After a Fall: The Medical Checks That Help Prevent the Next One

Why a Thorough Assessment After a Fall Matters

When an older person falls, the natural response is to check for injuries — and that matters. But one of the most powerful ways to prevent future falls is something that often gets overlooked: a careful medical evaluation that looks for why the fall happened in the first place. This article exists to explain that evaluation. Because busy clinicians who are not specialists in older-adult care may not always carry out a thorough work-up unless someone asks, knowing what should be checked allows older adults and their families to be politely proactive and ensure nothing important is missed. The goal is not just to treat an injury but to reduce the chance of the next fall, so that an older person can stay as healthy, active, and independent as possible.

Falls are common in later life, and at a minimum they are frightening and embarrassing, sometimes enough to keep an older person from going out as much as they otherwise would. They can also be genuinely dangerous — a broken hip or another major fall can be a life-changing event that threatens not only health but independence.

There are two particular reasons that specialists in older-adult care focus so closely on falls. First, a fall can be a sign of a new and serious medical problem, and sometimes it is the only obvious sign anyone notices; an older person may become weak and fall because of dehydration or a serious infection, for example. Second, an older adult who has fallen is at much higher risk of falling again, which makes the period right after a fall an especially important window for prevention.

1. Assess for a New Underlying Illness

The first step is to look for a new health problem that could have made the person weak and brought on the fall. There is a long list of possibilities, including infections such as a urinary tract infection or pneumonia, dehydration, anemia (a low red blood cell count), a heart problem such as a minor heart attack or an irregular rhythm that has gotten out of control, or even a stroke.

One important caution applies here. A clinician must first recognize that the older person is weaker or more confused than usual — and they should not be left to assume this. Health providers sometimes see an older person arrive weak and confused and assume that is simply how they always are, a form of age-based bias that does occur. Families can help by clearly stating that this presentation is different from the person's normal baseline. The clinician checks for new illness through a history (asking when the weakness or symptoms began and what accompanies them) and a physical examination, often followed by relevant laboratory tests.

2. Check Blood Pressure and Pulse Sitting and Standing

A key check is measuring blood pressure and pulse both while sitting and after standing. This is especially important when falls are linked to standing up, lightheadedness, or fainting, and when the person takes blood pressure medication or another drug that can lower blood pressure — certain prostate medications, for instance, are known to drop blood pressure when a person stands.

This check matters because of a very common condition called orthostatic, or postural, hypotension — a drop in blood pressure on standing. In younger people, the body quickly tightens the blood vessels in the legs when standing so that enough blood continues reaching the head. With age, this compensating system becomes slower, allowing blood pressure to fall for a short time after standing, during which a person can become weak, dizzy, and fall, risking a head injury or fracture. Despite its importance, this simple test is often skipped; one study of older patients seen in the emergency room after fainting found that checking blood pressure sitting and standing was the most useful test performed, yet it was done only about a third of the time. If blood pressure drops significantly on standing — or is generally low while sitting — it may be wise to dial back medications that affect blood pressure, and older adults can also be taught to stand up slowly and hold onto something steady at first.

3. Check Certain Blood Tests

Some contributors to falls show up only in blood work, so checking certain laboratory tests is worthwhile, particularly if the person seems unwell or has not had labs in a while. Common findings include anemia and abnormal blood sodium, either too high or too low — the latter being a known side effect of certain medications. A complete blood count along with a check of electrolytes and kidney function is generally a sensible starting point, with the specific tests depending on the person's circumstances and medical history.

Older adults on diabetes medications should be checked to make sure their blood sugar is not frequently dropping too low, since low blood sugar can also cause falls. Because blood pressure and blood sugar may look normal during a brief clinic visit, reviewing home logs or data from a continuous glucose monitor can be necessary. It is a good idea to keep a copy of lab results, note anything flagged as high or low, and ask the clinician to explain any abnormalities, whether they might relate to falls, and what will be done about them.

4. Review Medications Associated With Falls

Many older adults take medications that increase the risk of falling, and the encouraging news is that these can often be reduced or eliminated. This is so central to fall prevention that public health guidance recommends every older adult who has fallen request a medication review.

Several categories deserve particular attention. First are medications that affect memory and slow brain function — sedatives, tranquilizers, and sleeping pills (including over-the-counter ones), antipsychotics used in people with dementia, and a broad group of drugs known as anticholinergics. Opioid pain medications, especially if recently started, are also worth reviewing. So are medications for blood pressure and diabetes, because falls can be linked to blood pressure or blood sugar running a little too low; in practice, some older adults are treated more aggressively for these conditions than is strictly necessary for their age and health. A careful review can often find safe opportunities to simplify a medication list.

5. Check Gait, Balance, and Leg Strength

A clinician should carefully watch how the older person walks — "gait" is the medical term — and, better still, perform a few simple tests of strength and balance. A quick way to assess leg strength is to have the person sit in a chair, fold their arms across their chest, and try to stand without using their arms; those who cannot almost certainly have reduced leg strength and would benefit from a strengthening program.

Balance can be assessed with a simple four-stage test, in which the person tries to hold each of four positions for ten seconds without holding onto anything: feet together side by side; one foot moved halfway in front of the other; one foot placed directly in front of the other; and finally standing on a single foot. Many older adults who are falling struggle with the later stages, indicating they could benefit from balance exercises. If gait, strength, or balance appear impaired, the clinician should first check whether pain or discomfort — severe arthritis in the hips or knees, for example — is contributing, and then refer the person to physical therapy. Physical therapy is an excellent resource: therapists can evaluate walking, balance, and strength in detail; certain physiotherapy exercises have been shown in clinical trials to reduce falls in people with poor strength and balance; and they can fit a person for an appropriate assistive device such as a cane or walker.

6. Evaluate for Underlying Cardiac or Neurological Conditions

Beyond new, acute illnesses, some older adults fall because of a chronic condition affecting the heart or nervous system. On the heart side, conditions that make the heart beat too slowly can cause weakness and falls; some of these are treatable with a pacemaker, after which a person may feel much better and fall less. On the neurological side, chronic conditions such as nerve damage in the feet (neuropathy) or neurodegenerative diseases like Parkinson's disease can affect balance.

It is especially worth asking about these possibilities when falls or near falls keep happening — particularly after risky medications have already been minimized and after blood pressure has been confirmed not to be over-treated. Families can simply ask whether a heart condition or an underlying neurological condition might be contributing.

7. Check for Osteoporosis and Fracture Risk

Osteoporosis — thinning, more brittle bones — is not itself a cause of falls, but it is a major reason a fall can cause serious harm, since fragile bones are far more likely to break in a hip or other fracture. Because anyone who has fallen is at higher risk of falling again, it is important to make sure they have been screened for osteoporosis even if nothing broke this time.

Screening is a standard preventive recommendation — every woman should be screened at least once after age 65 — but many have not had it done, so it is worth checking. Osteoporosis should not be overlooked in men, and screening is also recommended for an older person of any gender who falls and fractures something. Notably, research shows that people who fall and fracture a bone often do not receive evaluation and treatment for underlying osteoporosis, which is a missed opportunity, because treatment has been shown to be effective and safe. It can even begin soon after a fracture; while clinicians once worried that early treatment might disrupt healing, randomized trials have found that starting treatment promptly does not appear to interfere with fracture healing.

8. Consider Vision, Podiatry, and Home Safety Referrals

Finally, it is worth considering whether referrals for vision care, foot care (podiatry), or a home safety assessment might be appropriate and available. Whether each fits depends on the situation, but it costs nothing to ask. Home safety assessments, often carried out by occupational therapists, can be especially valuable for identifying and removing hazards in the home, though they are not always covered by insurance. Where a professional home evaluation is not available, well-designed home safety self-assessment tools can help a person and their family review their own environment.

Being Politely Proactive

The thread running through all eight checks is that thoroughness after a fall often depends on someone asking for it. Most clinicians have the best of intentions, but research shows older patients frequently do not receive all the recommended care, partly because a proper assessment takes time and attention that a rushed visit may not allow. Even when a fall seems to have been "just a trip," it is reasonable to ask about these eight areas — new illness, blood pressure on standing, blood tests, medications, gait and balance, heart and neurological conditions, bone health, and helpful referrals. Approaching the conversation politely but proactively helps ensure that a fall becomes the starting point for prevention rather than a missed opportunity, protecting the health and independence that matter most.
