Introduction to Osteoporosis Osteoporosis is a bone disease that causes bones to become weak and fragile. The word “osteoporosis” means “porous bones.” In this condition, bones lose density and strength, making them more likely to break. While it’s natural for bone density to decrease as we age, those with osteoporosis experience a more significant loss, leading to bones that can break even from small falls or everyday activities like bending over. Osteoporosis is often called the “silent disease” because it progresses without any obvious symptoms until a bone fracture occurs. These fractures can be very painful and may lead to other health problems, such as disability or a decrease in the quality of life. The most common fractures occur in the hip, spine, and wrist. According to the World Health Organization (WHO), osteoporosis is a major health problem affecting millions of people around the world, especially older adults and women after menopause. Our bones are always changing. They are constantly being broken down and rebuilt in a process called remodeling. In a healthy person, this process keeps the bones strong. However, in someone with osteoporosis, the rate at which bones are broken down is faster than the rate at which they are rebuilt. This imbalance causes bones to lose density and strength over time. Causes of Osteoporosis Several factors can cause osteoporosis, and many of these factors are related to each other. Here are the main causes: 1. Aging: As people get older, their bone density naturally decreases. The cells that build bones, called osteoblasts, slow down, while the cells that break down bones, called osteoclasts, continue to work at the same pace. This leads to a gradual loss of bone mass. 2. Hormonal Changes: Hormones play a significant role in maintaining bone density. For example, estrogen helps protect bones. In women, estrogen levels drop sharply after menopause, which can cause bone loss. Men also lose some testosterone as they age, which can lead to a decrease in bone density, although this happens more slowly than in women. 3. Nutritional Deficiencies: Calcium and vitamin D are crucial for strong bones. Calcium is the main mineral in bones, while vitamin D helps the body absorb calcium. If a person does not get enough of these nutrients, their bones may become weaker over time. 4. Lack of Exercise: Regular physical activity, especially weight-bearing exercises like walking, running, and lifting weights, helps keep bones strong. Without enough exercise, bones can become weak and brittle. 5. Genetics: A family history of osteoporosis or bone fractures can increase a person’s risk of developing the disease. Genetics can influence the size and strength of bones and how quickly bone mass is lost. 6. Medical Conditions and Medications: Some medical conditions, like rheumatoid arthritis or an overactive thyroid, can lead to bone loss. Long-term use of certain medications, such as corticosteroids, can also weaken bones. Symptoms of Osteoporosis Osteoporosis is called the “silent disease” because it usually doesn’t show any symptoms until a bone breaks. However, there are some signs that may indicate a person has osteoporosis: Back Pain: This can happen if a vertebra in the spine fractures or collapses. The pain may come on suddenly and be very intense, or it may develop slowly over time. Loss of Height: As the bones in the spine weaken and compress, a person might notice that they are getting shorter. Stooped Posture: Also known as a “dowager’s hump,” this is when the upper back curves forward, causing a hunched appearance. This happens because the spinal bones are too weak to support the body’s weight. Bone Fractures: Fractures in the hip, wrist, or spine are common in people with osteoporosis. These fractures can happen from minor falls or even from everyday activities like coughing or lifting something light. Prevention of Osteoporosis Preventing osteoporosis involves taking steps to maintain strong bones throughout life. Here are some key ways to prevent osteoporosis: 1.Eat a Healthy Diet: Eating foods rich in calcium and vitamin D is important for strong bones. Adults should aim to get at least 1,000 milligrams of calcium per day. Good sources of calcium include dairy products like milk, cheese, and yogurt, as well as green leafy vegetables like kale and broccoli. Vitamin D is also essential because it helps the body absorb calcium. People can get vitamin D from sunlight, fatty fish like salmon, and fortified foods. 2.Exercise Regularly: Physical activity, especially weight-bearing exercises like walking, running, and resistance training, is important for keeping bones strong. These activities help stimulate bone growth and maintain bone mass. Exercises that improve balance and coordination, such as yoga or tai chi, can also reduce the risk of falls, which is important for preventing fractures in people with osteoporosis. 3.Make Healthy Lifestyle Choices: Avoiding smoking and limiting alcohol consumption can help protect bones. Smoking is harmful to bone health because it reduces bone mass and increases the risk of fractures. Drinking too much alcohol can interfere with the body’s ability to absorb calcium and build strong bones. 4.Get Regular Bone Density Tests: Bone density tests, such as a DEXA scan (Dual-Energy X-ray Absorptiometry), can help detect osteoporosis early. These tests measure the density of bones in the spine, hip, and forearm, which are common sites for fractures. Regular testing is recommended for women over 65 and men over 70, or for younger people with risk factors for osteoporosis. 5.Prevent Falls: Reducing the risk of falls is especially important for people with osteoporosis, as falls can lead to fractures. Simple changes at home, such as removing loose rugs, installing grab bars in the bathroom, and improving lighting, can help prevent falls. Wearing supportive shoes and using a cane or walker if needed can also reduce the risk of falling. Diagnosis of Osteoporosis Osteoporosis is usually diagnosed through a bone density test, such as a DEXA scan. This test measures the density of bones in specific areas like the spine, hip, and forearm. The results of the test are given as a T-score:
