The Role of Osteoporosis in Bone Deterioration and Its Prevention

Due to aging and other factors, bones become weak and deteriorate, a condition known as osteoporosis. This disease primarily affects the elderly, with women being at higher risk than men. 

Osteoporosis is a silent yet highly dangerous bone disease that gradually weakens, makes fragile, and deteriorates bones. In simple terms, it is called bone loss. It is a condition where the density or quality of the bones (Bone Mineral Density) gradually decreases. As a result, the structure of the bones becomes hollow from the inside, making them prone to fracture from even a small impact or pressure. According to the World Health Organization (WHO), one in every three women over the age of 50 and one in every five men worldwide are affected by osteoporosis. In developing countries like Bangladesh, the prevalence of this disease is even higher due to malnutrition and a lack of health awareness.

Every year on October 20, the International Osteoporosis Foundation observes World Osteoporosis Day. The goal of this day is to raise awareness about bone health worldwide. This year’s theme for the day is ‘It’s Unacceptable!’, meaning there should be no compromise on the treatment and awareness of osteoporosis.

What Causes Osteoporosis or Bone Loss?

The primary cause of osteoporosis is a deficiency of calcium, phosphorus, and vitamin D in the body. As one ages, the hormonal balance in the body changes, especially in women after menopause when the level of estrogen decreases. Estrogen helps maintain bone density, so its deficiency causes bones to deteriorate quickly. In men, a decrease in testosterone levels with age can lead to similar issues. Additionally, lack of sunlight, poor nutrition, lack of physical activity, smoking, and excessive alcohol consumption significantly increase the risk of osteoporosis.

Osteoporosis is often called a "silent thief" because it gradually deteriorates the bones without the individual even noticing it. In the early stages, there are no visible symptoms, but later on, symptoms like a curved spine, back pain, reduced height, pain while standing or walking, and fractures from minor injuries can occur. Often, people do not realize the severity of their bone loss until the first bone fracture happens.

Who Is at Risk of Osteoporosis?

The following groups are at increased risk of osteoporosis:

·         People over the age of 50 (especially women).

·         Women after menopause (post-menopausal).

·         Smokers and excessive alcohol consumers.

·         People who consume inadequate calcium and vitamin D.

·         Those with a lack of physical activity or exercise.

·         Long-term use of steroid or thyroid hormone medications.

·         People with chronic kidney or liver diseases, hormonal disorders, or certain autoimmune diseases may also accelerate bone deterioration.

Bone Loss Measurement

The most important test to measure the degree of bone loss is the Bone Mineral Density (BMD) test, also known as the DEXA scan. This test measures the bone density in specific areas of the body, such as the hips, spine, or wrist. Based on the results, a doctor can determine whether the patient's bone density is normal, has some decrease (osteopenia), or if the patient has osteoporosis. Early detection allows for lifestyle changes and certain treatments that can control bone loss.

Prevention of Osteoporosis is the Best Approach

The key to preventing and controlling osteoporosis is proper nutrition, regular exercise, and a healthy lifestyle. It is crucial to consume enough calcium and vitamin D to keep bones strong. Foods rich in calcium include milk, yogurt, cheese, small fish (especially dried fish with bones), eggs, nuts, tofu, sesame seeds, spinach, kale, broccoli, and bananas. Vitamin D is produced in the body when exposed to sunlight, so it is important to stay in the sun for at least 15-20 minutes daily. During winter or when there is a lack of sunlight, vitamin D supplements can be taken under the guidance of a doctor.

Regular Exercise: Being physically active is one of the most effective methods to prevent osteoporosis. Regular exercise helps increase bone density and strengthens the bone structure. Weight-bearing exercises (such as walking, running, climbing stairs, and squats) and resistance exercises (such as light weightlifting or stretching) are particularly beneficial for bones. Additionally, activities like yoga or balance training help maintain balance and reduce the risk of falling, which could lead to fractures.

Avoiding Smoking and Alcohol: Smoking and excessive alcohol consumption are extremely harmful to bone health. These habits reduce the body's ability to absorb calcium and disrupt hormonal balance. Therefore, it is important to completely avoid smoking and alcohol to prevent osteoporosis. Excessive caffeine consumption (such as coffee or soft drinks) also reduces calcium absorption, so it should be limited.

Medical Treatment for Osteoporosis: While osteoporosis cannot be completely cured, its progression can be slowed with treatment. Doctors usually prescribe specific medications that help reduce bone loss and aid in the formation of new bones. For example, bisphosphonates prevent bone loss, selective estrogen receptor modulators (SERMs) help maintain hormonal balance, and calcitonin or teriparatide injections assist in bone remodeling. For women, hormone replacement therapy (HRT) after menopause can sometimes be effective, but it should only be used under a doctor's supervision.

Bone Density Test (BMD): Individuals over 50 or those in high-risk groups should undergo a Bone Mineral Density (BMD) test at least once a year.

Raising public awareness about osteoporosis prevention is also very important. Many people believe that bone loss is only a problem for the elderly, but in reality, bone density begins to decrease after the age of 30. Therefore, from a young age, it is important to maintain a balanced diet, exercise regularly, and adopt healthy habits. People who sit for long periods at work should try to take short walks or engage in physical activity.

Mental stress can also be a hidden cause of bone loss. When stress hormones like cortisol are excessively released in the body, it can reduce bone density. Therefore, it is essential to manage stress through meditation, adequate sleep, and a positive outlook on life.

Conclusion

In conclusion, osteoporosis is a condition that gradually deteriorates the bones from within, but with some awareness and changes in lifestyle, it is entirely possible to prevent it. Regular health check-ups, a nutritious diet, exposure to sunlight, regular exercise, and avoiding harmful habits can significantly reduce the risk of bone loss. As the saying goes, “Prevention is better than cure,” this applies fully to osteoporosis as well. Take care of your bones, because strong bones are the foundation of a healthy and active life.
