“The Lymphatic System vs. Swelling:
Swelling (also called oedema) is more than just an aesthetic concern — it’s your body crying out for help. Whether it’s puffiness in your legs, arms, face or abdomen, the root cause often lies within your lymphatic system.
Swelling happens when interstitial fluid (the fluid between cells) accumulates in the tissues. This can occur due to:
• Poor lymphatic drainage (aka lymphatic congestion)
• Increased capillary permeability during inflammation
• Venous insufficiency
• Post-surgical or post-trauma tissue response
• Protein-rich fluid build-up in lymphedema
The lymphatic system’s job is to collect and transport this fluid — called lymph — back into the bloodstream. When it slows down or gets blocked, fluid stays behind and swelling happens.
Types of Swelling You Might See
1. Pitting oedema: Press a finger into the swollen area and a dent stays. Common in fluid retention and heart or kidney issues.
2. Non-pitting oedema: The tissue feels firm or rubbery. Often seen in lymphoedema, where lymphatic damage or overload occurs.
3. Inflammatory swelling: Accompanied by heat, redness, and tenderness due to immune response (think sprains or infections).
How the Lymphatic System Responds
The lymphatic system includes lymph vessels, lymph nodes, and lymphoid organs like the spleen and thymus. Its primary functions are:
• Maintaining fluid balance in tissues
• Transporting immune cells
• Filtering pathogens and debris
• Absorbing fats from the digestive system (via lacteals in the small intestine)
When fluid builds up, manual lymphatic drainage (MLD) can help stimulate lymphangiomotoricity (the contraction of lymph vessels), pushing fluid toward larger ducts like the thoracic duct or right lymphatic duct, which return it to the venous system.
Why Is It Important to Treat Chronic Swelling?
Leaving chronic swelling untreated can lead to:
• Tissue fibrosis (thickened, hardened tissues)
• Immune dysfunction
• Pain and mobility issues
• Secondary infections like cellulitis
What You Can Do to Support Your Lymph Flow:
• Hydrate adequately
• Practice deep diaphragmatic breathing
• Dry brushing and rebounding
• Receive regular lymphatic drainage therapy
• Reduce inflammatory foods and manage gut health
Swelling is not a surface issue — it’s your lymphatic system asking for help.
