Your circulatory system is responsible for delivering oxygen and nutrients throughout your body — and when it’s not functioning properly, your health can be at serious risk. Circulatory problems often develop slowly and silently, making early detection critical for preventing complications such as heart attack, stroke, or chronic venous disease.

At GLMI, we help patients across Buffalo, Williamsville, Cheektowaga, Orchard Park, and Cambria identify the warning signs of vascular and venous problems through advanced imaging. Understanding what to look for — and when to act — can make all the difference in maintaining your long-term health.

Why Circulation Matters

The circulatory system consists of your heart, arteries, veins, and capillaries — all working together to move blood throughout the body. When any part of this system becomes blocked, narrowed, or weakened, circulation slows or becomes inefficient. Over time, this can cause tissue damage, pain, or even organ dysfunction.

Poor circulation isn’t just a symptom of aging. It can be caused by underlying conditions such as diabetes, high cholesterol, hypertension, or obesity. Lifestyle factors like smoking, lack of exercise, and prolonged sitting or standing can also contribute to circulatory issues.

Common Early Warning Signs of Circulatory Problems

Circulatory issues can affect different areas of the body in different ways. Recognizing the early warning signs allows for faster diagnosis and treatment before more serious complications develop.

1. Cold Hands and Feet

Persistent coldness in your extremities can indicate reduced blood flow, especially if accompanied by numbness or tingling. While cold hands or feet may seem harmless, they can be an early sign of peripheral artery disease (PAD) or other circulation-related conditions.

2. Leg Pain or Cramping (Especially When Walking)

If you experience pain, cramping, or fatigue in your legs after walking short distances that improves with rest, it may be a sign of PAD — a condition caused by narrowed arteries that limit blood flow to the limbs. Early diagnosis through ultrasound or CT angiography can prevent disease progression and reduce your risk of serious cardiovascular events.

3. Swelling in the Legs or Ankles

Swelling (edema) in your lower legs and ankles may indicate that blood is pooling due to weak or damaged veins. This is often associated with venous insufficiency or heart-related issues. Chronic swelling should always be evaluated by a medical professional.

4. Skin Discoloration or Texture Changes

Darkened, shiny, or reddish skin — particularly around the ankles or calves — can signal circulation problems. The skin may also feel cool, thin, or develop ulcers that heal slowly. These visible changes are your body’s way of signaling inadequate oxygen delivery to tissues.

5. Numbness, Tingling, or Weakness

Frequent “pins and needles” sensations or weakness in your hands and feet can be signs that your nerves aren’t getting enough oxygen-rich blood. Over time, chronic poor circulation can cause nerve damage (neuropathy), especially in people with diabetes.

6. Varicose or Spider Veins

While often considered cosmetic, varicose and spider veins can be early indicators of underlying venous disease. When valves inside your veins weaken, blood can pool and create visible, bulging veins under the skin. Vein evaluations at GLMI can help determine whether these veins are harmless or require medical attention.

7. Slow-Healing Wounds

Cuts or sores on your legs and feet that take an unusually long time to heal are often signs of poor circulation. Without sufficient blood flow, your body can’t deliver the nutrients and immune cells needed for proper wound healing — increasing infection risk.

8. Fatigue or Shortness of Breath

When circulation is compromised, your body must work harder to deliver oxygen. This can lead to overall fatigue, weakness, or shortness of breath during light activity. These symptoms should never be ignored and may require diagnostic testing to rule out vascular or cardiac issues.

How Imaging Helps Diagnose Circulatory Problems

Imaging is one of the most effective ways to identify vascular and venous issues early. At GLMI, we use advanced imaging technologies to detect blockages, measure blood flow, and evaluate the condition of arteries and veins throughout the body.

1. Vascular Ultrasound

Ultrasound uses sound waves to visualize veins and arteries in real time. It’s the most common and non-invasive test for detecting blood clots, plaque buildup, or valve dysfunction. Vascular ultrasound can also assess how effectively blood is moving through the body.

2. Low-Dose CT Scans

CT imaging can reveal structural changes in blood vessels, detect aneurysms, and evaluate the severity of arterial blockages. GLMI’s low-dose CT technology reduces radiation exposure while maintaining superior image clarity, making it ideal for vascular assessments.

3. PET/CT Scans

When doctors need to evaluate both the structure and function of blood vessels or heart tissue, PET/CT imaging provides a comprehensive view. It helps identify inflammation, tissue damage, or metabolic abnormalities that may not appear on other imaging studies.

Why Early Detection Is So Important

Catching circulation issues early allows doctors to intervene before permanent damage occurs. In many cases, lifestyle changes, medication, or minimally invasive treatments can restore healthy blood flow and prevent severe complications.

Without early detection, circulatory problems can progress to serious outcomes such as:

• Chronic venous insufficiency
• Deep vein thrombosis (DVT)
• Peripheral artery disease (PAD)
• Non-healing ulcers or infections
• Heart attack or stroke

By combining advanced imaging with clinical evaluation, GLMI helps your physician develop a proactive care plan tailored to your specific needs.

Protecting Your Circulation Through Prevention

Even if you haven’t experienced symptoms, maintaining good circulation should be part of your preventive health routine. Here are simple ways to keep your vascular system healthy:

• Stay physically active — walking, swimming, and stretching all boost blood flow.
• Eat a heart-healthy diet rich in fruits, vegetables, and lean proteins.
• Avoid smoking, which damages blood vessel walls and reduces oxygen delivery.
• Elevate your legs when sitting for long periods to encourage venous return.
• Schedule regular vascular screenings if you have risk factors such as diabetes, obesity, or family history of vascular disease.
