Have you ever noticed swelling in your ankles at the end of the day, puffy fingers in the morning, or tightness in your shoes that wasn’t there before? Many people experience these symptoms and wonder whether it’s just temporary — or something more. In some cases, this swelling may be oedema, also known as fluid retention.
At Homed-IQ, we support people in understanding and monitoring their health from home. Recognising the signs of fluid retention early can help you take practical steps to manage it — and spot when it might be linked to an underlying health issue.

What is oedema?
Oedema is the medical term for swelling caused by excess fluid trapped in the body’s tissues. It most commonly affects:
-
Legs
-
Ankles
-
Feet
-
Hands
-
Arms
-
Face
Fluid moves constantly between your blood vessels and body tissues. Normally, your body keeps this balance under control. But when too much fluid leaks into surrounding tissue — or isn’t drained properly — swelling can occur.
This is why oedema is often referred to as fluid retention (Cleveland Clinic, 2026).
Recognising the symptoms of fluid retention
The symptoms of oedema can range from mild to more noticeable.
Common signs include:
-
Swelling in the legs, ankles or feet
-
Puffy hands or fingers
-
A feeling of heaviness or tightness
-
Stretched or shiny skin
-
Indentations in the skin after pressing (known as pitting oedema)
-
Sudden weight gain from fluid build-up
A simple self-check
Gently press your finger into a swollen area for a few seconds.
-
If the skin springs back immediately → swelling may be mild or temporary
-
If an indentation remains → this could indicate fluid retention
Mild swelling that improves with rest is often harmless. However, persistent, worsening, or painful swelling should be checked by a healthcare professional (NHS, 2025; NHS, 2025).
What causes oedema?
Oedema can happen for many different reasons.
Lifestyle-related causes
-
Sitting or standing for long periods
-
Lack of movement
-
High salt intake
-
Hot weather
Medications
Some medicines may cause fluid retention as a side effect, including:
-
Blood pressure medication
-
Hormone treatments
-
Anti-inflammatory drugs
Hormonal changes
Fluid retention is common during:
-
Pregnancy
-
Menstrual cycles
Underlying health conditions
Sometimes oedema may signal an underlying issue, such as:
-
Heart problems
-
Kidney disease
-
Liver conditions
-
Poor circulation
If swelling appears suddenly, affects only one limb, or comes with shortness of breath or chest discomfort, seek medical advice promptly (MayoClinic, 2023).
Practical tips to reduce fluid retention at home
Mild oedema can often be managed with simple lifestyle adjustments.
Try the following:
-
Keep moving: Gentle walking or stretching helps circulation and prevents fluid from pooling.
-
Elevate affected areas: Raise your legs or arms above heart level when resting.
-
Reduce salt intake: Too much sodium encourages fluid retention.
-
Stay hydrated: Drinking enough water helps your body maintain fluid balance.
-
Wear comfortable clothing: Avoid tight garments that restrict circulation.
-
Support circulation: Compression socks may help in some cases.
If swelling persists or you’re unsure of the cause, monitoring your health with a home test can provide additional insight before speaking with a healthcare professional (MedlinePlus, 2025; Cleveland Clinic, 2026).
Taking control of your health
Oedema is common — and often manageable — but it can sometimes signal something more significant. By paying attention to symptoms and making small daily adjustments, you can reduce fluid retention and better understand your body.
If you’re unsure about ongoing swelling, home health testing can offer reassurance and clarity. Explore Homed-IQ’s range of health tests to take a proactive step towards understanding your wellbeing.
Frequently asked questions about oedema
Can oedema go away on its own?
Yes — mild oedema caused by temporary factors such as heat, inactivity or hormonal changes often resolves on its own. Movement, hydration and rest may help. However, persistent swelling should be assessed (Cleveland Clinic, 2026).
Is fluid retention always a sign of a serious health problem?
No — many cases are harmless and linked to lifestyle or temporary changes. But ongoing, sudden, or severe swelling may indicate an underlying condition and should be checked by a healthcare professional.
Frequently asked questions
How reliable are the tests?
Our tests are analysed in an ISO 15189 accredited laboratory with the same equipment and protocols used by hospitals and GPs. The accuracy is comparable to a venous blood draw.
How quickly will I receive my results?
After receipt of your sample at the lab, you will receive your results within 1-2 working days in your personal, secure portal.
Are the tests really anonymous?
Yes, 100%. The packaging is plain, containing no indication of the contents. Your test is registered with an anonymous code. Only you have access to the results.
