Disturbed hormonal secretion, baby's weight, weakened veins ... pregnancy promotes circulation problems and varicose veins may appear on your legs, mainly in the third trimester.
Varicose veins, what is it?
- Veins that no longer work properly. The veins bring oxygen-depleted blood back to the heart, up to 7,000 liters a day, flowing in a venous system of about 14 kilometers. In each vein there are, 2 to 3 centimeters apart, small venous valves: double doors which open only in one direction. They ensure that the blood flows only upwards.
How does a vein become varicose?
- If the tissues of the vein wall softenveins do not have enough support from the outside. They dilate, then the valves do not close properly: the blood does not rise anymore, but it refluxes and the vein continues to dilate. In the long run, it becomes tortuous, sinuous and swollen. It's a varix.
What do we recognize varicose veins?
- Most of the time, they are visible. But sometimes they are located inside the leg. Often, they appear first at the ankle. If you do not fit in your shoes, it may be a sign ... Other features: night cramps or tired legssheavy or swollen, warm on palpation, giving you the sensation of tingling or tingling.
Why does pregnancy cause varicose veins?
- With your baby's weight, the pressure in the veins increasesthe growth of the uterus prevents irrigation of the veins in the groin, and in general, more blood must be pumped into the body.
- Finally, if progesterone facilitates the relaxation of tissues for delivery, it dilates the veins, hence the appearance of varicose veins. Know that heredity also has a role to play.
