Osteoporosis is a disease characterized by low bone mass and deterioration of bone tissue. This leads to an increased risk of fractures, especially in the hip, spine, and wrist. Osteoporosis affects both men and women, but women are four times more likely to develop the disease than men due to changes in hormone levels during menopause. Some key facts about osteoporosis:

  • It often develops slowly over several years without symptoms until a fracture occurs
  • It is called a "silent disease" because bone loss occurs without symptoms
  • Estrogen deficiency is a major risk factor in women
  • Age, family history, small body frame, and certain medications also increase osteoporosis risk

What Happens in Osteoporosis

In healthy bones, new bone is continuously being formed while old bone is being absorbed by cells called osteoclasts. During childhood and teenage years, new bone is formed faster than old bone is absorbed. Bone mass peaks around age 30.

In osteoporosis, this bone remodeling process is disrupted. Osteoclasts absorb bone faster than osteoblasts can form new bone. As a result, bones gradually become less dense and more porous and fragile over time. This can lead to fractures with only minor stresses like bending over or coughing. Vertebrae in the spine and the hip bones are most commonly affected.

Symptoms and Complications

There typically are no warning signs until a fracture occurs. Fractures most often occur in the hip, spine, and wrist, and can have serious consequences:

  • Spinal fractures can cause back pain, loss of height, and stooped posture
  • Hip fractures often require hospitalization and major surgery

Besides fractures, osteoporosis can also contribute to chronic pain due to compressed nerves from collapsed vertebrae.

Prevention and Treatment

The best prevention against bone loss is getting enough calcium and vitamin D. Weight-bearing exercise also helps stimulate new bone formation. For those at high risk, medications may be used to slow bone loss and reduce fracture chances. These may include bisphosphonates like alendronate (Fosamax), hormone therapy, or other drugs.

While there is no cure, the good news is that osteoporosis can often be prevented and treated! Maintaining a balanced diet with calcium and vitamin D, engaging in regular physical activity, and understanding your personal risk can go a long way toward maintaining healthy and strong bones throughout life.
