Why Are My Elderly Parent's Legs Swollen? Guide to Leg Swelling and Oedema

If you've noticed that your elderly parent's legs or feet seem more swollen than usual lately, it's understandable to be worried. The swelling is often caused by oedema, which happens when extra fluid builds up in the body's tissues and causes water retention in the legs. This can develop for various reasons, from sitting for too long or eating more salty foods than usual. That said, swollen legs in elderly people could be a sign of a more serious underlying health condition, so you shouldn’t completely ignore it, especially if it doesn’t improve over time.

In this guide, we'll walk you through the most common reasons why your elderly parent may have swollen legs. You’ll also learn when to seek medical advice and how our nurse-led care at Right at Home Central London can help your loved one stay comfortable and mobile in their residence.

Your parent may experience leg swelling in old age because of:

• Lifestyle factors – Eating too much salty food and not staying hydrated can cause their body to retain more fluid. Likewise, spending most of the day sitting down or being inactive can reduce circulation.
• Medications – Certain blood pressure medications, hormone therapies, antidepressants, and steroids can cause water to build up in your parent’s lower extremities.
• Underlying medical conditions – If the swelling persists or happens suddenly, it may indicate an underlying health problem such as heart failure or kidney disease, and in some cases lymphoedema. Swelling may also result from circulation problems, including deep vein thrombosis, where a blood clot forms in a deep vein.

Mild swelling often improves with rest and simple self-care. However, you should seek medical advice straight away if your parent experiences any of the following:

• Sudden or severe swelling in one leg, especially if it's painful and red or warm to the touch.
• Swelling in both legs together with breathlessness and chest pain, or unusual fatigue.
• Rapid weight gain or swelling that becomes noticeably worse over a few days.
• Skin that becomes tight and shiny or discoloured, or even develops sores or ulcers.
• Swelling that doesn't improve even after your parent has rested or raised their legs.
• Yellowing of the skin or dark-coloured urine, which may suggest a liver or kidney problem.

Many older adults in Central London live in flats where there isn't much space to move around. If your parent spends most of the day sitting, it's easier for fluid to collect in their legs and make swelling worse. With home care, your parent receives one-on-one attention that makes it easier to monitor their lifestyle habits and swelling in the legs.

A carer can encourage your parent to keep moving in small, gentle ways throughout the day. It could be something as simple as wiggling their toes or stretching their feet, or even accompanying them to take a short walk around the home or outside if they’re able. These little movements help improve circulation and can reduce fluid buildup that causes oedema in elderly legs over time.

They can also help your parent put their feet up safely and comfortably. For example, they might place pillows under their legs while they're sitting or lying down. When appropriate, raising the legs above heart level can help fluid move away from the lower limbs. This can help your parent manage swelling and make their legs feel more comfortable, even when they’re resting.

At Right At Home Central London, your parent also receives tailored support from our Carers who can help them with their daily routines to manage oedema. This can include:

• Wearing compression socks correctly
• Providing a soothing foot soak
• Ensuring your parent drinks enough water to stay hydrated
• Checking the skin daily for redness or sores
