Osteoporosis(bone problem)(source:https://www.nof.org/patients/what-is-osteoporosis/)

Osteoporosis causes bones to become weak and brittle so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture.
Osteoporosis-related fractures most commonly occur in the hip, wrist or spine.
osteoporosis occurs, the holes and spaces in the honeycomb are much larger than in healthy bone. Osteoporotic bones have lost density or mass and contain abnormal tissue structure. As bones become less dense, they weaken and are more likely to break. If you’re 50 or older and have broken a bone, ask your doctor or healthcare provider about a bone density test.

most common injuries in people with osteoporosis are:
wrist fractures
hip fractures
fractures of the spinal bones (vertebrae)

Osteoporosis is a disease characterized by low bone mass and deterioration of bone tissue. This leads to increased bone fragility and risk of fracture (broken bones), particularly of the hip, spine, wrist, and shoulder. Osteoporosis is often known as the silent thief because bone loss occurs without symptoms.

Risk factors you cannot change include:
Gender. Women get osteoporosis more often than men.
Age. The older you are, the greater your risk of osteoporosis.
Body size. Small, thin women are at greater risk.
Ethnicity. White and Asian women are at highest risk. Black and Hispanic women have a lower risk.

Alendronate (Fosamax)
Risedronate (Actonel)
Ibandronate (Boniva)
Zoledronic acid (Reclast)
the most common medications prescribed for osteoporosis treatment. These include:

Possible adverse side effects associated with osteoporosis medications (bisphosphonates)
Ulcers of the esophagus
Upper GI irritation
Irregular heartbeat
Fractures of the femur
Low calcium in the blood
Skin rash
Joint, bone, and muscle pain
Jaw bone decay (osteonecrosis) (rare)
Increased parathyroid hormone (PTH)
