Q: My grandmother is losing balance and falling very frequently. She is hurting herself because of this. What are the reasons and how can she avoid falling?

Krishna: Falling down is one of the problems old people face very often. Balance problems in older adults occur when the brain struggles to process signals from the inner ears, eyes, muscles, and joints.

 Older adults also fall frequently due to a combination of physical weakness, balance and vision changes, medication side effects, chronic medical conditions, and home hazards.

Moreover because of joint problems they cannot lift their legs high enough to avoid obstacles in their path like stones and  uneven ground surfaces.

From a biological perspective, hurdles or abnormalities in walking (known as gait disorders) are typically caused by disruptions in one of three interconnected body systems:

Musculoskeletal System (Pain and Weakness): Conditions like arthritis, joint inflammation, muscle strains, or bone fractures cause an "antalgic gait" (limping). The body alters its natural stride to avoid putting weight on a painful limb. 

Neurological System (Signal Disruption): Diseases such as Parkinson's disease, multiple sclerosis (MS), or a stroke disrupt the brain's ability to send automatic movement signals to the legs. For instance, Parkinson's can cause "freezing," where a person's feet feel physically glued to the ground.

Sensory System (Lack of Feedback): Peripheral neuropathy (nerve damage often caused by diabetes) numbs the feet. Because the brain cannot properly feel the ground, it becomes incredibly difficult to maintain balance, leading to tripping or an unsteady, cautious stride.

Other common causes

Inner ear and vestibular disorders: Conditions like Benign Paroxysmal Positional Vertigo (BPPV), Ménière's disease, or labyrinthitis disrupt spatial orientation.

Muscle weakness and joint stiffness: Age-related loss of leg and core strength makes it hard to recover from a stumble. 

Vision changes: Decreased depth perception, cataracts, or poor peripheral vision make misjudging steps common. 

Blood pressure drops: Postural hypotension causes sudden dizziness or lightheadedness when standing up quickly.

Medications: Side effects from sedatives, blood pressure pills, antidepressants, or taking five or more drugs at once can cause unsteadiness. 

Neurological conditions: Stroke, Parkinson's disease, or peripheral neuropathy impair nerve signals to the feet and brain.

Size of feet: Small feet on their own are not a direct medical cause of falls, though disproportionately small feet relative to body height and weight or structural foot problems can influence balance and stability. 

How foot size and structure affect balance
Base of support: Smaller feet create a smaller base of support on the ground, which can slightly increase postural sway compared to larger feet in biomechanical studies. [1]
Ankle strategy: Research indicates that smaller or normalized foot sizes can alter how people use ankle-adjustment strategies to maintain balance. [1]
Anecdotal reports: Some taller individuals with smaller feet say it affects their centre of gravity and coordination, while others report no balance issues at all. [1]
What actually causes foot-related falls
Falls are rarely caused by the physical size of the foot itself. Instead, functional and medical foot factors play a much larger role:
Muscle weakness: Weak plantar muscles or toe flexors reduce your ability to grip the ground and stabilize your stance.
Loss of sensation (Neuropathy): Conditions like diabetes or nerve damage reduce feedback from the feet to the brain regarding body position.
Structural issues: Conditions such as flat feet (pes planus), high arches, bunions, or excessive foot rotation affect shock absorption and gait.
Pain and footwear: Foot pain or poorly fitted, unsupportive shoes alter how you walk and increase trip hazards.
The primary causes are divided into physical, medical, and environmental factors:
Physical and biological changes
Muscle weakness (Sarcopenia): Older adults naturally lose muscle mass and strength, particularly in the legs and core, which makes it harder to support the body or react quickly to catch oneself after a trip.
Balance and gait impairments: Aging affects the inner ear, reflexes, and the brain's ability to coordinate movement, leading to a wider stance, shuffling feet, and unsteadiness.
Vision and hearing loss: Conditions like cataracts, glaucoma, or reduced depth perception make it difficult to spot or judge step changes, curbs, or indoor hazards.
Postural hypotension: Blood pressure can drop suddenly when standing up from a chair or bed, causing dizziness, lightheadedness, or fainting. 
Medical and medication factors
Polypharmacy (multiple medications): Taking four or more medications—especially sedatives, antidepressants, blood pressure drugs, or sleep aids—greatly increases the risk of drowsiness, confusion, and poor balance.
Chronic health conditions: Illnesses such as Parkinson’s disease, stroke, arthritis, peripheral neuropathy (numbness in the feet), and dementia impair physical control and spatial awareness.
Foot problems: Corns, bunions, insensitive feet, or wearing loose slippers instead of supportive shoes reduce stability. 
Environmental hazards
Home obstacles: Most falls happen indoors, triggered by loose throw rugs, poor lighting (especially at night), cluttered walkways, and lack of grab bars in the bathroom.
Road obstacles: Uneven road/earth surfaces, stones and other hurdles, slippery surfaces, speed bumps and cushions, and rumble strips.

Symptoms of the health conditions

Teetering, wobbling, or staggering while walking

A spinning sensation (vertigo) or feeling lightheaded

Blurry vision, confusion, or general fatigue

Frequent stumbles or falls

Solutions , exercises and medical evaluation: Consult a doctor or specialist to review medications, check blood pressure, and test inner ear or nerve function.

Vestibular or physical therapy: Targeted head and body movements retrain the brain to process balance signals.

Strength and balance routines: Practice safe exercises like Tai Chi, yoga, sit-to-stand movements, or single-leg stands next to a sturdy chair.

Home safety upgrades: Remove loose rugs and electrical cords, install handrails in hallways and bathrooms, and keep living spaces brightly lit.

Wearing  proper footwear: Wear low-heeled, well-fitted shoes with non-skid soles. 

Helping old people with walking aids. 

Choosing the right walking aid depends on the senior's balance, strength, and whether they need support indoors or outdoors

Types of Walking Aids
Canes and Walking Sticks: Best for mild balance issues or weakness on one side. Single-point canes offer basic support, while tripod or quad canes (four-legged bases) provide extra stability.
Standard and Folding Walkers: Best for moderate balance problems or low endurance. They have four contact points (or two front wheels) and require lifting or pushing slightly with each step.
Rollators (Walkers with Wheels): Ideal for outdoor use, longer distances, or people who get tired easily. They feature four wheels, handbrakes, a built-in seat for resting, and a storage basket. 
Upright Walkers: Designed with forearm supports to take pressure off the wrists and lower back, making them helpful for seniors with arthritis. 

If possible, hold your grandmother's hand while she is getting up and  walking whenever you are around. She will feel very happy if you help her balance herself.
