When exhaustion and lower-leg swelling aren't explained by diabetes, the heart and veins are the next places to look. Both are evaluable with ultrasound at our Falmouth imaging center — this week.
When you're tired all the time and your feet are swollen — and you've already ruled out diabetes — the next question is whether your heart is working as hard as it should. Heart failure, valve disease, and pulmonary hypertension can all produce this exact combination of symptoms. So can venous insufficiency in the leg veins. The only way to tell them apart is imaging.
GET ANSWERS IN DAYS, NOT MONTHS
If you're tired all the time with swollen feet — and you know it's not diabetes — your heart may not be pumping efficiently. An echo at our Falmouth imaging center takes 45 minutes and checks exactly that. No referral. No waiting room. Cardiologist-reviewed results in 24—48 hours.
If you develop sudden severe shortness of breath, chest pain, coughing up frothy fluid, or one leg that is suddenly much more swollen, red, and painful — call 911 or go to the nearest emergency room immediately.
Fatigue and lower-leg swelling together, without a diabetic explanation, tend to point in a cardiac or venous direction. Here are the four most important causes to evaluate:
Heart failure doesn't mean the heart has stopped — it means the heart isn't keeping up with the body's demands. When the left ventricle's ejection fraction falls, less blood is pumped out per beat, and the body receives less oxygen-rich blood. The result is persistent fatigue that doesn't respond to rest. Simultaneously, fluid backs up into the body's tissues, pooling in the legs and feet by end of day. An echocardiogram measures ejection fraction directly and can help identify whether reduced pump function is contributing to symptoms.
Heart valves control the direction of blood flow through the heart. When a valve becomes leaky (regurgitation) or too narrow to open fully (stenosis), the heart must work harder to maintain circulation. Significant aortic stenosis or mitral regurgitation can produce fatigue and exercise intolerance as early symptoms — often years before more dramatic symptoms appear. An echocardiogram evaluates all four valves and can help identify the severity of any dysfunction.
Pulmonary hypertension — elevated pressure in the lung's blood vessels — forces the right side of the heart to work harder than it was designed to. Over time, the right ventricle can enlarge and weaken, causing fluid to accumulate in the body (right heart failure). Symptoms include fatigue, swollen legs, and shortness of breath with exertion. An echocardiogram can estimate pulmonary artery pressures and evaluate right ventricular size and function, and can help identify this condition before it becomes severe.
If the heart checks out normally, the next place to look is the leg veins. Venous insufficiency — where one-way valves in the veins fail and blood pools — causes swelling, heaviness, and aching in the lower legs. The fatigue associated with venous insufficiency tends to be localized to the legs rather than systemic, and it's typically worse at end of day. A venous duplex ultrasound maps valve function and can help pinpoint exactly where the reflux is occurring.
Start with the echocardiogram — it covers the three cardiac causes in one study. Add a venous duplex if the heart is normal and venous cause is suspected.
Echocardiogram · $397 in Falmouth — Primary
A comprehensive cardiac ultrasound measuring ejection fraction, evaluating all four valves, assessing diastolic function, estimating pulmonary artery pressures, and evaluating right ventricular size. The single most informative study for cardiovascular causes of fatigue and swelling. 45-minute home visit, no radiation, cardiologist-reviewed report in 24—48 hours.

Duplex ultrasound mapping of the major leg veins from groin to ankle. Evaluates valve competency, identifies reflux (backward blood flow), and rules out deep vein thrombosis. Recommended when the echo is normal or when leg symptoms are disproportionately heavy/achy compared to the overall fatigue picture.

Heart failure and significant valve disease respond far better to treatment when caught early. Waiting months while symptoms progress means allowing the heart to remodel under stress — a process that's harder to reverse. Every month of unexplained fatigue is a month of unmanaged cardiovascular load.
Our registered cardiac and vascular sonographer scans at our Falmouth imaging center, or comes to your home with portable ultrasound equipment. A single study is $397 in Falmouth or $597 at your home. No fasting required. No waiting rooms. You stay comfortable in your own space throughout.
For the echocardiogram, ultrasound gel is applied to the chest and a transducer images your heart from several positions. The study evaluates all four chambers, all four valves, ejection fraction, diastolic function, and estimated pulmonary pressures. Takes approximately 45 minutes. Completely painless, no radiation.
If a venous duplex is also performed in the same visit, the probe scans the leg veins from groin to ankle with you lying flat, evaluating each vein segment for valve function and blood flow direction. Another 30 minutes, also painless.
Our sonographer walks you through key findings before leaving. The formal cardiologist-reviewed written report arrives within 24—48 hours — ready to share with your primary care physician or any specialist you're seeing.
Yes. Heart failure, valve disease, and pulmonary hypertension are among the most common non-diabetic causes of this symptom combination. When the heart doesn't pump efficiently, fluid backs up into the legs and overall energy falls due to reduced cardiac output. An echocardiogram can help evaluate all three cardiac causes in a single study.
Pulmonary hypertension is elevated blood pressure in the vessels of the lungs, which forces the right heart to work harder. Over time the right ventricle can enlarge and fail, causing fluid to back up into the body — leading to swollen legs, fatigue, and shortness of breath. An echocardiogram can estimate pulmonary artery pressures and evaluate right heart function.
No referral is required. You book directly through our website and book our Falmouth imaging center. A board-certified cardiologist reviews every study with a written report in 24—48 hours.
Yes. Our sonographer holds credentials in both cardiac and vascular ultrasound. An echocardiogram and venous duplex can be performed in the same home visit. Package pricing is available when combining multiple scans.
Seek emergency care immediately for sudden severe shortness of breath, chest pain, coughing up pink or frothy fluid, rapid heartbeat with loss of consciousness, or one leg suddenly much more swollen, red, and painful than the other. Gradual, chronic fatigue with swelling is appropriate to evaluate on a scheduled basis.
