What are main causes of
varicose veins?
Varicose
veins occur when the veins become dysfunctional. Veins consist of one-way valves that prevent
the blood from flowing in the backward direction. When the valves begin to fail,
blood will start to collect in the veins rather than moving towards the heart.
The veins will enlarge. They often affect the legs. As these veins are the
furthest from the heart, gravity will make it harder for the blood to flow
upward.
Potential causes that lead to
varicose will include
- Menopause
- Pregnancy
- Age over 50 years
- Obesity
- Standing for prolonged periods of time
- Family history of varicose veins
What are the symptoms
associated with varicose veins?
Primary
symptoms of varicose will include veins that are misshapen, highly visible that
usually appear on your legs. You may also feel pain, heaviness, swelling, and achiness
around and over the enlarged vein. Some cases may also develop discoloration
and swelling and severe cases will lead to significant bleeding and ulcers.
How are varicose veins
diagnosed?
Your
doctor will examine your visible veins and legs while you are standing and
sitting to diagnose varicose veins. You may be asked about any symptoms or pain
that may have resulted due to the condition.
Your
doctor may also perform an ultrasound to check your blood flow. The test is
noninvasive and will use high-frequency sound waves. It will allow your doctor
to determine how your blood is flowing through your veins.
A
venogram may be done to further assess the condition of your vein. Your doctor
may inject a special dye into the vein to take an X-ray of the affected area.
The dye will appear on the X-ray giving a better view of how the blood is flowing
inside the veins.
How are varicose veins treated?
Doctors
will generally take the conservative approach when treating varicose veins. You
will be advised to make lifestyle changes before going for more aggressive
treatments. The following lifestyle changes will help in preventing varicose
veins or them becoming worse.
- Avoid standing for long periods of time
- Maintain a healthy weight
- Exercise to improve blood circulation
- Use compression stockings
