Abnormal swelling of the feet, often accompanied by unexplained inflammation, is a serious medical emergency requiring immediate care. Experts state that unexplained foot swelling may be a key sign of health problems such as diabetes, kidney diseases, heart diseases, and others. If you experience foot swelling, pay attention to these conditions. Foot swelling occurs when heart function is impaired, making it difficult for the heart to pump blood efficiently, leading to cell death. Edema, another term for foot swelling, results from excess fluid accumulation due to poor circulation. Kidney damage can also cause abnormal foot swelling because the kidneys lose their ability to remove excess fluids, leading to accumulation and swelling. Liver dysfunction may cause fluid retention in the legs and feet; if swelling is accompanied by jaundice or abdominal swelling, urgent medical care is needed.

Blood clots in leg veins can block blood flow, causing swelling and pain, requiring immediate medical consultation. Diabetic patients may develop foot infections causing swelling, redness, and pain, which if untreated can lead to serious health complications.
