Mariana was 34 years old and decided to have lymphatic drainage to relieve swelling in her legs after a long journey. She booked the session, lay on the treatment table and, during the appointment, felt a discomfort that didn't seem normal. Only later did she discover that she had venous thrombosis that had not yet been diagnosed. Mariana's case helps us understand why lymphatic drainage, despite seeming like a simple and straightforward procedure, should not be done without a prior assessment.

Lymphatic drainage: why pre-assessment matters more than it seems

What is lymphatic drainage

Lymphatic drainage is a massage technique with light, slow and rhythmic movements, which aims to stimulate the movement of lymph through the body. Lymph is the fluid that circulates through a network parallel to blood circulation, the lymphatic system, responsible for returning fluid and proteins to blood vessels and for an important part of the immune response. When this fluid accumulates excessively in tissues, it can cause swelling, a sensation of heaviness and discomfort, and this is where drainage is usually indicated.

Why massage should not be the first step

The central point of this text is not the technique itself, but what needs to come before it. Since drainage acts directly on the lymphatic circulation and, indirectly, on the venous circulation, it may not be safe for people who have any condition that also involves these pathways. Therefore, before any session, it is important that a healthcare professional assesses the person's medical history, and not just the professional who will perform the massage.

Situations that require attention before the session

Based on the literature on the subject, some conditions require extra care or prevent the performance of lymphatic drainage:

  • Active venous thrombosis, since massage may favour the displacement of a clot
  • Active cancer, a situation in which the indication needs to be individualised by a doctor
  • Acute infections, particularly when accompanied by fever
  • Decompensated heart failure
  • Uncontrolled hypertension
  • Use of anticoagulant medications
  • Pregnancy without prior medical clearance
  • Some autoimmune diseases

This does not mean that people with these conditions will never be able to have lymphatic drainage. It means that the decision needs to be made together with a doctor, who will assess the right time and the safest way to conduct the treatment.

The care that makes the difference

Being honest about your own health history before the session is what allows the responsible professional to assess whether that is the right time for drainage. Omitting a health condition, even unintentionally, can turn a simple procedure into a risky situation.

Final considerations

Lymphatic drainage is a safe and beneficial technique for the vast majority of people, but safety is not synonymous with dispensing with assessment. Before any session, it is worthwhile to speak with a doctor about your health history, so that the indication is made correctly.
