Understanding Swelling

Why Swelling Happens & What Your Body Is Telling You

Most people experience swelling at some point in their lives.

It might happen after a long day on your feet, during pregnancy, after surgery or following an injury. Sometimes it's temporary, while other times it may persist or return regularly.

Swelling is not a condition itself. It's a sign that fluid has accumulated within the body's tissues.

Understanding why this happens is the first step in understanding how to support your body's natural fluid balance.

What Is Swelling?

Swelling, also known as oedema, occurs when excess fluid collects within the body's tissues.

This can happen anywhere in the body, including the:

  • Legs

  • Ankles

  • Feet

  • Hands

  • Face

  • Abdomen

  • Arms

Some swelling is a normal response to injury or surgery, while other types may be related to changes in circulation, the lymphatic system or underlying medical conditions.

Why Does Swelling Occur?

Fluid is constantly moving between your blood vessels and your body's tissues.

Normally, this fluid is collected by the lymphatic system and returned to the bloodstream.

Swelling occurs when more fluid enters the tissues than the body can comfortably move away.

This may happen because of:

  • Surgery

  • Injury

  • Pregnancy

  • Reduced movement

  • Prolonged sitting or standing

  • Inflammation

  • Certain medications

  • Some medical conditions affecting the heart, kidneys, veins or lymphatic system

Because swelling can have many different causes, understanding the reason behind it is important.

Common Types of Swelling

Everyday Fluid Retention

Many people notice mild swelling after long periods of sitting, standing or travelling.

This often improves with movement, elevation and time.

Pregnancy

Hormonal changes and the growing uterus can slow the return of fluid from the legs, making swelling in the feet and ankles common during pregnancy.

After Surgery

Swelling is a normal part of the healing process after surgery.

As tissues repair, fluid naturally moves into the area to support healing.

Depending on the procedure, your healthcare team may recommend Manual Lymphatic Drainage as part of your recovery plan once it is appropriate to do so.

After Injury

Sprains, strains and other injuries commonly produce swelling as part of the body's normal inflammatory response.

Lymphoedema

Lymphoedema is a chronic condition caused by a reduced capacity of the lymphatic system to transport lymph.

It requires specialised assessment and management.

The internationally recognised Vodder Method® Manual Lymphatic Drainage is one component that may be used as part of a comprehensive lymphoedema management plan by appropriately trained practitioners.

When Should Swelling Be Assessed?

While mild swelling is often temporary, persistent or unexplained swelling should always be assessed by a healthcare professional.

Seek prompt medical advice if swelling:

  • Appears suddenly

  • Is severe

  • Affects only one limb without an obvious reason

  • Is associated with significant pain

  • Occurs with redness or heat

  • Is accompanied by shortness of breath or chest pain

These symptoms require medical assessment and should not be managed with Manual Lymphatic Drainage alone.

How Can Manual Lymphatic Drainage Help?

Manual Lymphatic Drainage (MLD) is a specialised, gentle treatment designed to support the natural movement of lymphatic fluid through the body's lymphatic vessels.

At Embody Lymphatic Co, treatments are performed using the internationally recognised Vodder Method®, which is recognised worldwide for its precise and evidence-informed approach.

MLD may be appropriate for people experiencing certain types of swelling, including post-surgical swelling and pregnancy-related swelling, when clinically appropriate.

A thorough health assessment is always completed to ensure treatment is suitable for your individual circumstances.

Supporting Healthy Fluid Movement Every Day

While not all swelling can be prevented, healthy lifestyle habits help support the body's natural circulation and lymphatic function.

These include:

  • Regular movement

  • Walking

  • Deep breathing

  • Changing positions regularly

  • Staying hydrated

  • Following your healthcare provider's advice after surgery or injury

These simple habits encourage the natural movement of fluid throughout the body.

Frequently Asked Questions

Is all swelling caused by the lymphatic system?

No. Swelling can result from many different causes, including injury, surgery, pregnancy, venous conditions, medications and underlying medical conditions. An assessment is important to determine the likely cause.

When is swelling considered normal?

Mild swelling after injury, surgery, prolonged standing or pregnancy can be a normal response. However, swelling that is persistent, worsening or unexplained should always be assessed by a healthcare professional.

Can Manual Lymphatic Drainage reduce swelling?

MLD is designed to support the natural movement of lymphatic fluid and may be appropriate for certain types of swelling. Whether it's suitable depends on the cause of the swelling and your overall health.

Why is one leg more swollen than the other?

Swelling affecting only one limb may have several possible causes and should be assessed by a healthcare professional, particularly if it develops suddenly or is associated with pain, redness or warmth.

When should I avoid treatment?

Some causes of swelling require urgent medical assessment before any hands-on treatment is considered. Your practitioner will discuss your medical history and determine whether treatment is appropriate or whether referral is needed.

Understanding Your Body's Signals

Swelling is your body's way of telling you that fluid balance has changed.

Sometimes it's a normal part of healing. Other times it may indicate that your body needs further assessment or support.

By understanding why swelling occurs, you can make informed decisions about your health and seek the most appropriate care for your individual needs.

At Embody Lymphatic Co, every assessment begins with understanding the cause of your swelling so that treatment is safe, personalised and appropriate.
