What are the reasons for severe calcium loss

Severe calcium loss may be related to factors such as aging, imbalanced diet, lack of exercise, insufficient vitamin D, endocrine disorders, etc. Calcium is an important mineral for maintaining bone health, and long-term calcium loss can easily lead to problems such as osteoporosis.

1. As age increases, the body's ability to absorb calcium gradually decreases, especially in postmenopausal women where estrogen levels decrease, which accelerates calcium loss. Bone mass gradually decreases after reaching its peak around the age of 30, and middle-aged and elderly people need to pay special attention to calcium supplementation and bone density monitoring.

2. Unbalanced diet

Long term high salt, high protein, or phosphate containing beverages can promote urinary calcium excretion. When the intake of calcium rich foods such as dairy products and soy products is insufficient, or when lactose intolerance exists, the daily supply of calcium is difficult to meet the demand, leading to the mobilization and release of calcium in the bones.

3. Lack of exercise

Mechanical load stimulation can promote bone formation. Long term sitting or bed rest can lead to a lack of stress stimulation in the bones and increased osteoclast activity. Regular weight-bearing exercises such as walking and skipping rope can help slow down the rate of calcium loss.

4. Vitamin D deficiency

Vitamin D can promote intestinal calcium absorption, but insufficient sunlight or liver and kidney diseases can affect its activation. When lacking, even if calcium intake is sufficient, the absorption rate will still decrease, resulting in a negative balance of calcium metabolism. Suggest supplementing with sun exposure or fortified foods.

5. Endocrine disorders

Hyperparathyroidism, thyroid dysfunction, and other diseases can lead to disturbances in blood calcium regulation. Long term use of certain drugs such as glucocorticoids can also interfere with calcium and phosphorus metabolism, and such situations require targeted treatment for the underlying disease. Preventing calcium loss requires comprehensive intervention, with a daily intake of 300-500 milliliters of milk or equivalent dairy products, paired with dark green vegetables, tofu, and other foods. Engage in 3-5 sessions of sun exposure and resistance exercises per week, avoiding excessive alcohol and coffee consumption. People over 40 years old are recommended to undergo regular bone density testing. If there are obvious symptoms, medical attention should be sought to investigate secondary causes. If necessary, calcium supplements or anti osteoporosis drugs should be used under the guidance of a doctor.
