SOZO Body Composition

SOZO Bioimpedance Spectroscopy (BIS) is a non-invasive, advanced technology designed to measure fluid status and tissue composition in patients with lymphoedema, as well as monitor changes in these parameters over time.

The SOZO device provides detailed information about fluid levels, tissue composition, and the presence of swelling.

How SOZO Works​​? SOZO uses a method called bioimpedance spectroscopy (BIS), which sends small electrical currents through the body to measure impedance (resistance) at multiple frequencies. SOZO calculates the amount of fluid in the tissues and provides detailed information about tissue composition, including fat and lean mass. This allows clinicians to detect changes in lymphatic fluid and monitor the progression of conditions like lymphoedema.

Benefits of SOZO Bioimpedance Spectroscopy:

  • SOZO enables early identification of subtle changes in fluid balance, which is crucial for early intervention in conditions such as lymphoedema.

  • Unlike traditional manual methods, SOZO provides objective, reproducible data that clinicians can rely on to monitor and assess treatment effectiveness.

  • The scan is quick, non-invasive, and comfortable for patients, making it ideal for regular monitoring.

  • SOZO provides detailed information on both extracellular fluid, intracellular fluid and total body composition, helping clinicians to track fluid changes and identify areas that require attention.


  • The detailed insights from SOZO scans allow clinicians to create more tailored treatment plans and adjust them as necessary based on real-time data.

  • SOZO can help identify patients at higher risk of developing lymphoedema or other related conditions, allowing for preventative measures to be put in place.

Scan Schedule

The frequency of SOZO scans depends on the patient's condition and the advice of the healthcare provider. However, general recommendations are as follows:

  • Initial Screening: Preferably done before surgery or up to two weeks post diagnosis/surgery

    • Patients at risk of lymphoedema (e.g; after cancer treatment or surgery) may have an initial scan to establish a baseline of their fluid levels and tissue composition.

  • Routine Monitoring: If diagnosed with lymphoedema or at risk, scans can be performed regularly.

    • Typically every 3 to 6 months.

    • The frequency may be increased based on the patient’s symptoms, changes in their condition, or during active treatment phases.

  • During Treatment or Interventions: More frequent scans may be necessary when there are significant changes in a patient's treatment plan.

Important Patient Information

There is no special preparation required for a SOZO scan. However, patients should remove any jewellery, watches, socks and footwear. Pregnant women and people with pacemakers will not be scanned. The scan is performed while the patient is standing or sitting comfortably.

The scan is quick and non-invasive, typically taking 30 seconds to complete. There is no pain or discomfort during the process, and patients can resume their normal activities immediately afterward.

SOZO provides detailed data about the fluid status and tissue composition of the body. This can help detect early signs of lymphoedema, track fluid retention, and monitor the effectiveness of treatments.

Regular scans enable healthcare providers to detect any early signs of swelling or tissue changes, allowing for quicker interventions. The scans can help ensure that treatments are working effectively and allow for adjustments as needed.​

The technology used in SOZO is completely safe. The bioimpedance measurement involves sending a very small, low-voltage electrical signal through the body, which is harmless and cannot be felt by the patient

While SOZO scans can help track the condition, they are part of a broader approach to lymphoedema management. Patients should continue following their prescribed treatment plans, including compression therapy, exercise, and any other interventions recommended by their healthcare provider.
