West Nusa Tenggara Provincial Health Bureau citing Junaidi (2007) classifies osteoporosis into four types, here is the explanation:
1. Postmenopausal (primary) osteoporosis
Osteoporosis occurs due to a lack of the hormone estrogen (the main hormone in women), which helps regulate the transport of calcium in the bones. Symptoms usually occur in women between the ages of 51 and 75, but they may appear sooner or later.
The production of the hormone estrogen decreases 2-3 years before menopause and continues 3-4 years after menopause. This results in a decrease in bone mass of 1-3% in the first 5-7 years after menopause.
2. Osteoporosis of the elderly
Osteoporosis due to age-related calcium deficiency and an imbalance between rates of bone destruction (osteoclasts) and new bone formation (osteoblasts). Senilis means that this condition occurs only in old age. This disease usually occurs in people over the age of 70 and 2 times more often in women. Women often suffer from senile and postmenopausal osteoporosis.
3. Osteoporosis Seconds
Fewer than 5% of people with osteoporosis have secondary osteoporosis caused by other medical conditions or medications. This disease can be caused by a disease. Such as chronic renal insufficiency and hormonal disorders (especially thyroid, parathyroid and adrenal) and drugs (eg corticosteroids, barbiturates, antiepileptics and excess thyroid hormone). Excessive use of alcohol can exacerbate this condition.
4. Juvenile idiopathic osteoporosis
This is a type of osteoporosis whose cause is unknown. It occurs in children and young adults who have normal hormone levels and function, normal vitamin levels, and have no clear cause for the brittle bones.
