What are the dangers of low blood calcium

Hypocalcemia can cause great harm to our health. Common hypocalcemia can affect organs, leading to calcium deficiency in the blood and causing neuromuscular excitation, often manifesting as symptoms such as startle, hand and foot cramps, and convulsions.

1. "Under normal circumstances, the human body consumes 800-1000 mg of calcium per day. Children in their growth and development period need about 1200-1400 mg of calcium. Reduced calcium intake will cause dietary calcium deficiency. This situation is more common in pregnant women and infants. Calcium can be supplemented through diet or medication."

2. The most common problem caused by a lack of calcium in the blood is increased nerve and muscle excitability. When calcium is low, it will affect nerve and muscle twitching. Startles, twitching or tremors of the hands and feet, and convulsions often occur. Many patients complain that they have leg cramps when they sleep at night. This is because calcium deficiency will increase the excitability of the entire nervous system, and the organs are filled with smooth muscles, which will cause spasms.

3. Calcium deficiency will also have an impact on bones and skin. Generally, it will most affect bone development, causing osteomalacia and osteoporosis. Children will suffer from rickets. Some people with chronic diseases will cause bone pain. Some people will have dry skin, or brittle and broken nails. "Director Mou said that some may induce epileptic seizures, convulsions of the limbs, and respiratory arrest in the body. In severe cases, cardiovascular and cerebrovascular problems may occur, such as arrhythmia. Severe cases may also cause laryngeal muscle spasm, respiratory arrest, and ventricular fibrillation.

4. The examination method includes tapping the nerve (approximately in front of the ear). There is no problem for normal people, but for people with low calcium, tapping will cause facial twitching. There is also another examination called the arm restraint experiment, which is the same as measuring blood pressure. Take the blood pressure cuff, apply pressure, and wait for 2-3 minutes. People with calcium deficiency will involuntarily twitch their hands. Because low blood calcium can cause increased nerve excitability, which will manifest itself once stimulated.

5. "Many people have this misunderstanding, thinking that they will not suffer from calcium deficiency if they take calcium tablets." Director Mou gave an analogy. He said that taking calcium tablets is like transporting a pile of bricks to build a house. No matter how many bricks there are, they will not become a wall by themselves. Instead, they need the participation of vitamin D to build a house, such as getting more sun exposure. Because the prerequisite of vitamin D is cholesterol, cholesterol will turn into vitamin D when exposed to the sun, and vitamin D can promote calcium absorption. Without vitamin D, no matter how much calcium you eat, most of it will be excreted from the body with feces. Therefore, blindly supplementing calcium has little effect on the human body.
