Let’s see what causes varicose. The source of this condition is the improper function of the veins located in the human limbs. Most often, the legs and all their parts are meant under the limbs. Blood basically transfers to the human heart. It is possible because of the valves in the veins. Because the veins in legs lie further onward the heart and the gravitation of the earth affects them stronger, it’s hard for the blood to flow to one’s heart. The above-mentioned factors explain how varicose develops.

The valves in the patient’s veins fail and don’t close completely. It means the blood gathers in one place instead of spreading further in the organism. The veins stop accomplishing their main function: moving blood to the heart. It causes one’s veins to enlarge. Their walls become weakened and wear thin. How can the varicose veins be diagnosed? The veins afflicted with varicose are clearly seen under the skin, so the easiest method to diagnose varicose is the visual diagnostics. When a doctor wants to discover the severity of the varicose, the doctor can prescribe the physical examination and the clinical diagnostics.

To see what happens in the suffering organism (e.g. the way bloodstream circulates and different parts receive amounts of blood) and what alterations take place in the veins structure, the doctor can prescribe the ultrasound examination, which is called Doppler. This examination can also show if there are any clot in the veins of the examinee. The other and the more advanced examination is the duplex ultrasound scan. Performing it, the doctor will see the picture in color and for more details.
