Because there are typically no symptoms until the first fracture occurs, osteoporosis is considered a silent disease. Some call it a silent killer.

Osteoporosis is a bone disease characterized by decreased bone density and strength, leading to fragile, brittle bones that increase the risk of fractures, especially in the spine, hips and wrists.

The National Osteoporosis Foundation estimates that more than 10 million Americans have osteoporosis. Another 43 million have low bone mass, which is the precursor to osteoporosis. By 2030, the number of adults with osteoporosis or low bone mass is estimated to increase by more than 30%, to 71 million.

The reasons for the increase include lifestyle issues, particularly smoking, lack of physical activity and alcohol abuse. Our aging population, along with the insufficient attention paid to this disease, are also why osteoporosis is on the rise.

If you are older, it may be discouraging to read those statistics. But as orthopedic specialists who have studied this disease, we know that osteoporosis is not inevitable. The key to healthy bones for a lifetime is to take some simple preventive measures – and the earlier, the better.

Although the symptoms are not obvious early on, certain signs will indicate your bones are becoming weaker. The most serious complications of osteoporosis are fractures, which can to chronic pain, hospitalization, disability, depression, reduced quality of and increased mortality. Worldwide, osteoporosis causes nearly 9 million fractures annually. That’s one osteoporotic fracture every three seconds.

Height loss, back pain

Minor bumps or falls may lead to fractures, especially in the hip, wrist or spine. These types of fractures are often the first sign of the disease.

If you notice that you’re getting shorter, the cause could be compression fractures in the spine; this too is a common symptom of osteoporosis.

Although it’s typical for most people to lose height as they age – about 1 to 1½ inches (2.5 to 3.8 centimeters) over a lifetime – those with osteoporosis who have multiple spinal fractures could lose 2 to 3 inches or more in a relatively rapid time frame.

Curved posture, or noticeable changes in posture, may lead to a hunched back, which could be a sign that your spine is weakening and losing density.

Persistent back pain is another indicator – this too is the result of tiny fractures or compression of the spine.

A healthy diet and exercise are two ways to build up bone density.

Calcium and vitamin D

Osteoporosis cannot be completely cured, but certain lifestyle and dietary factors can lower your risk.

Calcium and vitamin D are essential for bone health. Calcium helps maintain strong bones, while vitamin D assists in calcium absorption. Women over age 50 and over 70 should consume at least 1,200 milligrams of calcium daily from food and, if necessary, supplements.

The easy way to get calcium is through dairy products. Milk, yogurt and cheese are among the richest sources. One cup of milk provides about 300 milligrams of calcium, one-fourth of the requirement. If you are vegan, calcium is in many plant-based foods, soy, beans, peas, lentils, oranges, almonds and dark leafy greens.

Adults should aim for two to three servings of calcium-rich foods daily. Consuming them throughout the day with meals helps improve absorption.

Vitamin D is obtained mostly from supplements and sunlight, which is the easiest way to get the recommended dose. Your body will produce enough vitamin D if you expose your arms, legs and face to direct sunlight for 10 to 30 minutes between 10 a.m. and 3 p.m., two to three times a week.

Although it’s best to wear short-sleeve shirts and shorts during this brief period, it’s okay to wear sunglasses and apply sunscreen to your face. Sunlight through a window won’t have the same effect – glass reduces absorption of the UV rays needed for vitamin D production. People with darker skin, or those living in less sunny regions, may need more sunlight to get the same effect.

If a doctor has given you a diagnosis of osteoporosis, it’s possible the calcium and vitamin D that you’re getting through food and sun exposure alone is not enough; you should ask your doctor if you need medication.

Chickpeas, sesame seeds and dark green vegetables, such as kale, arugula and broccoli, are good sources of calcium.

Dance, jog, lift weights and avoid alcohol

Regular exercise is an excellent activity that can help stave off osteoporosis. Weight-bearing exercises, such as brisk walking, jogging and dancing, are great for increasing bone density. Strength , such as lifting weights, helps with stability and flexibility, which reduces the risk of falling.

Aim for 30 minutes of weight-bearing exercise at least four days a week, combined with muscle-strengthening exercises at least twice a week.

Particularly for women, who lose bone density during and after menopause, regular exercise is critical. Working out prior to menopause will reduce the risk of osteoporosis in your later years.

And avoid harmful habits – smoking and heavy alcohol consumption can weaken bone density and increase the risk of fractures.

Fall prevention strategies and balance training are crucial and can help reduce the risk of fractures.

Screening and treatment

Women should start osteoporosis screening at age 65, according to the U.S. Preventive Services Task Force. Men should consider screening if they have risk factors for osteoporosis, which include smoking, alcohol use disorder, some chronic diseases such as diabetes, and age. Men over 70 are at higher risk.

Medical imaging such as a bone density scan and spinal X-rays can confirm osteoporosis and detect compression fractures. These basic tests, combined with age and medical history, are enough to make a clear diagnosis.

Managing osteoporosis is a long-term that requires ongoing commitment to lifestyle changes. Recognizing the early warning signs and making these proactive lifestyle changes is the first step to prevent the disease and keep your bones healthy.The Conversation

I’m a Muslim immigrant and a psychiatrist living in Michigan – I haven’t decided how to vote yet

Published

theconversation.com – Farha Abassi, Assistant Professor of Psychiatry, Michigan – 2024-11-04 07:49:00

Farha Abassi, Michigan State University

My three daughters and I arrived in Michigan from Pakistan in 2000.

Moving here was my choice, and I followed the legal process. Before the move, I had often been to the United States. I was familiar with the culture and spoke fluent English, so I thought I was prepared.

Resuming my career as a physician in the U.S. was arduous, but I finally passed all the qualifying exams and completed a psychiatry residency at Michigan State University in 2006. After finishing my studies, I stayed on as faculty.

Of course, there is nothing new or particularly unique about my family’s experience. Immigration, whether it is out of choice or forced by conflict, has always been part of the American experience. After all, the U.S. Constitution was signed by seven first-generation immigrants.

Experts will tell you that immigration makes our country stronger economically, culturally and in fields like science and medicine. Since I’m a doctor, I’m well aware that 26% of licensed U.S. physicians and surgeons are immigrants.

But it is also true that immigrants like me face stresses that harm our
psychical and mental health.

I teach cultural psychiatry to medical students and residents, specifically how to culturally appropriate care to Muslim . After more than 20 years in Michigan, I’m deeply rooted in the Muslim and immigrant community, and I’ve seen firsthand how anxious and uncertain my community is about the 2024 presidential election.

Panic attacks and depression

Republican presidential candidate Donald Trump has called immigrants “bloodthirsty criminals” and the “most violent people on Earth.” He claims that immigrants were “poisoning the blood of our country.” Research shows, and I’ve seen personally, how this kind of talk can cause anxiety and depression in immigrants both undocumented and legal.

Undocumented immigrants and their families, who live in precarious conditions and in fear of being deported, are especially vulnerable to Trump’s calls for mass deportations.

History has taught us that a politician’s hateful words can lead to violence.

In the first half of 2024, the Michigan Chapter of the Council on American-Islamic Relations documented 239 complaints of discrimination against Muslims, an 81% increase over the same period in 2023. In the , CAIR-MI Executive Director Dawud Walid attributed the uptick to “policies of elected , rhetoric of candidates running for office, along with victim blaming by some political pundits.”

Adding to the situation are the deepening crises in the Gaza Strip and Lebanon, which are making Muslims in Michigan, especially those with relatives in the Middle East, reel with palpable grief.

This rise in Islamophobia and fear of an uncertain future is taking a toll. American Muslims are twice as likely to attempt suicide compared with people from other faiths.

Anxiety in the voting booth

Like 73% of all Americans, immigrants are anxious about the election.

With the politicization of baseless claims of undocumented immigrants voting, the fact is that naturalized citizens – who have every right to take part in the election – are a formidable voting bloc, making up 1 in 10 of the nation’s eligible voters and about 5% in Michigan.

What’s more, naturalized citizens tend to vote at higher rates than native-born citizens.

Still, for many Muslims in Michigan, it is hard to know how to vote this year. I don’t trust either of the major parties.

Michigan’s Muslims are feeling devalued and disenfranchised.

A key Arab American political action committee based in Michigan refused to endorse either candidate this cycle. Although the PAC typically backs Democrats, this year it said “neither candidate represents our hopes and dreams as Arab Americans.”

In late September, a national group of three dozen Muslim American scholars and imams signed an open letter calling on Muslims not to vote for Democratic nominee Kamala Harris.

“We want to be absolutely clear,” the letter reads, “don’t stay home and skip . This year, make a statement by voting third party for the presidential ticket.”

A group called Listen to Michigan gained attention during the primaries by attracting more than 100,000 people to vote “uncommitted” as a protest against ‘s of the war in Gaza. The group has stopped short of endorsing Harris but urged voters “not to cast their ballot for anyone but her.”

Still, some of my neighbors have decided to back Green Party candidate Jill Stein.

I know my vote is my voice, and I fully intend to participate in the electoral process. But I can’t trust any of the candidates to create a safe haven for my family – a place where my daughters and I can thrive and live our American dream.The Conversation

How can Jupiter have no surface? A dive into a planet so big, it could swallow 1,000 Earths

Curious Kids is a for of all ages. If you have a question you’d like an expert to answer, send it to curiouskidsus@theconversation.com.


Why does Jupiter look like it has a surface – even though it doesn’t have one? – Sejal, age 7, Bangalore, India


The planet Jupiter has no solid ground – no surface, like the grass or dirt you tread here on Earth. There’s nothing to walk on, and no place to a spaceship.

But how can that be? If Jupiter doesn’t have a surface, what does it have? How can it hold together?

Even as a professor of physics who studies all kinds of unusual phenomena, I realize the concept of a world without a surface is difficult to fathom. Yet much about Jupiter remains a mystery, even as NASA’s robotic probe Juno begins its ninth year orbiting this strange planet.

Jupiter’s mass is two-and-a-half times that of all the other planets in the solar system combined.

First, some facts

Jupiter, the fifth planet from the Sun, is between Mars and Saturn. It’s the largest planet in the solar system, big enough for more than 1,000 Earths to fit inside, with room to spare.

While the four inner planets of the solar system – Mercury, Venus, Earth and Mars – are all made of solid, rocky material, Jupiter is a gas giant with a composition similar to the Sun; it’s a roiling, stormy, wildly turbulent ball of gas. Some places on Jupiter have winds of more than 400 mph (about 640 kilometers per hour), about three times faster than a Category 5 hurricane on Earth.

Searching for solid ground

Start from the top of Earth’s atmosphere, go down about 60 miles (roughly 100 kilometers), and the air pressure continuously increases. Ultimately you hit Earth’s surface, either land or water.

Compare that with Jupiter: Start near the top of its mostly hydrogen and helium atmosphere, and like on Earth, the pressure increases the deeper you go. But on Jupiter, the pressure is immense.

As the layers of gas above you push down more and more, it’s like being at the bottom of the ocean – but instead of water, you’re surrounded by gas. The pressure becomes so intense that the human body would implode; you would be squashed.

Go down 1,000 miles (1,600 kilometers), and the hot, dense gas begins to behave strangely. Eventually, the gas turns into a form of liquid hydrogen, creating what can be thought of as the largest ocean in the solar system, albeit an ocean without water.

Go down another 20,000 miles (about 32,000 kilometers), and the hydrogen becomes more like flowing liquid metal, a material so exotic that only recently, and with great difficulty, have scientists reproduced it in the laboratory. The atoms in this liquid metallic hydrogen are squeezed so tightly that its electrons are free to roam.

Keep in mind that these layer transitions are gradual, not abrupt; the transition from normal hydrogen gas to liquid hydrogen and then to metallic hydrogen happens slowly and smoothly. At no point is there a sharp boundary, solid material or surface.

Scary to the core

Ultimately, you’d reach the core of Jupiter. This is the central region of Jupiter’s interior, and not to be confused with a surface.

Scientists are still debating the exact nature of the core’s material. The most favored model: It’s not solid, like rock, but more like a hot, dense and possibly metallic mixture of liquid and solid.

The pressure at Jupiter’s core is so immense that it would be like 100 million Earth atmospheres pressing down on you – or two Empire State buildings on top of each square inch of your body.

But pressure wouldn’t be your only problem. A spacecraft to reach Jupiter’s core would be melted by the extreme heat – 35,000 degrees Fahrenheit (20,000 degrees Celsius). That’s three times hotter than the surface of the Sun.

Jupiter helps Earth

Jupiter is a weird and forbidding place. But if Jupiter weren’t around, it’s possible human beings might not exist.

That’s because Jupiter acts as a shield for the inner planets of the solar system, Earth. With its massive gravitational pull, Jupiter has altered the orbit of asteroids and comets for billions of years.

Without Jupiter’s intervention, some of that space debris could have crashed into Earth; if one had been a cataclysmic collision, it could have caused an extinction-level . Just look at what happened to the dinosaurs.

Maybe Jupiter gave an assist to our existence, but the planet itself is extraordinarily inhospitable to life – at least, life as we know it.

The same is not the case with a Jupiter moon, Europa, perhaps our best chance to find life elsewhere in the solar system.

NASA’s Europa Clipper, a robotic probe launching in October 2024, is to do about 50 fly-bys over that moon to study its enormous underground ocean.

Could something be living in Europa’s water? Scientists won’t know for a while. Because of Jupiter’s distance from Earth, the probe won’t arrive until April 2030.

Election anxiety doesn’t need to win − here are 3 science-backed strategies from a clinical psychologist to rein in the stress

Uncertainty about the election getting to you? Is anxiety the dominant feature of your emotional landscape, maybe with a small sprinkling of impending doom?

You are not alone. A recent survey found 69% of American adults are seriously stressed about the 2024 presidential election.

It’s difficult not to be worked up about in ‘s polarized climate. Regardless of which side of the political aisle you sit on, you may find yourself glued to your browser or TV, gobbling up every tiny tidbit of and feeling your stress levels skyrocket.

I’m a psychologist who develops and tests strategies for combating anxiety. As I constantly tell my stressed-out clients, when it to election news, there’s a fine line between being well informed and being oversaturated with information.

If you’re ready to short-circuit your stress spiral, here are three science-backed strategies for coping with anxiety in times of uncertainty.

Approach your emotions with mindfulness

Being mindful refers to the quality of awareness you bring to your experiences – specifically, nonjudgmental attention focused on what’s right now.

Mindfulness practices originated in Eastern spiritual traditions, Buddhism. Over the past several decades, mindfulness has gained popularity as a powerful tool for managing anxiety. For instance, meditation apps such as Headspace and Calm incorporate it. Even if meditation isn’t your thing, though, you can still apply nonjudgmental awareness, focused on the present, to election-related anxiety.

Be present. Anxiety can draw you into an uncomfortable spiral of “what-ifs” about the future. When you make a point to be present, you remind yourself what is actually happening right now, rather than letting hypothetical fears take over.

Although you may have serious concerns about the fate of the nation, those outcomes have not yet come to bear. As I tell my , “We’ll cross that bridge if we come to it. For now, focus on the step right in front of you.”

If you notice yourself getting carried away by of the future, you can pull yourself back to the present by bringing awareness to simple sensations – the feel of your feet on the floor, the rhythm of your breath, or the sounds around you – and remind yourself that you are safe in the current moment.

Pay nonjudgmental attention. Many people are hard on themselves for feeling strong emotions. This critical mindset might look like telling yourself that you’re overreacting, or that it’s weak to let others see that you’re upset. You might even view that uncomfortable feeling in the pit of your stomach as evidence that negative outcomes are right around the corner.

Making judgments about your emotions only serves to make you feel worse. In fact, researchers find that pushing away emotions or beating yourself up for them leads to more frequent and stronger anxiety.

Instead, try giving yourself a break. Tell yourself, “This election is high stakes, so it makes sense I’m anxious.” Then, notice if your anxiety is driven by a fear about the future, and bring yourself back to the present.

Get flexible with your thinking

Cognitive flexibility is the ability to shift away from rigid, all-or-nothing thinking about the future.

When people are anxious, they tend to focus on the worst-case scenario. For example, you might be telling yourself, “With this candidate in office, things will be terrible and I won’t be able to cope.”

In this scenario, I encourage my patients to move past that initial thought of how awful it will be and instead consider exactly how they will respond to the inauguration, the next day, week, month and so on.

Cognitive flexibility allows you to explore how you will cope, even in the face of a negative outcome, helping you feel a bit less out of control. If you’re experiencing a lot of anxiety about the election, try thinking through what you’d do if the undesirable candidate takes office – thoughts like “I’ll donate to causes that are important to me” and “I’ll attend protests.”

Choose your actions with intention

Another tool for managing your anxiety is to consider whether your behaviors are affecting how you feel.

Remember, for instance, the goal of 24-hour news networks is to increase ratings. It’s in their interest to keep you riveted to your screens by making it seem like important announcements are imminent. As a result, it may feel difficult to disconnect and take part in your usual self-care behavior.

Try telling yourself, “If something happens, someone will text me,” and go for a walk or, better yet, to bed. Keeping up with healthy habits can help reduce your vulnerability to uncontrolled anxiety.

Post-Election Day, you may continue to feel drawn to the news and motivated to show up – whether that means donating, volunteering or protesting – for a variety of causes you think will be affected by the election results. Many people describe feeling guilty if they say no or disengage, leading them to overcommit and wind up overwhelmed.

If this sounds like you, try reminding yourself that taking a break from politics to cook, engage with your family or friends, get some work done or go to the gym does not mean you don’t care. In fact, keeping up with the activities that fuel you will give you the energy to contribute to important causes more meaningfully.The Conversation
