Complete decongestive therapy coordinates several components of care.

Complete decongestive therapy for lymphedema

Complete decongestive therapy (CDT), also called complex decongestive therapy, is a coordinated approach used to manage lymphedema. Rather than relying on one technique, CDT combines hands-on treatment, compression, exercise, skin care and education.

The core components of CDT

Manual lymph drainage

Light, directional techniques may be used to support fluid movement when medically appropriate.

Compression

Short-stretch bandaging, adjustable wraps or compression garments help maintain pressure and limit fluid reaccumulation. Selection depends on limb shape, skin, circulation and daily function.

Remedial exercise and breathing

Movement under compression can activate muscle and joint pumps. Diaphragmatic breathing may complement this process.

Skin care

Protecting the skin barrier and identifying early signs of infection are essential parts of lymphedema management.

Education and self-management

Long-term results depend on a realistic home plan. Patients learn how to use compression, monitor skin, move safely and respond to changes.

Intensive and maintenance phases

CDT is often described in two phases. The intensive phase focuses on reducing swelling and preparing for long-term compression. The maintenance phase focuses on preserving results through garments, exercise, skin care and periodic follow-up.

Who may benefit?

CDT is commonly used for primary or secondary lymphedema and may be adapted for phlebolymphedema or other complex swelling after medical evaluation. It is not appropriate for every cause of edema.

What to expect at the consultation

The therapist may review medical history, tissue and skin status, functional goals, compression experience, home support and barriers to self-care. The plan should be individualized rather than sold as a fixed package.
