After women enter middle age, due to the sudden drop of estrogen level, their ability to absorb calcium decreases, which is prone to various calcium deficiency symptoms. So what are the symptoms of middle-aged women? Before understanding the symptoms of calcium deficiency, it is more necessary to understand the symptoms of calcium deficiency in women. Generally speaking, there are several reasons for women's calcium deficiency: First, due to the restriction of eating habits and living standards, the calcium intake of Chinese residents has been low for a long time; Secondly, the absorption of calcium decreases with age. Generally speaking, people begin to absorb calcium from their mothers, and women can absorb it until they are 22 years old and men can absorb it until they are 25 years old. The excess calcium absorbed before will be stored in our bones, which is equivalent to trying to add some steel bars to this building of our human body. This is our "capital" and our "calcium bank". Calcium absorbed from this person is basically not stored; In addition, after middle-aged women's amenorrhea, the secretion of estrogen by ovaries decreased, and the absorption capacity of calcium also decreased. These are the reasons why women lack calcium. Generally speaking, after entering middle age, there are heel pain, waist and cervical pain; Feel the teeth loose and fall off; Limb weakness, frequent cramps and numbness; Obvious hunchback and reduced height; Nails are soft and often broken; Allergy; Sleep disorders are all signs of calcium deficiency. Once the above symptoms appear, it is necessary to supplement calcium in time, such as Jody Xiuyuan Women's Tablets and Tomson Bianjian Stop Youth Capsules. In addition, it is suggested to bask in the sun more, eat more foods containing more calcium, such as shrimp, bone soup, kelp, etc., and take part in outdoor sports.
