Strengthening your bones is not something that can happen overnight, it takes years for your body to build strong bones and even then, it is natural for them to lose their dexterity. All you can do is keep your body healthy to make sure it is prepared for any unexpected situations. For years, many older adults have been told to take vitamin D and calcium supplements to keep their bones strong and prevent falls. However, a new report from U.S. Preventive Services Task Force (USPSTF) is changing that advice. This report suggests that for most older people, these supplements don't actually prevent falls or broken bones. This might be surprising news, we must understand why falls happen more often as we age, what vitamin D and calcium do in the body, and most importantly, what you can do to stay safe and prevent fractures.

What the Report Says

According to the report, vitamin D supplements don't seem to help prevent falls or broken bones for most people over 60. They also found that these supplements, especially with calcium, might increase the risk of kidney stones. This report doesn't mean people with weak bones (osteoporosis), low vitamin D, or who take vitamin D for other health reasons shouldn't take it. It just means that for most healthy older people, these supplements don't prevent falls and fractures.

Why Older People Fall and Break Bones More Easily

There are many reasons why older people are more prone to breaking their bones. Our bones are strongest when we're in our 20s and 30s, and they get weaker as we age so naturally, they can break easily. It can also be harder to move around as we get older, sometimes because of problems like arthritis this can affect how we walk and make us less steady.

There are also different issues like neuropathy, which is a nerve problem that can also make it harder to feel your feet and keep your balance. Eyesight is also a culprit as it can cause you to feel dizzy and fall. Some medicines can also make people feel unsteady, and older people often take more medicines than younger people. Low vitamin D itself can also increase the risk of falls, so keeping vitamin D levels up is still important.

Better Ways To Protect Your Bone Health

USPSTF recommends a few better ways to protect your bone health and prevent broken bones and falls.

Walk Regularly

Regular walks strengthen your muscles and bones, which helps you stay steady on your feet. It is as simple as practice makes perfect so the more you walk, the better it is. Walking also improves your balance, making you less likely to fall.

Do Strength Training

Strength training, like lifting weights or using resistance bands, makes your bones stronger and helps prevent fractures if you do fall. It is like a safety cushion, but you must be careful while doing so because it can lead to injuries if done too much.

Practice Balance

Activities like tai chi, Pilates, and yoga can improve your balance and coordination, making you more stable and less prone to falls. These can also help you improve your muscle flexibility and strength that in turn helps your body be stronger.

Check Your Medicines

If you have osteoporosis, talk to your doctor about medications that can help strengthen your bones and lower your risk of fractures. Many medications can also have unsavory side effects like weakened joints, losing muscle strength, etc.

Eat Enough Protein

A proper diet goes a long way when it comes to your entire body health. So to keep up with your body’s nutrition and muscle health, eat more protein along with a balanced meal that includes loads of fiber, healthy fats and carbs.

Get Your Eyes Checked

Having poor eyesight can be difficult, not only does it make life difficult without glasses, but it also increases the possibilities of getting into minor accidents like bumping into people and missing objects placed in front of us.

Get Enough Sleep

Getting enough sleep is also important because when you are not sleeping, you get disoriented and can ignore even obvious things like the last stair in the staircase. Make sure you get enough sleep to keep you fresh and focused.

Make Your Home Safe

There are many things that can cause you to have accidents, even in your home. To avoid such falls, make sure there are no lose ends like crooked floor panels, rugs that are sticking out or protruding furniture that can hurt your knees

NBC News producer Susan Kroll, 58, initially attributed her occasional difficulty remembering words to menopause-related brain fog. However, tests revealed an elevated genetic risk of Alzheimer’s disease and abnormal amyloid levels in her brain.

Her journey began when she sought a diagnosis for her mother, who had started experiencing memory problems at 75. While helping her mother, Kroll decided to investigate her own risk after learning that Alzheimer’s risk can be genetic, she wrote on Today.com.

Genetic Testing Revealed An Elevated Alzheimer’s Risk

Testing showed that Kroll’s mother carried two copies of a gene called APOE4. Everyone inherits one APOE gene from each parent. The three common variants are APOE2, which may reduce Alzheimer’s risk; APOE3, the most common variant, which has a neutral effect; and APOE4, which increases the risk.

According to the Mayo Clinic, people with two copies of APOE4 are eight to 12 times more likely to develop Alzheimer’s.

To understand her own risk, Kroll took a cheek-swab genetic test in October 2024.

"I had an APOE4 and APOE3 gene, making me two to three times more likely to develop Alzheimer’s. I was a bit relieved," Kroll wrote.

Blood Tests And Brain Scans Revealed More

In May 2025, Kroll took a blood test developed to help diagnose Alzheimer’s disease, which had recently been cleared by the US Food and Drug Administration (FDA).

The test measures certain proteins, including a specific form of tau, that can indicate the presence of amyloid plaques in the brain. These protein deposits are considered a hallmark of Alzheimer’s disease.

Kroll said her "results were well outside the normal range". She had also noticed occasional difficulty remembering words, which she had initially attributed to menopause-related brain fog.

She was given personalised recommendations covering diet, exercise, supplements and sleep.

Diet, Exercise And Sleep Changes To Support Brain Health

Kroll made several changes to her daily routine.

"I cut out artificial sweeteners and limited fried and processed foods, red meat, cheese, sweets and alcohol. Every day, I started eating leafy greens, whole grains, veggies and fruit, and every week multiple servings of fish, walnuts, almonds, avocado and berries."

She also intensified her workouts, doing 45–60 minutes of cardio three to four days a week, alongside strength training. She focused on three muscle groups, completing three sets of each exercise with eight to 10 repetitions. She also started going to bed earlier.

Kisunla Infusions Reduced Amyloid Levels In Her Brain

In December 2025, Kroll began treatment with Kisunla, an anti-amyloid infusion approved by the FDA in 2024.

A previous brain scan had shown elevated amyloid levels in every quadrant of her brain. Clinical trials have shown that Kisunla can slow cognitive and functional decline in eligible patients.

After six infusions, Kroll underwent another brain scan in May 2026 to assess her progress.

Her amyloid score dropped from 86 to four. The radiologist noted, "The amyloid issue has resolved."

Further blood tests showed that her tau levels were normal. Kroll suggested that her dietary changes may have contributed to this result.

Does She Still Have An Elevated Alzheimer’s Risk?

Kroll currently has neither Alzheimer’s disease nor mild cognitive impairment. However, she continues to have positive biomarkers and an elevated genetic risk. She believes the "early interventions helped slow down or potentially stop the progression of changes years before they could worsen".

Her journey is far from over. She continues to receive care at the Alzheimer’s Prevention Clinic, where her blood and biomarkers are monitored monthly.

Obesity drugs such as semaglutide and tirzepatide may offer benefits beyond weight loss and blood sugar control. Researchers say these medicines could also help protect brain function, including memory and other cognitive abilities.

Researchers from the University of Gothenburg and the University of Copenhagen examined evidence on how these drugs affect the brain and their potential to inform treatments aimed at preserving cognitive function. The review was published in the journal Science.

How Do Obesity Drugs Affect The Brain?

Semaglutide and tirzepatide belong to a class of medicines that act on metabolic pathways involved in appetite and blood sugar regulation. They may also influence biological processes important for brain function.

Animal studies suggest that GLP-1 drugs can affect learning and memory. However, findings from human studies have been mixed.

Studies analysing patient records have linked GLP-1 treatment to a lower risk of dementia among people with type 2 diabetes. However, these findings do not establish whether the medicines themselves are responsible for the reduced risk.

Semaglutide Failed To Slow Alzheimer's Progression

The potential benefits of these drugs have also been examined in people with Alzheimer's disease.

In Novo Nordisk's EVOKE and EVOKE+ clinical trials, semaglutide did not slow disease progression in patients with early Alzheimer's disease, despite producing changes in several biological markers associated with the condition.

However, researchers say these findings do not rule out potential benefits in other groups of patients.

People with obesity or type 2 diabetes may experience difficulties with attention, planning and processing speed. These cognitive problems are often associated with metabolic and vascular health, making them potential targets for treatment.

Stina Börchers, first author of the review and a researcher affiliated with the University of Gothenburg and the University of Copenhagen, said it is important to establish whether these treatments can help preserve cognitive abilities, particularly when started before problems become established.

“We need to find out whether these treatments can help people with obesity or diabetes preserve their cognitive abilities, particularly if treatment begins before cognitive problems become established,” Börchers said.

Could Obesity Drugs Lead To New Brain Treatments?

Researchers are trying to understand whether the potential effects of obesity medicines on the brain result from improved metabolism, direct action on the brain, or a combination of both.

Christoffer Clemmensen, senior author of the review and research group leader at the University of Copenhagen, said advances in obesity medicines offer new opportunities to understand how metabolic regulation influences brain function.

“By disentangling the direct and indirect effects of these drugs on the brain, we may ultimately be able to develop treatments specifically aimed at preserving cognitive function,” Clemmensen said.

Why More Clinical Trials Are Needed

The researchers are calling for clinical trials that assess memory and other cognitive abilities from the beginning of treatment.

They also stress the need to monitor older and frail patients. Rapid weight loss and loss of muscle mass could affect physical function and potentially reduce the benefits of treatment in these groups.

For now, whether obesity drugs can help preserve cognitive function remains an important research question. More clinical evidence is needed before they can be considered treatments for protecting brain health.

For 25-year-old Kaela Knight, a nail artist from Colorado, taking tirzepatide, the active ingredient in Eli Lilly's Mounjaro and Zepbound, brought an unusual side effect: skin so sensitive that even a light touch hurt.

Knight started treatment in September 2024 at 210 pounds and eventually reached 125 pounds. But during her second month, as her dose increased from 2.5 mg to 5 mg, she began experiencing burning sensations.

"I always describe it as feeling like a sunburn without any visible redness or irritation," she told the Daily Mail.

The sensation affected her hips, forearms and neck. Episodes lasted 24–48 hours, although some persisted for about a week.

Other patients taking Novo Nordisk's Ozempic and also Mounjaro have reported similar experiences.

Known as allodynia, this nerve-pain condition makes normally harmless sensations, such as clothing brushing against the skin or a light touch, painful. Patients describe it as a sunburn without visible redness or irritation.

Although it is not an established side effect of Ozempic, Wegovy, Mounjaro or Zepbound, medical reports have documented similar symptoms. A direct link remains unproven.

"I have [areas] all over that are burning. It's driving me nuts," one Reddit user wrote. Another said painkillers and lidocaine gels offered little relief.

Some patients report improvement after reducing their dose or stopping treatment.

Why Could Weight-Loss Injections Cause Burning Skin?

Semaglutide, used in Ozempic and Wegovy, mimics the GLP-1 hormone. Tirzepatide, used in Mounjaro and Zepbound, targets GLP-1 and GIP receptors.

Dr Richard Siegel, an endocrinologist at Tufts Medicine, told the Daily Mail that these drugs could potentially affect nerve signalling through the brain and spinal cord.

Another theory involves changes in the fat layer beneath the skin during weight loss, which could affect nerve sensitivity. Neither explanation has been proven.

What Do Medical Reports Reveal?

An October 2025 report documented two cases:

• A 56-year-old woman developed painful skin sensations after switching to semaglutide 2.4 mg. Symptoms resolved without treatment after six weeks.
• A 75-year-old man with type 2 diabetes developed widespread burning after switching to tirzepatide. Symptoms resolved after he discontinued it and returned to oral semaglutide.

Some patients report improvement over time or after reducing their dose.

Dr Siegel said symptoms can last days to weeks, potentially becoming less noticeable as the body adjusts to treatment, much like nausea and constipation.

"It's possible something similar is happening here, where temporary changes in receptor activity alter nerve signaling at first, but become less noticeable as the body adjusts," he said.

Newer Weight-Loss Drugs May Carry A Higher Risk

Clinical trials have also recorded dysesthesia, a broader category of abnormal sensations, including burning and tingling. It is not necessarily the same as allodynia.

In a high-dose oral semaglutide trial, dysesthesia occurred in fewer than 3% of 334 participants, compared with none receiving placebo.

Phase 3 trials of retatrutide, an experimental drug targeting GLP-1, GIP and glucagon receptors, reported:

• 9 mg dose: 8.8%
• 12 mg dose: 20.9%
• Placebo: 0.7%

Who Is More Vulnerable To Allodynia?

Risk factors remain unclear. Dr Siegel believes higher doses could play a role.

"As best as I can tell, it would mostly be people on higher doses of these medications," he said.

He also suggested that people with greater pain sensitivity, including those with fibromyalgia, might be more susceptible.

What Should Patients Do?

Patients experiencing unusual skin burning or sensitivity should consult their doctor. Dose adjustments or alternative treatments may be considered, but medication should not be changed or stopped without medical advice.

Allodynia can also occur with shingles, migraines and nerve damage, so symptoms should not automatically be attributed to weight-loss drugs.

Dr Siegel recommends recording when symptoms occur, where they appear and what makes them better or worse.

Persistent or worsening pain should be medically evaluated.
