Osteoporosis

Why after almost all parties, vying to overcome vitamin A deficiency situation in the world, suddenly appeared warning excess of vitamin A? The reason is the high cases of disease or osteoporosis, bone fragility among citizens of developed countries. In the United States alone, the national health institute reported, more than 10 million citizens suffer from the symptoms of bone fragility. Approximately 80 percent of sufferers are women. Approximately 18 million other Americans, suffered from symptoms of decreased bone density, which shows the early development of osteoporosis.
In the study it was found, a variety of causes and not just due to excess vitamin A alone. There is a genetic disease, lack of calcium consumption, smoking habits or effect too excessive alcohol consumption. However, in recent years, researchers focused on the link between excess vitamin A with the risk of bone fragility.

Trigger, is the consumption of synthetic vitamin A in large numbers in developed countries due to the vigorous campaign about the dangers the lack of vitamin A.

In a study in Sweden, where the case of bone fragility due to excess vitamin A is very prominent, seen significant relationships regarding it.

The study of 72,000 women who are menopausal, who consumed vitamin D in supplement form is equivalent to 3000 micrograms per day, or about three times its needs, represent risk of bone fragility that is also more than tripled. While research on the 2000 men in Sweden, the retinol levels in their blood higher than normal, seen also increased risk of bone fragility. Sweden became an interesting example, because the population is taking vitamin A in high levels, coupled with a lack of vitamin D biosintesa, due to lack of sunlight.

forward. While in developing countries, who worry even vitamin A deficiency in children and pregnant or lactating mothers. Menu citizens in developed countries assessed by the study, sufficient for vitamin A daily.

Moreover, if in their food menu, including beef liver or chicken liver, which contain high levels of retinol. In essence, the researchers warned, if the menu daily food already contains high levels of vitamin A, no longer need to take supplements of vitamin A.

Especially also warned the elderly who have bone fragility risk is higher. In elderly people, have decreased liver function and less effective in processing the excess retinol, mean levels of vitamin A in their bodies high enough, and usually do not need supplements again. However, if it takes supplements of vitamin A, it is recommended to consume in the form of beta-carotene. Thus vitamin A requirements can be fulfilled optimally without increasing risks. Also recommended, so that risk groups such as women who had entered menopause or elderly, consult with a doctor to determine safe levels that can be consumed.

    Could you ask your doctor for pain medication? He might even be able to do this over the phone if he is familiar with you. If you don’t have a doctor at this time, you could try to brace the area that hurts and apply heat or cold. I don’t how long you have been suffering with this pain, but perhaps some new fractures have developed to cause this. It is unclear to me if you are taking any .
