I don’t know when it started, “calcium supplementation” has become a popular word. However, many people benefit from it, and some people suffer from it. Aunt Zhang is almost 70 years old this year and has been taking care of her grandson at home after retirement.

I don’t know when it started, “calcium supplementation” has become a popular word. However, many people benefit from it, and some people suffer from it. Aunt Zhang is almost 70 years old this year and has been taking care of her grandson at home after retirement. Seeing that my grandson was about to go to school with his schoolbag on his back, he finally had a rest, but his waist and legs began to hurt. My son and daughter-in-law were very filial and bought a lot of calcium tablets, sugar and nutritional supplements for her after hearing the news. Aunt Zhang took it for a long time and her legs seemed to be more flexible than before, but during a routine physical examination, she found signs of vascular sclerosis.

This time I came to the hospital for treatment and was diagnosed with coronary heart disease after coronary spiral CT.

Calcium supplementation is "closely related" to coronary heart disease!

In recent years, news about calcium deficiency and calcium supplementation has been frequently seen in the newspapers, giving birth to a wide range of products on the market. However, calcium supplementation is just right to strengthen the body, while excessive calcium supplementation will lead to new health risks.

For example, common stones in clinical practice are caused by excessive calcium supplementation. In addition, there are other hidden dangers. A study published in the New England Journal of Medicine found that excessive calcium supplementation in women can increase their probability of coronary heart disease and stroke . It is reported that the study involved 16,718 American women and 29,000 British elderly people. None of the women interviewed before the investigation began took calcium supplements. At the end of the experiment, women who supplemented with calcium tablets and vitamin D had increased their chances of coronary heart disease and stroke by 25% and 15% respectively!

Excessive calcium supplementation may lead to coronary heart disease!

If you do not pay attention to diet and exercise, the elderly, especially those who have postmenopausal , are more likely to be osteoporosis in . However, blindly excessive calcium supplementation will lead to a sudden increase in blood calcium concentration, which to a certain extent accelerates the formation of sediments in the arteries and vascular sclerosis.

Calcium ions are absorbed through the gastrointestinal tract, and then blood calcium is formed after entering the blood, and bone metabolism (calcium salt deposition is carried out) to form bones. But this does not mean that the more calcium is supplemented, the more bones it forms. Because when the calcium concentration in human cells is too high, phosphoesterase A2 will be activated, which can destroy the structure in the cell and break the DNA in the cell nucleus. When cytoplasmic is separated from cell membrane , cell wrinkle death will occur.

There are 200,000 fatal heart attacks in the United States every year, part of which is caused by the influx of calcium ions into cardiomyocytes due to calcium deposition.

Hypertension . How to supplement calcium in patients with coronary heart disease?

In my country, there is no statistics on the number of patients who died suddenly of due to excessive calcium supplementation. But as far as the cardiovascular system is concerned, such patients can be seen frequently at least in outpatient clinics.

Calcium metabolism disorder caused by excessive calcium supplementation is mainly manifested in the increase in calcium content in vascular smooth muscle, the increase in vascular tone, causing spasm , and slowing down or even stopping blood flow. Studies have confirmed that calcium antagonists (such as nifedipine , amlodipine , thiozozodone, etc.) can prevent the influx of calcium ions into the cells, thereby relieving coronary artery spasm , and ensuring the blood flow of coronary artery .

Therefore, patients with cardiovascular diseases such as hypertension and coronary heart disease should reasonably intake calcium or take the designated calcium agent under the guidance of a doctor to achieve the purpose of lowering blood pressure.

improves lifestyle first

In fact, so far, there is no particularly clear and unified statement on who needs to supplement calcium, when to start, and how long it will take. But we can always find a way to supplement calcium that suits us - dietary supplements.

Drinking milk every day, eating dairy products, shrimp skins, soybeans, etc.; secondly, choosing a healthy lifestyle is also important. Drink less or not coffee or coke; another very important thing is to quit smoking; finally, insisting on sunbathing and participating in outdoor exercise every day is also conducive to the absorption and utilization of calcium. If you still can’t be sure, you should ask the doctor and avoid blindly supplementing calcium.
