Every day, the calcium requirement for the human body is 800mg for adults. For patients diagnosed with osteoporosis, the daily calcium supplementation required is between 1000mg and 1200mg. There are many calcium formulations on the market, such as calcium carbonate, liquid calcium, and calcium citrate. Each manufacturer produces different types of calcium, and the content of trace elements of calcium varies, so it cannot be generalized. Therefore, patients with osteoporosis who buy different types of calcium should follow the instructions of different medications when taking them. In addition to calcium supplementation, patients with osteoporosis must also remember to supplement with vitamin D daily.

What to do about osteoporosis pain?

After osteoporosis leads to pain, we first need to clarify which part of the body the pain is located, or what causes the pain. If the pain is solely due to osteoporosis, such as decreased bone density in the limbs causing soreness and weakness, it is appropriate to supplement with calcium and vitamin D while also enhancing exercise to alleviate the pain. If the pain is due to fractures caused by osteoporosis, such as vertebral compression fractures or rib fractures, the fractures should first be repositioned, immobilized, and stabilized. Additionally, medications that treat osteoporosis should be used, such as those that inhibit bone resorption and promote bone formation.

What are the symptoms of osteoporosis?

What are the symptoms of osteoporosis? Osteoporosis is a metabolic bone disease characterized by decreased bone mass, destruction of bone tissue microstructure, increased bone fragility, and susceptibility to fractures. Osteoporosis can be divided into primary and secondary types. Pain is the most common symptom of primary osteoporosis, commonly seen as back pain, with the pain spreading along the spine to both sides. The pain decreases when lying on the back or sitting, and increases when standing upright, bending backwards, or after long periods of sitting or standing. Additionally, osteoporosis can lead to a decrease in height, hunchback, and fractures are the most common and serious complications of osteoporosis.

Causes of osteoporosis

Osteoporosis is primarily characterized by a reduction in bone mass, deterioration of bone tissue microstructure, and increased bone fragility, leading to an increased risk of fractures. It is a metabolic bone disease. Some cases are primary, also referred to as postmenopausal osteoporosis, which generally lacks specific causes and is mainly linked to estrogen deficiency. There is also a category known as secondary osteoporosis, which has a variety of causes, primarily secondary to metabolic endocrine disorders such as hyperparathyroidism, Cushing's syndrome, diabetes, and growth hormone deficiency. Additionally, some hematologic disorders, such as leukemia and lymphoma, can lead to osteoporosis. There are also some less common or rare diseases like osteogenesis imperfecta and scurvy that can cause osteoporosis. Furthermore, long-term use of certain medications, such as corticosteroids and anticonvulsants, can lead to osteoporosis. Kidney diseases, such as chronic renal failure and renal tubular acidosis, can also cause osteoporosis.

Osteoporosis lacks what element?

Osteoporosis refers to a systemic skeletal disease characterized by decreased bone density and strength, resulting in increased bone fragility and potential fractures. There are primarily two types of osteoporosis: primary and secondary. Primary osteoporosis commonly occurs in postmenopausal women and as a result of aging and degenerative changes; secondary osteoporosis sometimes refers to the condition developing after fractures due to prolonged immobilization. Osteoporosis mainly arises from a deficiency in the trace elements calcium and phosphorus, which are crucial components of bone. A lack of these substances can alter bone structure and lead to osteoporosis.

What is lacking in osteoporosis?

Osteoporosis refers to a systemic bone disease characterized by an imbalance in the mineral content within bone structures, such as calcium and phosphorus, as well as the bone matrix, such as collagen, leading to decreased bone hardness and damage to the bone's microstructure. This structural change results in increased brittleness, thereby raising the risk of fractures. It is primarily caused by a disruption in the normal proportional relationship between inorganic salts and the bone matrix, generally due to the loss of inorganic salts like calcium and phosphorus.
