But many tools to measure strength, like handgrip dynamometers, are not always available at home.
That’s why researchers looked at something simpler: Can someone lift 5 kg or not?
What the Study Found
People who reported difficulty lifting 5 kg in 2013 were more likely to develop a range of issues by 2020:
- Low quality of life (17.6% of those with difficulty vs. 5.6% without)
- Depression (16.6% vs. 5.9%)
- Weak handgrip strength (15.7% vs. 4.8%)
- Osteoarthritis (21.2% vs. 13.1%)
- Heart disease, stroke, and Alzheimer’s also showed increased risk
These problems were seen in both men and women, though the risk was often higher for men, especially those over 65.
Why Does Muscle Weakness Lead to Disease?
There are several reasons:
- Less physical activity: Weak muscles often mean a sedentary lifestyle, which is a major risk factor for chronic diseases.
- Inflammation and stress: Ongoing muscle weakness is linked to higher inflammation and oxidative stress in the body—both known to damage organs.
- Muscle = protection: Muscle mass helps the body cope with illness and injury. Without it, recovery becomes harder.
Signs to Watch For
Here are a few signs you—or someone you care about—might be losing muscle strength:
- Struggling to lift everyday items like a grocery bag or water can
- Trouble opening jars or carrying laundry
- Feeling easily tired after short walks or basic chores
These may seem small, but they can be early indicators of bigger health concerns.
What Can You Do About It?
The good news is that muscle strength can often be improved—even in older age:
- Strength training: Light weights, resistance bands, or even bodyweight exercises (like squats and push-ups) help build muscle.
- Protein intake: Eating enough protein from foods like eggs, lentils, fish, and dairy supports muscle repair and growth.
- Stay active: Regular walking, gardening, or dancing helps maintain strength and balance.
If lifting 5 kg feels hard, don’t ignore it. Talk to your doctor and consider getting your handgrip strength tested. It’s a simple way to assess your overall health risk.
The Takeaway
Struggling to lift 5 kg might seem like a small thing—but it can be a big red flag. It’s a quick and easy way to screen for muscle weakness, which is closely linked to many health problems in older adults. Paying attention to this early sign—and taking action—can help you or your loved ones stay healthier and independent for longer.
