Chronic venous insufficiency

Chronic venous insufficiency is a condition in which blood stagnates in the veins of the legs due to weakness of the venous walls and valves. It manifests as heaviness and swelling by the evening, pain, cramps, enlarged veins and changes in the skin of the lower legs. Patients with this condition are managed by phlebologists and vascular surgeons: they clarify the cause, assess the severity of the disorders and select treatment to reduce symptoms and lower the risk of complications.

For typical symptoms, book an appointment with a phlebologist or vascular surgeon as a routine case. You should seek urgent care if severe pain, redness, hot skin or sudden severe swelling appear — this may be a sign of thrombosis.

Main

  • Veins cannot cope with returning blood to the heart: the valves do not close tightly, blood flows downwards, and congestion occurs.
  • Heaviness and swelling by the evening — early signs that are easily put down to tiredness after a working day.
  • Such patients are managed by a phlebologist, and in their absence — by a vascular surgeon; if complaints persist, the visit is not postponed.
  • Ultrasound duplex scanning of the veins shows the structure of the vessels and the direction of blood flow, clarifying the picture.
  • Sharp pain in the leg, redness and hot skin — a reason to seek medical help urgently, not routinely.

What is chronic venous insufficiency

Chronic venous insufficiency is a condition in which the veins of the legs cannot cope with returning blood to the heart. Blood stagnates in the lower limbs, causing heaviness, swelling and other unpleasant sensations that worsen towards the evening.

What happens in the body

Chronic venous insufficiency begins with a disruption in the function of the venous valves, which normally allow blood to pass only upwards. When the valve leaflets do not close tightly, blood under the force of gravity rushes back down. Because of this, stagnation occurs in the lower limbs, and the walls of the veins experience increased pressure. Gradually the veins lose tone and stretch, becoming visible under the skin. The liquid part of the blood seeps through the vessel wall into the surrounding tissues, which by the evening manifests as swelling of the feet and lower legs. A person notices heaviness, a feeling of fullness and fatigue in the legs, worsening after prolonged standing or sitting. If these signs are ignored, the stagnation gradually increases over time, so it is important not to postpone a visit to the doctor if discomfort persists.

What causes it to develop

  • Hereditary predisposition: weakness of the vessel wall and valve apparatus is often passed down through the family line, increasing the likelihood of early appearance of signs.
  • Prolonged standing or sitting: a motionless position makes it harder for blood to flow out of the legs, because the calf muscles stop working as a pump.
  • Sedentary lifestyle: a lack of regular walking reduces the natural training of the venous walls and weakens their ability to push blood upwards.
  • Pregnancy: the growing uterus presses on the pelvic veins, and hormonal changes additionally relax the vessel wall, increasing stagnation.
  • Excess weight: extra kilograms increase pressure on the veins of the legs and make it harder for blood to rise to the heart, accelerating the appearance of swelling.
  • Older age: over the years the valves and walls of the veins wear out, so the risk increases even without obvious provoking circumstances.

Who experiences this more often

Chronic venous insufficiency is more common in people whose work or lifestyle involves prolonged standing or sitting. Shop assistants, hairdressers, office employees and drivers spend most of the day in a motionless position, so their veins experience constant strain. Women experience this condition more often than men, especially during pregnancy, when additional pressure acts on the pelvic veins. Excess weight and older age place a person in a higher-risk group, since these circumstances weaken the vessel wall. Heredity also plays a noticeable role: if close relatives had similar complaints, the likelihood of signs appearing increases. Even when feeling well, it is worth taking these circumstances into account and not ignoring regular heaviness in the legs. A sensible step is to discuss any persistent changes with a doctor, rather than dismissing them as ordinary fatigue.

What symptoms can occur?

Chronic venous insufficiency develops gradually, and the early signs are easily mistaken for ordinary tiredness. Let us look at what is noticed at the beginning, which symptoms are most common and when urgent help is needed.

How it is noticed at the very beginning

At the beginning, chronic venous insufficiency makes itself known through heaviness and tiredness in the legs towards the evening. A person puts this down to a long working day, the journey or hot weather. By the end of the day the calves seem to swell, the shoes begin to pinch, and one wants to sit down and raise the legs higher. Many notice that after resting with the legs raised it becomes noticeably easier. Gradually, swelling is added to the heaviness, and it usually subsides by the morning. Then visible changes in the veins and darkening of the skin on the calf appear. If such signs recur day after day, it is worth seeing a phlebologist without waiting for the swelling to worsen.

Signs that occur most often

  • Heaviness and tiredness in the legs: they arise towards the end of the day and worsen after prolonged standing or sitting, and usually pass by the morning.
  • Swelling towards the evening: the calves and feet swell, the shoes become tight, and after a night's rest the swelling subsides.
  • Pain or a bursting sensation in the calves: felt as pressure from within, they make walking difficult and noticeably worsen towards the evening.
  • Night cramps: sudden painful contractions of the calf muscles wake one at night and disturb sleep.
  • Visible enlarged veins: twisted dark vessels show through under the skin and become more noticeable over time.
  • Change in skin colour on the calf: the skin darkens, thickens and may itch, which indicates a long-standing impairment of outflow.

Examinations and tests

Examination for chronic venous insufficiency begins with a conversation and a physical examination, and instrumental methods only refine the picture. Below is what exactly is used, what each investigation shows and what information is worth bringing to the appointment.

How the examination begins

Chronic venous insufficiency is recognised primarily through examination and questioning about complaints, and this is not a formality but the basis for further decisions. The doctor examines the legs, assesses skin colour, swelling, dilated veins and traces of past inflammation. Palpation helps to feel the density of the tissues, local temperature and painful areas along the veins. Separately, it is clarified when the discomfort appeared, how it changes during the day and whether it is related to exertion or rest. Such details make it possible to distinguish venous manifestations from swelling of another origin and to choose the right direction of investigation. If the examination leaves questions, the doctor may prescribe instrumental investigations to assess the condition of the veins and blood flow. Before the appointment, it is worth recalling the history of your symptoms in advance, because an accurate account speeds up the choice of method and saves you from unnecessary procedures.

What is worth preparing for the appointment

  • Discharge summaries: bring all previous conclusions and examination reports so that the doctor can see the history of observations and does not prescribe again what has already been done.
  • Previous images: bring printouts and descriptions of ultrasound investigations of the veins, if they were done before, for comparison of the picture.
  • List of complaints: write down when heaviness, swelling or pain appear and what makes them worse, so that you do not forget anything at the appointment.
  • Observations of the legs: note whether the swelling changes by the evening, after long walking or in hot weather, because these details help in the assessment.
  • Questions for the doctor: formulate in advance what exactly is unclear about the condition of the veins and which investigations lie ahead, so that the appointment is meaningful.

Which doctor should I see?

If chronic venous insufficiency is suspected, it is important to understand which doctor to see and how care is organised. Below we explain who manages such patients, what treatment consists of, and what depends on the person themselves.

Which specialist manages this condition

Chronic venous insufficiency is managed by a phlebologist, or, in their absence, by a vascular surgeon. A phlebologist deals specifically with veins and knows well how their function changes in this condition. A vascular surgeon manages a broader range of vascular problems and also sees such patients. At the first appointment, the doctor asks about complaints and examines the legs, assessing swelling and skin changes. They palpate the veins, observe how they fill, and check whether there are any indurations along them. If a specialist is not available nearby, start with a vascular surgeon or a physician who will refer you further. Do not postpone the visit if heaviness and swelling in the legs recur day after day.

What treatment consists of

  • Compression therapy: special hosiery creates external pressure on the veins and helps blood move upwards, reducing heaviness and swelling.
  • Selection of therapy by the doctor: the specialist assesses the stage and symptoms and decides which methods are suitable for you specifically, as there is no universal approach here.
  • Physiotherapy: certain procedures complement the main treatment and help reduce discomfort in the legs when used regularly.
  • Surgery when indicated: surgical intervention is considered when conservative methods do not give the desired effect and the condition requires more decisive measures.

What depends on the patient themselves

A significant part of the result in chronic venous insufficiency rests on regular follow-up with the doctor. The condition changes gradually, and an unfavourable turn can only be noticed at repeat examinations. If visits are missed, the doctor will not see how the veins behave over time and will not be able to adjust care in time. Compression hosiery works only when worn as recommended, not from time to time. Physiotherapy is also undergone in the prescribed order, otherwise the effect is lost. The patient themselves notices when swelling increases or heaviness appears, and reports this at the appointment. Keep simple notes about your sensations and come for examinations at the appointed times.

What helps prevent an exacerbation?

Prevention in chronic venous insufficiency helps slow the progression of the disease and reduce symptoms. Below is what depends on the person themselves and how regular monitoring reduces the risk of exacerbation.

What is changed in habits

Regular physical activity supports the work of the venous system and reduces blood stasis in the legs. Walking, swimming and moderate gymnastics engage the calf muscles, which push blood upwards through the vessels. Prolonged standing or sitting without breaks, on the contrary, slows blood flow and increases heaviness in the legs. It is useful to change position every half hour: walk about, rise onto your toes, shift from foot to foot. Maintaining a normal weight reduces the load on the veins and decreases pressure in the vessels of the lower limbs. Compression garments, selected on the doctor's recommendation, help the veins cope with the reverse flow of blood. If your work involves long sitting, it is worth keeping your legs slightly raised and not crossing them under the chair. Such daily decisions do not replace the prescribed treatment, but noticeably ease the course of the condition.

What should be kept under control

  • Body weight: extra kilograms increase pressure in the veins of the legs, so it is worth tracking it regularly and keeping it within a comfortable range.
  • Duration of standing and sitting: if the day is spent on your feet or in a chair, it is important to plan short breaks for a warm-up and a change of posture.
  • Sensations in the legs: heaviness, swelling by the evening and fatigue show how the condition responds to load and rest during the day.
  • Wearing compression garments: these are selected by the doctor, and how regularly you wear them determines the support of the veins during the day.
  • Level of activity per week: it is worth honestly assessing how many days you moved, because it is movement that supports venous outflow.
  • Routine check-ups: even with good health, a visit to the doctor helps to notice changes in time and adjust recommendations.

How often to see a doctor

A regular examination by a doctor is needed even when the legs do not bother you and the condition seems stable. Chronic venous insufficiency can develop gradually, and external signs do not always coincide with internal changes in the vessels. The doctor assesses the complaints, examines the legs and, if necessary, prescribes an examination to see the dynamics. At the appointment, it is worth telling how often heaviness and swelling appear, what changes after rest and how you tolerate the load. If your work involves long standing or sitting, this is also important to report: the doctor will advise how to structure the day with breaks. The frequency of visits is determined by the specialist, guided by your symptoms and the results of the examination. It is not worth skipping routine appointments: timely adjustment of recommendations helps keep the condition under control.

What is worth remembering

Chronic venous insufficiency is a long-term condition, and decisions about it are made together with a doctor, not on advice from the internet. Below is the main thing worth taking away from this text.

Key takeaways

Chronic venous insufficiency develops gradually, so early changes are easily put down to tiredness after a long day. Heaviness and swelling by the evening, a noticeable network of veins, cramps in the calves are a reason to see a doctor, not to wait until it gets worse. Chronic venous insufficiency does not go away on its own: without attention to it, the changes accumulate and affect more and more veins. Many people put off the visit because during the day they feel fine, and by the evening they blame it all on the workload. Meanwhile, it is precisely at the early stage that it is easiest to slow the progression and preserve the usual rhythm of life. Chronic venous insufficiency requires not a one-off solution, but constant attention to yourself. The mainstay here is regular follow-up with a specialist and sensible everyday habits, not the hope for a miracle.

Questions and answers

Answered by the article’s medical editor.

Does chronic venous insufficiency occur in children?

Usually not, this condition is rare in children. A predisposition to weak venous walls can be inherited, but the first complaints appear in adulthood. If a child has visible enlarged veins or swelling of the legs, this is a reason to show them to a doctor in order to rule out other causes.

How does the course differ in the elderly?

In the elderly, symptoms are usually more pronounced. Over the years, the valves and walls of the veins wear out, so swelling, heaviness and skin changes on the lower legs increase faster. It is especially important for elderly people not to attribute these signs to age and to see a specialist regularly.

Can one play sports with this condition?

Yes, moderate activity is beneficial. Walking, swimming and gymnastics engage the calf muscles, which help blood move upwards. It is worth avoiding sports with sharp jumps and heavy loads on the legs, and it is better to ask a doctor about a suitable regimen.

How does pregnancy affect the course of the disease?

During pregnancy, symptoms often worsen. The growing uterus presses on the pelvic veins, and hormonal changes relax the vascular wall, so swelling and heaviness in the legs become more noticeable. After childbirth the condition often improves, but medical supervision during this period is important.

Is it inherited?

Yes, heredity plays a noticeable role. Weakness of the vascular wall and the valve apparatus is often passed down through the family line, so the risk of early onset of signs is higher. If close relatives have had similar complaints, this should be mentioned to the doctor at the appointment.

Can the condition go away on its own without treatment?

No, it does not disappear on its own. Without attention, the changes in the veins accumulate gradually and affect more and more vessels. Seeking medical help early helps slow the progression and preserve the usual rhythm of life for longer.

What complications are possible if one does not seek medical supervision?

Over time, the congestion increases and can lead to persistent changes in the skin of the lower legs, hardening of the tissues and long-healing lesions. Sharp pain, redness and sudden severe swelling of the leg are especially dangerous: in such cases, urgent medical help is needed, not a routine visit.

Which doctor should one go to if there is no phlebologist nearby?

To a vascular surgeon or a physician. A vascular surgeon deals with a wide range of vascular problems and sees such patients, while a physician will examine and refer to the right specialist. One can start with either of them if there is no specialised doctor nearby.

Is medical supervision needed if the legs no longer bother one?

Yes, routine check-ups are needed even when one feels well. The condition develops gradually, and external signs do not always match the changes in the vessels. The doctor will assess the dynamics and, if necessary, adjust the recommendations, so appointments should not be skipped.

Does working while standing or in an office affect the course of the disease?

Yes, it has a noticeable effect. Prolonged standing or sitting without breaks slows blood flow and increases heaviness in the legs, because the calf muscles stop working as a pump. It is useful to change position every half hour: walk, rise on tiptoes, shift from one foot to the other.
