preventing circulation

Overview

Poor circulation happens when blood flow to parts of your body slows down or is blocked. This often affects your arms, hands, legs, and feet. Your body needs a steady supply of blood to deliver oxygen and nutrients to your cells and remove waste products.

Yes, poor circulation is common, especially as people get older. Many people experience mild symptoms like cold hands and feet at some point.

It can happen to anyone, but it is more likely in people who smoke, have diabetes, high blood pressure, or high cholesterol. It also becomes more common with age.

Symptoms

Common symptoms

• Cold hands or feet
• Tingling or pins and needles
• Numbness
• Swelling in the legs or feet
• Tired or heavy legs
• Skin color changes (pale, blue, or red)

Symptoms in children

• Cool or mottled skin
• Tiredness during feeding or play
• Slow growth or development

Symptoms in older adults

• Cramping in the legs when walking
• Foot or leg pain that gets better with rest
• Dry or shiny skin on the legs
• Slow-healing sores on the feet
• Weak pulses in the feet

Causes

Main causes

• Atherosclerosis: a condition where fatty deposits (plaque) build up inside your arteries, narrowing them and reducing blood flow
• Blood clots: a clot can block an artery or vein and stop blood flow
• Blood vessel inflammation (vasculitis): swelling of the blood vessel walls can narrow or close them
• Diabetes: high blood sugar can damage blood vessels over time

Risk factors

• Smoking or using tobacco
• High blood pressure
• High cholesterol
• Diabetes
• Obesity or being overweight
• Lack of physical activity
• Family history of heart or blood vessel disease
• Age over 60

When to see a doctor

See a doctor urgently if:

• You have chest pain or shortness of breath
• You have sudden weakness, numbness, or difficulty speaking
• You have severe pain, swelling, or discoloration in one leg or arm

Book a routine appointment if:

• You have cramping or pain in your legs when walking
• Your hands or feet are often cold or numb
• You have a sore on your foot or leg that is not healing

Diagnosis

Your doctor will ask about your symptoms, your medical history, and any habits that affect circulation, such as smoking. They may also do a physical exam to check your pulse, skin color, and temperature.

Tests that may be done

• Ankle-brachial index (ABI): a simple test that compares blood pressure in your ankle and arm to check for narrowed arteries in your legs
• Doppler ultrasound: a scan that uses sound waves to check blood flow through your veins and arteries
• Blood tests: to check for diabetes, high cholesterol, or blood clotting problems
• Angiography: an imaging test where dye is injected into your blood vessels to see where blockages are

What to expect at your appointment

These tests are usually done as an outpatient, which means you do not need to stay overnight. Most are painless. Your doctor will explain the results and talk with you about the next steps.

Treatment

Treatment for poor circulation focuses on improving blood flow, reducing symptoms, and lowering your risk of more serious problems like heart attack or stroke. It often involves lifestyle changes and, sometimes, medical care.

Self-care at home

• Stop smoking or using tobacco
• Move more: walk, stretch, or do gentle exercise most days
• Keep your feet clean and dry, and check them for cuts or sores
• Avoid sitting or standing for long periods
• Keep your legs warm and elevated when resting
• Wear comfortable shoes that do not pinch

Medical treatments

Your doctor may recommend medicines to help manage high blood pressure, cholesterol, diabetes, or blood clotting. These are different from person to person. Your doctor will decide which treatment is right for you and explain what each medicine does. Always take prescribed medicines exactly as directed.

When is surgery considered?

If your circulation is severely blocked and symptoms don't improve with lifestyle changes and medicines, your doctor may talk about procedures to open or bypass the blocked artery. These include angioplasty (a small balloon inflated inside the artery) or a bypass graft (creating a new route for blood to flow). These decisions are always made with your specialist team.

Living with this condition

Living with poor circulation means paying attention to your body. Check your feet daily for cuts, blisters, or color changes. Avoid extreme cold, and keep your skin moisturized to prevent cracks.

Lifestyle tips

• Quit smoking
• Eat a balanced diet with plenty of fruits, vegetables, whole grains, and healthy fats
• Stay active with activities you enjoy, like walking, cycling, or swimming
• Maintain a healthy weight
• Manage stress with relaxation, breathing, or talking to someone you trust

Diet and exercise

Choose foods low in salt and unhealthy fats. Include plenty of fiber. Try to get at least 30 minutes of moderate exercise on most days. If walking hurts, rest for a little while, then continue. A doctor or physiotherapist can help you plan a safe routine.

Mental health and emotional wellbeing

Living with a chronic condition can feel tiring or worrying. It is normal to feel frustrated or anxious at times. Talking to someone, joining a support group, or seeing a counselor can help you cope.

Prevention

You can prevent or slow down poor circulation by keeping your blood vessels healthy. The most important steps are not smoking, staying active, eating well, and managing health conditions like diabetes, blood pressure, and cholesterol.

Vaccines

Some infections can increase your risk of blood vessel problems. Staying up to date with recommended vaccines, like the flu and COVID-19 vaccines, helps protect your overall health.

Screening programmes

If you have a higher risk due to diabetes, high blood pressure, or family history, your doctor may recommend regular check-ups to monitor your circulation and catch problems early.

Complications

If left untreated

• Unhealed sores or wounds that may become infected
• Tissue death (gangrene) which can require amputation
• Blood clots that travel to the lungs (pulmonary embolism) or brain (stroke)
• Heart attack or stroke if the underlying artery disease progresses

Long-term outlook

The outlook for poor circulation depends on the cause and how early it is treated. With proper care and lifestyle changes, most people can manage their symptoms and reduce their risk of serious problems. Getting help early and following your treatment plan makes a big difference.
