Dosing and administration

Magnesium B6 for uterus during pregnancy

Hypertension of the uterus during pregnancy is one of the indications for the appointment of magnesium B6. Most often this symptom occurs in the first trimester of bearing the fetus. Hypertonus is characterized by the fact that the woman's uterus is too tense, which greatly increases the risk of miscarriage. Magnesium helps to reduce the tone of the uterus, thereby protecting the woman from the undesirable consequences of his deficiency.

Irritability, severe fatigue, nervousness, stress and depression severely affect the muscle tone during pregnancy. Spasms can occur in all muscles, including the uterus. To improve the condition of a pregnant woman, gynecologists often recommend taking Magnesium B6.


Magnesium B6 for edema during pregnancy

Swelling quite often occurs during pregnancy, in particular, in the second half. In this case, the woman has the following unpleasant symptoms:

  1. Numbness of the hands.
  2. Heaviness in the legs.
  3. Rings and shoes begin to reap and rub strongly.
  4. If you press your fingers on the area of the edema, then at this point a "pit" is formed, which lasts a long time.
  5. The skin becomes pale and too smooth.

The causes of the appearance of edema during pregnancy are many. Most often, puffiness on the legs is caused by the fast growing uterus, which begins to press on the neighboring organs. Such edema is considered physiological and does not pose any danger to a woman or her unborn child.

But in some cases, edema can occur for more serious reasons. For example, in this category of etiological factors can be attributed to the improper functioning of the kidneys, liver or heart. An important component of therapy for such edema is the strengthening of the vascular wall of the arteries and veins. For this purpose, doctors recommend the use of magnesium B6.
