Why do my legs feel sore after menstruation?

Menstruation can make women feel a little uncomfortable, especially some young girls who may be too fond of beauty and wear very little every day. They often catch cold and feel severe abdominal pain when their menstruation comes. Irregular menstruation will greatly affect women's daily life. Sometimes women feel soreness in the waist and knees after menstruation, which is a sign of calcium deficiency. So what causes leg pain after menstruation?

Calcium supplementation method

1. The same dose of calcium is better absorbed when taken in divided doses than in one large dose. Depending on the baby's physical condition, the amount of calcium supplementation should not exceed 200 mg each time.

2. It is best to take calcium supplements alone and avoid taking them at the same time with milk, root vegetables, zinc, iron, etc. The protein in milk combines with calcium to form milk curds, and the calcium cannot be absorbed by the body; excessive intake of oxalic acid in food will affect the absorption of calcium; the body's absorption of calcium is competitive with zinc and iron. If taken at the same time, it will not only inhibit the absorption of zinc and iron, but also interfere with the absorption of calcium itself. Therefore, calcium supplements are best taken alone. If other elements need to be supplemented, it is best to stagger the time, with an interval of more than 2 hours.

3. Calcium is better absorbed if you take it before going to bed at night. When sleeping at night, gastrointestinal motility is slower and food stays in the gastrointestinal tract longer, which is conducive to calcium absorption. Blood calcium levels are generally higher during the day and lower at night. At night, especially in the middle of the night and early morning, low blood calcium levels can stimulate the secretion of parathyroid hormone, accelerate the decomposition of bone calcium, cause decalcification, induce hypocalcemia, and in severe cases can cause convulsions in the body. Calcium supplementation before going to bed can provide a calcium source for nighttime calcium regulation and block the body's mobilization of bone calcium. Calcium is also related to the stability of the autonomic nervous system and has a sedative and hypnotic effect.

4. Calcium supplementation must include vitamin D. Vitamin D is required for calcium absorption, and calcium metabolic balance is also affected by vitamin D. You can choose to take cod liver oil (vitamin AD) or vitamin D3 preparations, or you can promote the conversion of a type of cholesterol in the skin into vitamin D through sun exposure. The Chinese Nutrition Society recommends daily supplementation of 400-800 IU of vitamin D based on the nutritional needs of infants and young children.

In short, don't miss the golden period of calcium supplementation for infants and young children. In order to achieve the best calcium supplementation effect for infants and young children, you should choose the most suitable calcium source and appropriate dosage, take it before going to bed at night, avoid taking it with milk, food, etc., and appropriately supplement vitamin D to increase calcium absorption.
