Age-related changes in the musculoskeletal system can significantly impact mobility, posture, and overall quality of life, but many related problems can be delayed or managed with appropriate care, according to Dr. Maha Al Naemi, senior consultant in Family Medicine and Wellness Centre in-charge at Muaither Health Centre under the Primary Health Care Corporation (PHCC).
The musculoskeletal system, which comprises bones, muscles, joints, cartilage, ligaments, tendons, and connective tissues, naturally undergoes deterioration as people age. Dr. Al Naemi explained that bone density declines due to a loss of calcium and minerals, a process that is particularly pronounced in women after menopause, increasing the risk of fractures. The spine is also affected as intervertebral discs lose fluid and thin, which can lead to a reduction in height, spinal curvature, and development of bone spurs.
Joints tend to become stiffer and less flexible with age because of decreased synovial fluid and cartilage degeneration, sometimes coupled with mineral buildup. These changes often manifest in weight-bearing joints such as hips and knees and can result in pain, swelling, and reduced range of motion. Osteophytes, or bony enlargements, are also common in finger joints. Collectively, these conditions contribute to osteoarthritis, the most prevalent form of arthritis among older adults.
Muscle mass and strength diminish over time as muscle tissue is lost more rapidly than it is replaced, often accompanied by fat infiltration within muscles. This decline can cause slower, less efficient movement and difficulties with everyday tasks such as climbing stairs or carrying objects. Posture and gait may also change, while balance impairment and muscle weakness elevate the risk of falls—an important concern due to the heightened fragility of bones in older individuals.
Osteoporosis, often called a “silent disease” because it may remain asymptomatic until fractures occur, is among the most common musculoskeletal disorders affecting seniors. Compression fractures in the spine can lead to back pain, height loss, and limited mobility. Symptoms signaling musculoskeletal issues include persistent joint or back pain, swelling, stiffness, bone fractures from minor trauma, reduced ability to perform daily activities, and changes in posture.
Dr. Al Naemi emphasized the importance of adopting healthy lifestyle practices to support musculoskeletal health. Regular physical activity, especially exercises that enhance resistance, balance, and flexibility, can help maintain muscle strength, improve balance, and protect bone health, thereby lowering fall and fracture risks. Adequate nutrition plays a key role as well, with calcium and vitamin D essential for bone maintenance, and sufficient protein intake necessary to preserve muscle mass and strength. Dietary recommendations generally suggest 0.8 to 1.0 grams of protein per kilogram of body weight daily, adjusted for individual health conditions.
Fall prevention strategies should include assessments of balance, gait, vision, footwear, home safety, medication use, vitamin D status, and nutritional intake. Older adults who have experienced falls or feel unsteady are advised to consult medical professionals for evaluation.
Dr. Al Naemi urged those experiencing persistent joint pain, sudden back pain, posture changes, recurrent falls, or mobility difficulties to seek timely medical advice. Because osteoporosis can remain undetected until a fracture occurs, routine screening is particularly important for individuals at elevated risk. Medical management may involve bone density testing, fall-risk assessment, physiotherapy, nutritional counseling, personalized exercise programs, and appropriate treatment for conditions such as osteoporosis and osteoarthritis.
In conclusion, while aging naturally affects the musculoskeletal system, many adverse effects can be prevented or mitigated with early intervention, a balanced diet, regular exercise, fall prevention, and prompt medical care, helping older adults maintain their independence and quality of life.
