Varicose Veins: Causes, Signs and What Helps
Your legs feel heavy by the end of the day. You notice twisted, bulging veins under your skin that look purple or blue. Maybe your legs ache, itch, or feel restless at night. If this sounds familiar, you're not alone—varicose veins affect millions of people who are simply trying to go about their day.
The good news? There's a lot you can do to manage them and feel more like yourself again.
- Varicose veins form when blood pools in your leg veins instead of flowing smoothly back to your heart.
- They're common, often run in families, and get worse with prolonged sitting or standing.
- Lifestyle changes, movement, and compression support can help reduce symptoms and prevent them from worsening.
What is varicose veins?
Varicose veins are enlarged, twisted veins—usually in your legs—that become visible under the skin. The medical term is "varicose veins," and they happen when the one-way valves inside your veins weaken or fail. When those valves don't work properly, blood backs up instead of flowing smoothly upward toward your heart. Over time, that pooling blood makes the veins swell and twist into the rope-like appearance you can see.
Think of your calf muscles as your body's second heart. When you move and flex those muscles, they help pump blood upward against gravity. When you stay still for too long, that natural pump stops working, and blood has nowhere to go but down.
Why it happens
Everyday factors
Long hours sitting at a desk, standing on your feet all day, or spending time in heat can all slow your circulation. Crossing your legs, wearing tight clothing around your thighs, or being inactive for stretches—like during a long flight—puts extra pressure on your veins and makes pooling more likely.
Hormonal changes
Pregnancy, hormonal birth control, and hormone replacement therapy can soften the walls of your veins and weaken those protective valves. This is why many people first notice varicose veins during or after pregnancy.
Medical and hereditary causes
If your parents or grandparents had varicose veins, your risk is higher. Extra body weight, previous blood clots, and vein injury can all contribute. Age also plays a role—your veins naturally lose elasticity over time.
How to spot it
- Bulging, twisted veins that look purple, blue, or dark red under the skin
- Heavy, aching, or tired legs—especially by evening
- Swelling in your ankles or lower legs
- Itching or burning sensations along the veins
- Restless legs, especially at night
- Skin discoloration or texture changes above the ankles
- Cramping in your legs when you move
What actually helps
1. Move regularly
Walking, swimming, cycling, and stretching keep your calf muscles working and pumping blood upward. Even short movement breaks throughout your day make a real difference. Aim for at least 30 minutes of activity most days.
2. Elevate your legs
Lying down with your legs raised above heart level for 15–30 minutes helps blood flow back toward your chest naturally. Do this in the evening or whenever your legs feel heavy.
3. Stay hydrated and manage your weight
Drinking plenty of water helps keep your blood flowing smoothly, and maintaining a healthy weight reduces pressure on your veins.
4. Use compression support
Compression garments gently squeeze your legs, helping to push blood upward and reduce pooling. They can ease heaviness and swelling, especially when worn during activities or travel. Many people find them most helpful during long days on their feet or on flights.
5. Avoid prolonged stillness
Change positions frequently. If you sit for work, stand and move every hour. If you stand all day, take sitting breaks when you can.
When compression helps most
Compression garments shine during specific situations. On long flights or road trips, they support circulation while you're confined to a seat. If you're on your feet for work—retail, nursing, teaching—they can ease fatigue and reduce end-of-day swelling. During pregnancy, when hormones are loosening vein walls, compression offers extra support. Heat also makes symptoms worse, so compression during warm months or in hot climates can help keep legs feeling lighter.

Frequently asked questions
Can varicose veins go away on their own?
Varicose veins don't typically disappear without intervention, but they can be managed effectively with lifestyle changes and support strategies. The key is stopping them from getting worse and reducing your symptoms so you can stay active.
Are varicose veins dangerous?
In most cases, varicose veins are a cosmetic or comfort issue rather than a serious health threat. However, in rare cases, they can lead to complications like blood clots or skin damage. That's why it's worth talking to your doctor if symptoms worsen or new problems develop.
Do men get varicose veins?
Yes. While they're more common in women—partly due to hormonal factors—men absolutely get varicose veins too. The causes and management strategies are the same.
Can I prevent varicose veins?
If you have a family history, you can't prevent them entirely, but you can delay their onset and reduce severity by staying active, avoiding prolonged sitting or standing, keeping a healthy weight, and using compression support when you're at risk.
Varicose veins don't have to slow you down. With smart daily habits, thoughtful movement, and the right support, you can feel lighter, more energized, and ready for whatever your day brings.
