Hello Doctor: My father has diabetes and has recently experienced swelling in his foot, which extends beyond the sole to the ankle, but it is only affecting one foot.
He has seen a metabolic specialist who found no issues.
Which department should he consult?

Dear Ms.
Emily:
1.
There are many causes of lower extremity edema.
Generally speaking, if the edema is bilateral, one should consider heart failure, nephrotic syndrome, hypoalbuminemia, cirrhosis, medication side effects, pregnancy, hypothyroidism, and other potential causes.
If the edema is unilateral, one should consider venous obstruction, venous insufficiency, lymphedema, lipedema, and other causes.
Of course, whether bilateral or unilateral edema, there may also be other rare causes.
2.
Without considering individual patient factors, I would suggest evaluating for deep vein thrombosis, cellulitis, erysipelas, or other causes of lymphedema; similarly, there may be other less common diseases.
If necessary, bacterial cultures, blood tests, angiography, or ultrasound examinations may be required.
These situations involve specialties such as cardiology, infectious diseases, metabolic disorders, and radiology.
3.
I recommend that you discuss and analyze the situation with your father's attending physician to determine which specialty he should be referred to for diagnosis and treatment based on his condition; this would be a more appropriate and reasonable process.

More Info

When dealing with persistent swelling in one leg, especially in the context of a patient with diabetes, it is essential to approach the situation with a comprehensive understanding of potential underlying causes. Given that your father has diabetes and is experiencing unilateral leg swelling (swelling in only one leg), there are several possible conditions that could be contributing to this issue.

Firstly, it is advisable to consult a vascular specialist, also known as a vascular surgeon or a phlebologist. These specialists focus on disorders of the blood vessels, including veins and arteries. Unilateral leg swelling can often be attributed to venous insufficiency, deep vein thrombosis (DVT), or other vascular issues. DVT, in particular, is a serious condition where a blood clot forms in a deep vein, usually in the legs, and can lead to complications if not treated promptly.

Additionally, it may be beneficial to see a diabetologist or an endocrinologist who specializes in diabetes management. Since diabetes can lead to complications such as peripheral neuropathy and circulatory issues, these specialists can help assess whether the swelling is related to your father's diabetes or if it is a separate issue that requires attention.

Another important consideration is the possibility of lymphedema, which is a condition characterized by swelling due to lymphatic system blockages. If the swelling is due to lymphedema, a consultation with a lymphedema therapist or a specialist in physical medicine and rehabilitation may be warranted.

In some cases, rheumatologists may also be consulted if there is suspicion of inflammatory conditions such as arthritis or other autoimmune disorders that could cause swelling in one leg.

It is crucial to ensure that your father undergoes a thorough evaluation, which may include imaging studies such as an ultrasound to check for DVT or other vascular issues, blood tests to assess for infection or other systemic conditions, and a detailed medical history to identify any other symptoms that may be present.

In summary, the best course of action would be to start with a vascular specialist to rule out any serious vascular conditions, followed by consultations with endocrinologists or other specialists as needed based on the findings. Early intervention is key, especially considering your father's diabetes, to prevent potential complications and ensure appropriate management of his health.
