VACUMED in Seoul: intermittent vacuum therapy for heavy, tired legs

What VACUMED in Seoul is and how it works

VACUMED is an intermittent vacuum therapy (IVT) system. You lie reclined with your lower body inside a chamber sealed at the waist. The device then alternates phases of gentle negative pressure, which draws blood and fluid toward the legs and widens surface vessels, with phases of normal pressure, when that fluid flows back. The idea is to create a rhythmic pumping effect that supports blood flow in small vessels and the return of venous blood and lymph.

The concept comes from lower-body negative pressure research, originally used to study and condition the circulation of astronauts. At VEI Clinic, VACUMED in Seoul is offered after screening by Dr. HyunSung Park, a board-certified internal medicine specialist, as a supportive treatment for comfort and recovery, used alongside movement, strength work and medical care rather than instead of them.

A session is passive and quiet. You stay clothed in light shorts or leggings, and you can read, rest or listen to music while the program runs. Pressure levels and cycle timing are preset programs on the device, chosen and supervised by the clinical team rather than adjusted by guesswork.

What VACUMED may help with

If your legs swell regularly, especially on one side, or swelling leaves a dent when pressed, that needs a medical check before any device. Heart, kidney, liver, thyroid and vein problems, as well as some blood pressure medicines, can all cause swelling, and Dr. Park will look for these first.

Once those causes have been considered and ruled out, people most often try VACUMED for one of these practical reasons:

• Leg heaviness or swollen-feeling ankles after long-haul flights or long days standing
• Recovery support after hard training sessions
• A sense of lightness and comfort as part of a wider rehabilitation or circulation plan set by a clinician

Evidence and honest limits

Lower-body negative pressure and intermittent vacuum therapy have a clear physiological rationale, and they are used in some sports and rehabilitation settings. Small studies have described improvements in local circulation and recovery measures, but results vary, many trials are small, and robust evidence for specific diseases is still developing. We present VACUMED as a complement to standard care, not a treatment that fixes an underlying condition.

We do not offer VACUMED for fat loss or cellulite. Any change in leg circumference after a session reflects fluid shifts and is temporary. If body shape or weight is your main goal, the medical weight loss program or other contouring options are more appropriate, and Dr. Park will explain them.

Who should not use VACUMED, or needs specialist clearance

Because the treatment moves blood and fluid, it is not suitable for everyone. You will complete a health questionnaire and have your blood pressure and legs checked first. VACUMED is not suitable, or needs specialist clearance, if you have:

• Unstable heart disease, heart failure or uncontrolled high blood pressure
• A recent or current deep vein thrombosis or pulmonary embolism
• Severe peripheral arterial disease or complicated varicose veins
• Advanced kidney disease
• Pregnancy
• Open wounds, skin infection or recent surgery or injury in the lower body
• Implanted devices that could be affected by pressure changes

What a session is like, and safety after

Wear soft, stretchy shorts or pants and remove sharp or bulky items at the waist. After a brief check, the waist seal is fitted and an automated program runs, usually for 20 to 30 minutes, with a visit lasting about 35 to 55 minutes in total. You feel rhythmic tightness and release around the legs and a sense of warmth. Many people start with one or two sessions a week for three to four weeks, then space them out, but your plan depends on your goals.

Mild effects include a pulling feeling at the seal, warmth in the legs and occasional lightheadedness, especially if you are dehydrated, so drink water and have a light snack beforehand. Afterward, walk for a few minutes before leaving. Contact us if leg pain, swelling or dizziness persists. Call 119 for sudden one-sided leg swelling with pain, chest pain, sudden breathlessness or fainting, which can signal a blood clot or heart problem.
